I have the following configuration
Asus prime Z270-p
Celeron 3930
4gb DDR4
6x RX480 (MSI gaming x 4gb version)
M.2 harddrive

When i try to use more than 3 card the system does not boot up(actualy does not even show up the bios press delete option if i recall correctly)

I have enabdled the above 4g decoding(newwest BIOS) and set all PCIE to gen 1. Is there anything else that needs to be set in order for 6 cards to work? I'm clueless what I'm doing wrong.

Turn off 4g decoding. Add 1 card at a time. Once the 5th card is installed, and the drivers installed, and youre in windows and its showing a code 12, THEN turn on 4g decoding.

Here is a walk-through I found on Youtube that got me up and running with my Asus H270 Plus.  Probably same settings in the Bios

https://bitcointalk.org/index.php?topic=1899977.0

I have the same mb, I gotten 5 cards to work, with 4g decoding turned on, and all settings possible set at gen 1, when I plug in card 6 it shows bios splash 2 times then black screen.

Thank you all, i will try the adviced steps.

Pluging in the cards one by one in consecutive reboots worked, thank you for the tip (8 hours uptime so far)  ;D


Try gen 2, i switched to Gen 2 too.

with z270a with 8 gpu i use gen 3,
with gen 1 not work on linux, but it work only on window don't tell me why.

Can you help me please. I have Prime z270-a. I already update the bios. actually all available bios update on asus website. why i dont get the settings 4g enable? can someone help me please. i cant run more than 4cards :( PLEASE HELP. Thank you!

My problem is when I add 4th graphic card my loading page comes like this:
http://azaraeen.com/no-usb.png
I have tried "above 4g" but system goes to a boot loop with no picture.

Searched the forum it was already answered. It was something with UEFI.

Greetings everyone!

I am wondering is anyone running Asus Prime Z270-P on Ubuntu 16.04 - Desktop.

I had 4 GPU-s running smooth and when i added 5th if i had 4G decoding, i had blank black screen when i booted, if i turned it off i could log with 5 gpus but system didnt recognize fifth, had only GPU 0 1 2 3. If i removed 5th card i had problems again lol.


SO basicaly i can do this - have 5 gpus with 4G on and have 1 as not recognized or have 4 with 4G off. Its something like that, maybe it was vice versa, but basicaly system either didnt boot even with 5 gpus or it didnt shown 5th if it managed to boot.


But anyway! Can anyone help me please how to set up BIOS and options in there to have 5 6 or even more GPUS working on my ASUS prime 270p


PLEASE HELP!


I BEG YOU

Bump :((

I'm not sure what the equivalent in Linux is, but for 'Above 4G Encoding' set to enabled to work with Windows, it has to be installed in UEFI mode enabled. I'm guessing Linux has something similar. You probably have to install Linux with UEFI enabled.

It could be that or something. I will try it out. Thank you a lot!

This mainboard f*cking sucks... Driving me crazy... All I know is, when you enable 4g decoding, you will have to have an OS that has UEFI and not MBR, otherwise it wont boot.

This thing is driving me nuts.... seriously.

I get it to work with simple mining os but it crashes all the time. Cards have stock clocks.

I have this mobo with Windows 10 Pro and 6 AMD GPUs was working very well. I've ordered M.2 to PCI-E adapters so will it test with 7 and 8 GPUs, but I don't have anymore GPUs now :D
All GPUs OCed and udervolted with modded bios. I had only problem with detecting cards before installing new drivers, run DDU twice with rebooring solve it. I'm installing drivers with iGPU as monitor and then connect HDMI to GPU in x16 slot on mobo.

This is why I advocate that people have hard drive led status lights and not just a power button for your rig. That little led has helped me TS rigs so many times I've lost track. I run Linux (Ubuntu 16.04) and had issues initially with getting this board to work.

I updated the bios to 0610 via the built in flasher in the bios
Changed all PCIe speeds to Gen2 and turned off what I didn't need like HD Audi, LED light and USB charging
Rebooted, but after the bios screen my screen would go blank.

Luckily I had my hard drive led status light as even though the screen was blank it was blinking, which let me know it was reading/writing to the drive and not frozen or locked up. So I gave it time to do its thing and low and behold it booted. Seems the GRUB menu doesn't load with above 4G decoding enabled, hence the black screen but the OS does eventually boot. Had I not had that HDD led I would of just taken the blank screen as a sign things aren't working and shut it down premature.

Hope the above helps someone

GUYS  SOLUTION!!!


I've been sitting here and try to get this dumb piece of sh*t to work for almost 3 days now.

So here it is:

All you have to do is download Bios v0808 (http://"http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/PRIME_Z270-P/PRIME-Z270-P-ASUS-0808.zip?_ga=2.33293694.1301838499.1498481932-1488656230.1478723779") that has been released 23.06.17. Put it on a USB stick which is formated with fat 32 (internet update didn't work with me for some reason)

 - Remove all Cards/ Risers, plug in your USB Stick with the Bios on it. Plug in your HDMI Cable to the motherboard.

 - Boot

 - While booting express your rage by hiting that mf*cking f2 key several times to enter the Bios.


 - After entering the Bios, press F7 and navigate to Tools


 - Open EZflash and choose Upgrade from Storage. Update your Bios to Version 0808.

 - Reboot while pressing F2 several times again to Enter BIOS

 - Press F7

 - Go Advanced ----> System Agent (SA) Configuration ----> Enable "Above 4 G Decoding"

(DMI/OPI CONFIGURATION --->DMI MAX LINK SPEED will stay at AUTO! Dont change these..)

(PEG PORT CONFIGURATION ---> PCIEX16_1 LINK SPEED will stay at AUTO ! Dont change these..)

 - Go back to Advanced, then PCH CONFIGUTATION ---> PCI Express Configuration----> change PCIe Speed to "GEN1"


That should do it!


Some other usefull stuff:

 - Advanced ---> APM Configuration ---> change Restore AC Power Loss to "Power ON" (Rig goes on as soon as PSU delivers Power, no need to press on button or short pins)
 - Boot---> Next Boot after AC Power Loss, change to "Fast Boot" (boots faster)
 - Boot---> Boot configuration ---> Post Delay Time, change to 0 sec (for no Post delay, in Case miner restarts.)

When done in BIOS, Press F10, Save and reboot.


prey.


Hope this helps... ASUS PEOPLE, YOU DIDNT MAKE THIS EASY FOR US

TNX

Mine worked yesterday by plugging in 5 cards, disabling 4g, booting windows (won't properly load more than 1 card), reset, enable 4g, profit. But it's very nice to know that there's another solution out there. Thanks for sharing.

All my PCI-E options set to Gen2, audio disabled.

I also have issues with my rx 580 with asus z270-a mobo, described here https://bitcointalk.org/index.php?topic=1961377 , will try this solution later

Yesterday I was able to run on my friend's Z270P 6x Asus Dual 1060 6GB with almost no problems.
My Z270P was running 6x AMD 470/480 also very good, didn't test m.2.

Hi Guys,
              I am new here and I was also having the same issue , till 2 GPUs Z270P was working fine but once I add my 3rd GPU windows was crashing. So I upgrade bios 1st to the latest version of now which is PRIME-Z270-P-ASUS-0610.CAP , For me also Internet download was not working so simply I install from usb stick.

1st : Upgrade BIOS to 610 version
2nd : Go Advanced ----> System Agent (SA) Configuration ----> Enable "Above 4 G Decoding"
3rd : DMI/OPI CONFIGURATION ---> DMI MAX LINK SPEED change to GEN1
4th : PEG PORT CONFIGURATION ---> PCIEX16_1 LINK SPEED change to GEN1

Thats all I did not change PCH CONFIGUTATION configuration like other bro did and for me now mining is stable and running without any windows crash etc. from last 20 hours.


Share is care. So keep sharing and keep Caring

I think it really depends on what Bios version you got. On earlier Bios I could run it halfway stable put all options on Gen3.

It can run only with 4G above enabled with 6 GPUs on 0610...

Hi
   Which Bios and setting you used for your rig.

4G above, 0608

Try during 8h to have my 6th GPU reconnized but not works..
Only 5 GPU is detected on W10..

I Start thinking to change the Motherboard but when i see its working for some people, im so frustated..

Hello Friends,

has anybody managed to make 8 gpus work on this Asus Prime  Z270-P.  I have connected 7th and 8th gpu to the M.2 to PCI-e convertor but did not manage to see them added in device manager (windows 10).

Any Bios settings I need to change ?

I am using latest Bios 0808 released on 23-07-17.

Thank you.

I'm getting crazy with this mobo (Asus prime z270-p)

I was really happy when I saw this thread that a lot of people managed to get their rig working but unfortunately I am not able to get it up and running with more than 4 GPUs. My last hope is that one of you can give me another tip. I tried already the following:

- BIOS upgrade to version 0808
- 4g is enabled and everything is working up to 4 GPUs
- DMI/OPI, PEG Port and PCI-E: tried Auto, Gen1 and Gen2 in all combinations
- Onboard Sound, Serial, SATA and USB is disabled

Any Idea what I'm doing wrong?

Any help is appreciated.

have u tried to disable 4G like suggested here ?

got it to work but will need to reset daily as the motherboard does not have sufficient power

With 4G disabled I am only able to get up and running with 2 cards......... As soon as I insert the 3th one I see only a cursor blinking. Not even possible to enter the BIOS.
With 4G enabled I can get up and running with 4 cards..........

Any other ideas?

I got 8 gpus (8x580s Strix) running on Z270P.. you need to be careful with how you install everything and making sure updates are turned of, a lot of the times, your drivers are updated, and theyre not compatible with 8 gpus. it took us 1 day but we finally managed to do it, and replicate it on 2 other rigs.

wts guide for 0.01613 btc, please pm

Have u tried 4g disabled (with just one card installed) and adding Card 2 - Reboot - Card 3 - Reboot - Card 4 - Reboot - Card 5  Reboot ?

Or .... disable 4G, boot with 1 card, install it and then shutdown. Connect all the remaining cards, boot, enable 4G, voila.

I tried that as well: 4 disabled with one card (ok) - reboot adding card 2 (ok) - reboot adding card 3 --> only a blinking cursor not even possible to enter the BIOS

exactly the same issue: booting with 1 card and 4G disable is fine - after adding 4 more I can't enter the BIOS.
I tried enabling 4G booting with one card - shutdown adding 4 more cards --> I can enter the BIOS but Windows is not booting. I never see a Windows logo or something and the screen is always switching between it looks like there will be a picture and back to there is no picture.........

Update:

I did install Windows 10 from scratch with the following BIOS settings
- 4G disabled
- all onboard devices disabled
- everything to Gen1

After some Windows Updates I did install the first card --> everything fine
added the second card --> everything fine
added the third one got an error before the bios
removed the third one - changed 4G to enable --> everything fine
added the 4th card --> everything fine
added the 5th card --> Windows is starting but I have a "code 43" error in the device manager for the last card

I searched a lot for this error and it seems to be a common issue but only with older Windows versions (not Windows 10).

Changing from Gen1 to auto didn't change something. I am still able to boot Windows even with "auto" but still have the code 43 error.

Any idea how to fix that?

@cryptobob88, thanks a lot for your help. We could figure out that my problem is pretty sure one GPU which is Fu**** up......
I learned a lot and his help was really professional :)

I will receive another card tomorrow and should know after if it's working with 5 cards.

You're welcome! Good luck :)

I'm having the same problem. Can you make to make it work yet? I'm using GTX 1050Ti, what I've tried so far can make windows 10 sees only 6 cards.

Tnx for this hint ;) You made my day. I feel like an idiot now because i was allways adding 1 by 1  :)

Im using nvidia card and the latest bios https://www.asus.com/us/Motherboards/PRIME-Z270-P/HelpDesk_Download/

got my 8 gpu detected

you should use 4g enabled

good luck

Try not plugging in the power to the M.2 to PCIe connectors ... it seems to work for me ... also one of the M.2 power connectors cable burned so I wouldn't recommend them anyways.

Thank you deadsix!!! All I have to do is remove power connector from M.2 PCIe adapter!!

My rig is now running full 8 cards. Thanks!!

tried this but nothing working so far , any ideas ?

I can't find the BIOS 0808 version on the Asus website? Also, your link doesn't work?

are you using m.2 to pcie adapters?

Someone know where to download BIOS 0808 for Asus prime Z270-p?
I can't find this BIOS on the Asus Support site... is it because the Asus support site is buggy?

https://mega.nz/#!o3pXFSCC!R3sW5PMSVCr-8apaj8QpX96PCXpuShnjvolFvOEa0Ys (https://mega.nz/#!o3pXFSCC!R3sW5PMSVCr-8apaj8QpX96PCXpuShnjvolFvOEa0Ys)

Use it at your own risk. Maybe asus removed it for a reason.

Thanks!

I'm going crazy...
Have 2 z270-p
Both have the same kaby lake pentium g4560. 1 have 1x4GB and the second 1x8GB ram.
Both have the same win7 ultimate x64 on sata ssd.
1st board mines with 7 gpu without any problem, in any slot combinations using M2_1 or M2_2 slot. 8th gpu shows on device manager but with the !
2nd board can see and use correctly 5 gpus. Each additional is not seen in the device manager at all.
Both have 0808 bios and same setings... Offcourse tried different settings on mobo2 aswell.
1st have 5x1060+2x1070 and the additional 1060 or 1070 showing ! in device manager
2nd have 2x1080ti, 1x1080,3x1070 and 1x1060 and cannot see more than 5 in the device manager.

Where is the problem? Mixing gpus? 1080ti consuming more resources?
Maybe I'll test putting the ti's on the first mobo...

I've installed 0808 bios on two Z270-P mobos, working great so far.

My second rig started working with all 7 gpus... But I don't know why after so many hours of headaches  ;D

Good news to all Asus Prime Z270-P owners!
BIOS 0810 is out!

https://www.asus.com/us/Motherboards/PRIME-Z270-P/HelpDesk_Download/

Hi,

I've a Z270-P with Windows 10
GPU : Asus GTX 1070 Strix
Bios : 0810 (same issue with 0808)

6 GPUs are fine and super stable

As soon as I plug a 7th GPU on a M.2 adapter. Everything is fine (I can see 7 GPU) but it crashes and reboots after roughly 30 to 60 minutes of mining.

Any ideas? I've tryed 3 M.2 adapters and 2 risers: same result.

I have in the Bios pzd3mir's settings

Hi Guys,
             So M2 Slot are not working good for GPU's and crashing or on M2 we do not have to use Power plug (White cable) . Anyone have a stable 8 GPU running on Z270-P with 2x M2 slot ? if yes please share input/steps. thanks

I've tried unplugging a 7th card, but not the one in M.2 slot. And it's stable!

So this means the M.2 slot is perfectly fine and it's probably a bios or windows issue with 7+ GPUs

I guess I'll have to try Ubuntu ...

add some gig on virtual memory ...im using 0610 and they run smoothly.....

I've tried adding more virtual memory (like 20 GB) and same issue.
Btw, I've checked and while mining, system is using less than 3 GB of RAM, and I've 8 GB installed.

Dears I am also having the same issue now, 6 GPUs are fine but 7 GPU on M.2 slot Windows get crash sometimes after 3 , 4 Random time and when I check Windows even it show display driver crash and recover.

Asus release new Intel Graphic Driver , Chipset driver for Windows 10 Stability issue.
AMD installing latest AMD driver 17.7.1

Will share the result with you guys if it get stable.




If anyone of you able to run stable Z270-P with 7 or 8 GPUs on Windows 10 x64 , please share your bios setting and drivers details to help us

Hi Guys,
             Good news for me now system is stable up and running without any issue for 7 GPUs, I have not tried 8 GPU till now but I believe that will work also.


For all those who are struggling with this issue. please follow below steps

First remove all the GPUs and perform below installation and then start connecting GPUs. (Better one by one)

Uninstall all the Intel drivers , Chipset driver.

Windows 10 x64 (restart system after every windows driver installation)

1 : Install Chipset Driver latest from Asus Website 19/7/2017
2 : Install new Graphic driver latest from Asus Website 19/7/2017
3 : Install latest Lan Driver latest from Asus Website 19/7/2017
4 : Install Latest Sata driver

AMD :
Install Latest driver 17.7.1 with all the features
Run Overclock Patch if card are overclock
Restart

on Bios :
Keep all the PCIe option to Auto except PCH Config :
1. DMI/OPI CONFIGURATION --->DMI MAX LINK SPEED will stay at AUTO
2. PEG PORT CONFIGURATION ---> PCIEX16_1 LINK SPEED will stay at AUTO
3. Advanced -->  PCH CONFIGUTATION ---> PCI Express Configuration----> change PCIe Speed to "GEN1"
4. Enable 4G decoding once add more GPU's

The bios 0808 and all 3 pci-e related settings to gen3. Pimary gpu adapter set to pcie, audio disabled, serial port disabled.

thanx for the guide, in 10 days I will try to add 2 more cards to my rig, will see how it goes

Hello, any1 noticed if AC power on power loss stopped working with the latest BIOS?

Well, not exactly, with older BIOS, you could power on only tapping the power button on the power supply. But I updated to latest BIOS (to have 4G decoding enabled) and now it doesn't turn on the same way. I must unplug the power cord first, plug again and then it works, but it's a bit of an inconvenience.

Its meant for accidental shutdowns or power losses. If you just turn the mains off and back on, system will boot. If you shutdown your pc properly, well then its not accidental, and just turning power back on will not work immidiately, thats not what the feature is built for.
In such a case as you stated, you need to power cycle, which means turn off the PSU and wait a minute for the capacitors on the PSU/motherboard to discharge.

Ok, I understand, it is just before the BIOS update, you could turn on (from user shutdown) any moment you wanted. I was using it this way because I read that this is the way to go when you don't have a case or power button (first rig).


Thanks 4 reply.

You could always just start it by connecting the PWR_SW pins on the motherboard together. I'm just using a screwdriver for this, works like a charm!
https://www.youtube.com/watch?v=RDxffHFbFJc

On the z270 Prime its the two pins to the top right, if I remember correctly. The pins should be marked with text below.

Win 7 ?  i have tried 6 but not yet 7... anyway 8 gpu is not a problem with z270p + win10 ...


anyone tried 12 gpu....?

goodluck

ETH mining? It must be amd then... nvidia is another story. AMD works also with pci-e spllitters so no problems running more cards in a single rig.

Nope its Nvidia .... there is no option for amd here in my country......

I currently have 7 gtx 1070 running and am just waiting on the 8th card to arrive.  Thanks to those who posted on this thread as I read all of it before getting my rig to run last weekend!

It's currently using two evga cards, two msi cards, two zotac cards and one asus card (with another asus card coming).  It just sort of worked out in pairs as I purchase four cards used and four cards new from Amazon.

915 Watts.  Less than I expected.

Just need to make sure everything is stable before doing some cable managing.

Hi everybody!

I see a few have 8 gpu's running via M.2 adapters. Can SATA and M.2 ports be used at the same time or do you have to boot from an USB-drive?

On my both rigs i get 8th gpu detected in device manager and everything seems ok for few seconds but then 1 of the gpus allways gets an exclamation mark.
So I hope it's win 7 related and i'm going to try win10.

In win 10 8 gpu setup works without even installing separately the nvidia drivers. I would be happier to achieve it with win 7 but at least it works ;)

I've got 7x 1070's running in my rig also. I'm using the blue version 006c 6pin risers. I set mine to "gen1" pcie. does gen1, gen2, or gen3 work better?

First thing I did was the bios update to 810 then enable '4G decoding'.  I started the bios setting at gen2 for all without success and then gen1 for all without any success.  I then tried leaving everything on auto and just setting the pcie configuration on gen1 and all seven cards were recognized.  After all the video cards were seen, I didn't try adjusting the setting at all.  It took a weekend to get my rig up and running I didn't want to test to see if there were gains to be made from setting anything on gen1 or gen2.  

I am also using the blue 006C version.  Odd thing is the first eight I ordered from Amazon came with the little tabs that lock the riser on the card but the second time I ordered it, it came without the tabs but seems to fit much tighter on the card.  They are both working fine though.  I ordered the second set thinking it was the risers that was causing the original problem but that wasn't it.

On a side note my two MSI Armor Geforce GTX 1070 OC Edition 8GB seems to run the hottest at 60-64 degrees.  Others are in the 50-55 range.  

How many GPUs are you running? I am only able to get 7 to register in windows and linux. Doesn't seem to recognize #8.

one advice for making 6+ gpu rigs: first of all make sure that one single cards shows picture on monitor stabbed in EVERY single PCIe and M.2 or PCIe splitter or whatever else you use, until than you have to play with those GEN1,2,3 settings. Mine board (h270 plus) is working with everything set to GEN2. Also not to mention that 4g decoding ON is must option. For 8+ GPU you have to use win10 (dont know about win 8.1), 7 gpu works fine on win7. Also have in mind that m.2 adapters are shitty quality and half of them doesnt work, so picture test is must option

I received my 8th card yesterday and popped it in, turned on the computer and everything is all good.  Bios version 0810, 006c risers, generic M.2 pcie converters and ssd running Windows 10 Pro.  I did install the latest drivers from Asus for LAN, VGA, and I think chipset.  I left audio alone as it's disabled.  I am not sure if the driver updates are a must or not but I figured it couldn't hurt.

http://tohktohk.com/pics/miner1.jpg
http://tohktohk.com/pics/miner2.jpg

Many times there is a big china factor causing problems... The risers and m.2 adapters should allways be the first suspects ;)
As said... win 10 must work with 8 gpu if all the hw is ok.

i got the asus Z270-P and 13GPU's

i have problems getting more than 7 to work.
I got this pcie extensions. Looks like a riser but u can connect up to 4 risers to it.
When i connect 8 cards. Sometimes it only get 5, sometimes 6 and sometimes 7. But never all the 8.
Also the system keeps crushing, and flashing black screen.

Is it at all possible to get more than 8gpu's working on that board? I have problems getting the riser extensions to work ~~

i am using windows 10, but rdy to change the os if this will solve my problem ~~

This config worked for me. I couldn't make it work with more than 4 GPUs
Special notes:  I had the latest BIOS installed. I think it's 0810
I had connected my monitor to my onboard GPU and did not work.
I disconnected the monitor and started windows 10 with no monitor. I usually connect and manage my miner with teamviewer or google remote desktop.
it worker with 5 GPUS.

Thanks for your great help.

anyone try the 2270-A?

it has 7 slots and two m2s as well

answered my own question it worked, this one actually has two m2 slots so theoretically it could do 9 but im told windows 10 only recognizes 8

i have z270a, 9 cards on linux and 8 cards on Windows, works well.
A guy in YouTube can run even 12 cards on this mobo, i haven't tired.

you could do 8 amd and 4 nvidia on windows right? 

Theese boards are a little bit tricky but once you get them to work they work like a charm ....
I lost like 3 days to get CARBON board from msi to work with 7 cards ....

yeah same here fuck msi carbon, these ones at least work if you do all the required steps
I returned all my msi carbon boards and pros

I don't have a amd card.

If you still have problems disable the internal GPU and connect your monitor for setup to the card in your first x16 slot.
Add one card after another.
Happy mining!

P.S. if you connect a monitor to the mainboard, the internal GPU gets activated automatically.

I have to say, the 0810 BIOS is best. I just recently added a seventh card to my z270-p that had a 0610 BIOS and it was crashing every 5-10minutes, updated to 0810 and made the necessary gen1 change. viola, works great.


can we have 8 gpus and the onboard graphics at the same time?

yes

@ssdaytona: which GEN1 config worked for you?
DMI MAX LINK SPEED? PEG PORT CONFIGURATION? PCH CONFIGUTATION?

I have all those set to gen3. All my problems came from bad m.2 adapters or risers. The new risers seems worse to me than the old ones with molex power connectors. More bad pieces...

It took me a while to get all 6 gpu's recognized but I managed after many attempts!  Now I'm tempted to try a 7th and 8th GPU using m.2 PCIE adapters like some of you guys, but how are you powering a 7th and 8th GPU?  I'm using a EVGA 1200W power supply and it only has 6 VGA connectors/cables and I assume it's not a good idea to use a Y-splitter cable for the extra two GPU's.  My 6-rig GPU is using about 735W as I'm limiting the power to 60% on MSI Afterburner.

Are you guys using a SATA-PCIE cable of some sort?  Is that safe?

PEG Port config. I changed it to gen1

p.s. I now have 8 gpus and onboard graphics running at same time. I am very surprised that no one has gotten 9gpu's to run on widows. I might try with the z270-a that I have coming.

Im using:

ASUS Prime Z270-P
6 x MSI RX 580 8GB Hynix memory
64-bit Windows 7


Board has 4x 1x PCIE and 2x 16x PCIE.

If I plug same card in all 1X PCIE it's working. If I plug in two 16x PCIE, computer doesn't recognise the card.

Is it fault 16X PCIE ports ( faulty motherboard) or is some settings in BIOS ?

well I am splitting my vga cables. I figured that they can power 150w cards for the 8pin connector, so I used a splitter and with a undervolted 1070 or 1060, it seems to be working fine. cables aren't even warm to touch.

Plug in one card to one of the 16x slots to see if the computer sees it.  Now test the other 16x slot with the same card.  If both slots work with one video card then most likely it's not a faulty slot on the mobo.

There is something wrong with both 16X PCIE, beacuse in BIOS under Advanced-PEG Port Configuration option PCIEX16_1 is set to NOT PRESENT !!! I can't change that value, on working motherboard in other rig, this setting is set to x1.

Update BIOS.

ok this is a strange one , i got a third AR version of this chipset its the prime Z270-AR

the other two are working fine with 8 cards , 7 on pcie and one on m2 adapter , this board

worked fine wth 4g decoding and 5 cards, two days later tried to add 3 more cards, now it crashes right away after bios screen, uninstalled drivers wit uud, i see all 8 cards , crashes again when trying to update driver.

tried to rol back to my original 5 card build removing the extra 3 cards same crash when installing drivers

same crap happens when i reinstall win 10 ... flakey board?

try to install an older nvidia driver.

how this can help?  ???

Hi, i have a serious issue with my new z270-p board. No slots works with risers, i have tried them with a dozen differrent. All the right settings in bios (4g envoding, gen 1 etc), latest bios and fresh windows 10 install. Gpu-fan is running but cards doesnt show up, tried with 5 different cards (and they do work connected directly in pci-e slot). Any ideas?

If you plug the vid card directly in and it works, then it's not the mobo, power supply, OS or driver.  You are only left with how everything is connected with the riser (everything seated correctly).  Have you tried  just one video card with the riser?  Try resetting the mobo to factory and plug in just one video card with the riser.  It won't matter if 4g encoding is on or not with one card.  The point is to get one working to rule out what you can before complicating it with multiple cards.

It would help to isolate driver issues.  The OP mentioned this is his third Z270-AR board.  Is it running the same vid cards and OS? 

What kind of riser ? molex, sata, 12v only

How do you connect power in ?

Hi, they are usb3 with molex on riser card and an additional 6-pin pci-e at the card.

It was an amd build, It was a bad card or something maybe the riser

It sounds like you don't have above 4G decoding enabled.  Verify it's on advanced - system agent (sa) configuration - above 4G decoding in bios.  Updating the drivers is probably a good idea as well for LAN, Chipset, SATA, and VGA.

https://www.asus.com/us/Motherboards/PRIME-Z270-P/HelpDesk_Download/

Others are just drivers for the motherboard not a must, but a good idea to do as they are driver updates put out by Asus. 

Are you using the same cards as the other two rigs?

one thing I found on this board is if you have less than 5 cards it will not boot with 4G decoding turned on

I've got the ASUS Prime Z270-P as well and have been running into issues with 810..

I've got the same PCIE screen representing only 1 slot..which deviates from previous things I've read as well.

I have same bios, no problem at all...

ok cool, up and running with 1 GPU on Z270-p...now to install the other 14

Hi,

I'm having problems getting m.2_1 to detect pci-e, there is no problem with the hardware as it all works on m.2_2

Would you please share your bios settings,
1. DMI/OPI (gen 1, gen 2, gen 3 or auto) ?
2. PEG Port (gen 1, gen 2, gen 3 or auto) ?
3. 4G decoding (enable / disable) ?
4. PCH / PCIe config (gen 1, gen 2, gen 3 or auto) ?
5. Onboard devices M.2_1 config (auto or PCIe) ?

Are the m.2 adapters powered or unpowered?

If anyone else has a working Z270-P with both m.2 detected as PCIe please share the above settings in your bios.

There is a lot of conflicting advice on every single point everyone has a different opinion as to what works. I've already tried all options/ combinations to get the m.2_1 to be detected as pcie but no...

PLEASE HELP! WILL REWARD!! $

I'm desperate  :-\

https://www.youtube.com/watch?v=4cd1qoTAHmA&t=20s

My m2 adapter is unpowered and I am using those settings

https://www.youtube.com/watch?v=DR-FkpU2KfI&t=309s

Did not have any problems

Hi thanks for the reply.

Iv'e watched both these videos before,

https://www.youtube.com/watch?v=4cd1qoTAHmA&t=20s


https://www.youtube.com/watch?v=DR-FkpU2KfI&t=309s

 it's for 270-A not 270-P but similar enought just the P hasn't go as many options.

To sum up he recommends:
1. DMI/OPI gen 2
2. PEG Port gen 2
3. 4G decoding enable
4. PCH / PCIe config  gen 2
5. Onboard devices M.2_1 config - auto

which do not work for me. anyway I tried all different combinations already I think and not working.

Can someone send photos of their actual bios page by page or tell me what I'm missing

thanks

PS. I'm just trying now to get 2 GPUs only to work from the m.2_1 slot (not working) and m.2_2 slot (already working)
that's all, not multi gpu complex problem
Please help will reward $

OMG!!!! I got it to work! :o ;D

the problems was with the gold connectors of the shitty chinese m.2 adapter

wiggling it around and pushing it in didn't help at all!!!

what did help was following Asus recommendations on installation of m.2 cards but not from the Z270-p manual, those are not there! I looked by chance at the Z170 manual.

I followed the instructions carefully, FIRST screwing in the m.2 card and THEN bending it into place. VERY SCARY!! I felt like I was going to snap the card in 2 or snap the motherboard or snap my fingers, bending those shits is hard!!!

finally it's done!

both cards recognised :)

here is where to download the manual https://www.gigabyte.com/Motherboard/GA-Z170-Gaming-K3-rev-10#support-manual it's page 15, (I couldn't find how to attach photo here)

ENJOY!!! ;D

I am under the impression there may be more than one bios setting that works so I can only tell you what I have.  I just copied it from my previous post since I am feeling lazy lol. 


"First thing I did was the bios update to 810 then enable '4G decoding'.  I started the bios setting at gen2 for all without success and then gen1 for all without any success.  I then tried leaving everything on auto and just setting the pcie configuration on gen1 and all seven cards were recognized.  After all the video cards were seen, I didn't try adjusting the setting at all.  It took a weekend to get my rig up and running I didn't want to test to see if there were gains to be made from setting anything on gen1 or gen2. 

I am also using the blue 006C version.  Odd thing is the first eight I ordered from Amazon came with the little tabs that lock the riser on the card but the second time I ordered it, it came without the tabs but seems to fit much tighter on the card.  They are both working fine though.  I ordered the second set thinking it was the risers that was causing the original problem but that wasn't it.

On a side note my two MSI Armor Geforce GTX 1070 OC Edition 8GB seems to run the hottest at 60-64 degrees.  Others are in the 50-55 range." 


I currently have two rigs.  Both using same hardware with the only difference being 8 cards on one rig and the 6 cards on the other.  All 14 cards are GTX 1070.  Same bios settings and not powering the m.2 adapter on the rig with 8 cards.  I didn't see a need for it as power is being provided to the riser and the gpu. 

Hi,

Now that everything is working and fresh in my mind I wanted to go through step by step installation from beginning to end:

1. Install just motherboard. it means CPU, memory, SSD, NO wires NO adapters NO GPUS

2. Plug motherboard into power not forgetting power to 8 pin CPU

3. Power up make sure first of all the thing works and you can access the bios. (forget about all the tutorial videos where they build the thing from beginning to end and it just works, that shit don't work!)

4. Once you can access the bios, update it to the latest version. There are instructions online and in the motherboard manual. It's really not that scary.

5. set up your bios ready for the next steps:
 a) DMI/OPI  is gen 2
 b) PEG Port is gen 2
 c) 4G decoding - enable (I find there is no harm in enabling 4G early even before you have multiple GPUS but if you have issues do it later after 3rd GPU)
4. PCH / PCIe config is gen 2
5. Onboard devices M.2_1 config is auto (M.2_2 setup options are not found as this is set to PCI-e by default it should just work)
There are other settings for making things more convenient but these are not critical to setup

6. After setup install windows

7. setup all your risers but NO GPUS yet!
POWER TIPS:
- make sure if you are using a daisy chain SATA or Molex power that you don't put more than 2 or 3 risers per connection to PSU. It might not take the load and give you errors.
- I also burnt 2 motherboards in early setups connecting adapter to adapter - don't do it! take the original psu power cable and connect each end (if daisy chain you will have multiple) to ONE chinese splitter. don't connect one splitter to another splitter. I use the molex one male to two female adapter works fine.
- Make sure non of the cable touch the metal body of your GPU those get very hot and melt the cables.
-don't share cables between PSUs corsair and Antec and EVGA they are all wired up differently and don't share you could burn up your setup
-there are MANY things that can go wrong with power. each Riser would need about 75W on it's own so 850W supply might just be enough for 8 risers and M/b. If you use heavy power GPUS like 8 x R9 390 you will need at least another 2 PSUs as these will draw at least 200W each. AT LEAST!

8. Install the two m.2 adapters m.2_1 and m.2_2 make sure you follow asus recommendations I followed the instructions carefully, FIRST screwing in the m.2 card and THEN bending it into place. VERY SCARY!! I felt like I was going to snap the card in 2 or snap the motherboard or snap my fingers, bending those shits is hard!!!

9. start up the PC after each step just to make sure nothing was messed up in between steps

10. So each PCIE riser is powered now and you can connect just ONE PCIE riser to ONE m.2 connector. NO NEED TO CONNECT m.2 adapter to power as PCIE your riser is already powered.

11. update windows

12. download all latest drivers from asus website, chipset, LAN and Video  ALSO download latest driver from AMD website but DON'T yet install the AMD video driver.

13. disconnect Internet. uplug it. shut down

14. Install 1 GPU inside the first PCIE riser (the one you connected to m.2_1) Power up should boot fine.

15. In windows open device manager make sure your 1 GPU is detected as some generic video adapter.

16. shut down. Install second GPU in PCIE riser connected to m.2_2. boot up, at this point both m.2 converted to PCIe should be detected by windows as generic display adapters. good.

17. Keep adding 1 GPU at a time and booting up and making sure detected by windows between each addition. (after 3 GPUS make sure your bios is setup for 4G decoding). sometimes it may take a few minutes for device manager in windows to detect new GPU, wait patiently. by the end of this you should see 8 GPUs detected by windows.

18. shut down. Unplug all your PCIE risers from motherboard (no need to physically pull out GPUs from risers)

19. plug in just one PCIE-riser to motherboard and boot up into windows

20. install latest AMD graphics driver that you downloaded before.

21. Driver should install successfully detecting the 1 GPU you have connected.

22. shut down, connect second riser, reboot make sure it's detected not as generic

23. repeat process connect one PCIE riser with 1 GPU at each reboot, check and repeat

Hopefully by the end of it all you will have 8 gpus detected.

If I left anything out please comment and I will ammend

GOOD LUCK! :D

PS sometimes GPUs are not detected on first reboot. reboot 2 or 3 times with same settings to ensure you really have a problem

Very long and instructive list of steps. I think this will help new users of same brand and model. Regarding GPU detection, I have experienced same issue with an Asrock mobo. I had to reboot several times to see all gpus in action.

Fellas,

I  have an Asus prime Z270-a and it's supposed to run up to 8gpu, though I can't even get the 4th to work.

I have 3 GTX 1070 and 1 R9 390 to run on there. the r9 390 isn't showing up in device manager.  I've configured all my PCI-e links according to everyone video I've seen on the board, but the 4th card just isn't showing up.  This isn't my first build, though it's only my 3rd and my first time on Asus.

Yes, the bios is updated
Yes, I've tried 3 different Risers, though the first two are known to work.
Yes, I'm only plugging the risers card into PCI-E 1x slots.
Yes, the card works when plugged into the board with no other cards.

Thank you.

I cannot install AMD drivers as no device is recognized.

Did you enable Above 4K Decoding?

BIOS version 0812 is out. It says "Improve memory stability & compatibility" and I think updating a stable rig should not be necessary. But ASUS has for some reason removed BIOS 0810 from the download site while older versions are still available.
You are probably aware of it but updating the BIOS over the internet from the tool menu in BIOS does not always work. Sometimes it does not work at all, and if it works you may get an old version. You will probably have to download it and put it on an USB stick.

I have built 5 rigs with Prime Z270-P (6GPU) and one 8 GPU rig with Prime Z270-A. Ive spent endless hours getting the rigs up and running and read all kinds of good and bad advice on various forums and Youtube channels. For some reason the third rig was a pain and I really don't know what solved the problem in the end. The last one was a breeze and I plan to build more 8 GPU rigs with Z270-P.
Bear in mind that a lot of the post you read are old and the problems described may not apply to you now as BIOS firmware and Windows/GPU drivers has been updated. I set the 3 different PCI speeds to GEN2 and GEN1 on my first rigs to get them running, but I have now set them back to Auto on all my rigs. I think Above 4G Decoding is the only thing you have to enable in BIOS.

Here is my BIOS setup:

Above 4G Decoding Enabled
SATA6G_2(Gray) Disabled
SATA6G_3(Gray) Disabled
SATA6G_4(Gray) Disabled
Restore AC Power Loss Power On
HD Audio Controller Disabled
LED Lighting Disabled
Charging USB device in Power State S5 (Disabled)
Serial port Disabled
USB3_1 Disabled
USB3_2 Disabled
USB3_3 Disabled
USB3_4 Disabled
USB11 Disabled
USB12 Disabled
USB13 Disabled
USB14 Disabled
Boot logo Disabled

Explanation:
Above 4G is needed to allow some of the GPU's to be memory mapped above the 4GB address space. There is not enough room below 4GB and the CPU/OS will not be able to use all GPS's. Usually you had to enable it when you connected the 4th GPU, and if you removed GPU's you would have to disable it again to boot the OS. But as ozhaveruk mentioned in a post above, you can now enable it right away before you install the GPUs.
SATA 2-4 is disabled to free up resources.
Restore AC Power Loss, so the rig starts after power loss.
Audio is disabled because no audio will be connected and drivers will not have to be installed.
LED lights are disabled because I don't need the extra attention.
USB Charging, the rig will never be in Power State S5 and I will certainly not charge anything
Serial port is disabled to free up resources
All internal USB ports are disabled to free up resources. The ports listed are the ones that are not on the back panel. They are the ones you are supposed to connect to the front panel of you PC cabinet with a cable connected to the mainboard.
Boot logo is disabled as I would rather see the technical info during boot.

But as I mentioned above 4G is probably the only setting you would have to change, and having the PC power on after power loss is also nice. I really have no idea if it helps in any way to disable SATA,USB and serial ports, but It can't hurt.

I do not think it is necessary to download and install any drivers from ASUS. I did this on one rig only and it did not seem to make a difference.
It is a good idea to connect the monitor to the mainboard VGA or DVI until all GPU's are installed.
You seem to need luck or good karma to get a multi GPU rig going. Voodoo maybe. Often you scratch your head for hours, swapping GPU's and risers and cables, and then for no apparent reason whatsoever, the last GPU is detected by Windows. I everything seems to be right but one GPU is not detected, it can help connecting the monitor to the problem GPU during power up.

A few comments to ozhaveruk's posts:

You have an error in the numbering of your list. 4 and 5 appear 2 times. My comments below refer to the numbers on your list:

point 5. a, b and what should have been d about PCI speed: not necessary. Try setting it to auto on your rig and see what happens.
point 5 about M.2: This is not a change is it? auto is default?
point 7 Avoid splitters and daisy chains on power if possible. If you plan your build and buy the right PSUs and riser's you don't need the chinese splitters. 3 risers on one PSU cable is much, to avoid that you may be have to use 2 or 3 smaller PSUs instead of a big one.
point 8 I really don't understand what you are on about here. You also posted a link to a Gigabyte manual earlier that you followed step by step. If you secured the adapter board with the screw first, and then bent it into the connector, you are very lucky that you did not ruin you motherboard. There is a screw and a spacer for the M.2 in a plastic bag. (Unlike Gigabyte where the screw and spacer is already fastened to the motherboard). The spacer should be fastened to the motherboard at the right position according to the legth of the m.2 device. Insert the M.2 adapter into the connector at an angle. It should slide in very easy and it should be very easy to push it down so it is horizontal to the motherboard and resting on the spacer. Secure it with the screw.

Other then that my procedure is not identical to yours, but it is probably not important. One uses the the same method that has been proven successful. Do you know why you insert one and one card without the driver installed? And do you know why you install driver with only one card present?
One thing that annoys me is that Windows usually freeze when I update the AMD driver. Maybe it would not if I disconnected all but one card?

Cheers!

Yes i did but that Should only affect memory mapping over 4gb and not Windows detecting the gpu....according to the list below

I'm going to try to disable sata ports as i don't use them.
Any other idea?

_kaurus can you check if your HDD or SSD is partitioned with MBR or GPT? MBR does not support Above 4G Decoding, but the symptom should be system lockup.

https://www.howtogeek.com/245610/how-to-check-if-a-disk-uses-gpt-or-mbr-and-how-to-convert-between-the-two/

Other then that I would remove one of the 1070's to see if the R9 390 got recognized. Or check if the system will accept 4 or more 1070's if you have more.

This drive was setup on another system and transferred to this mobo. It was running 10 1070 + 2 390s.  Do you think i should still try the mbr version?

No. It should be GPT. If you used the drive with 12 GPUs it is GPT.

This other system is also a Z270-A? If not I would reinstall windows from the mobo you are going to use.

for my rigs on Z270-P with 6 cards that option PCIE-X GEN speed became most crucial!!
if it was set to auto - no luck on loading, no keyboard, no HDD
if set on GEN1 - nu loading
if set on GEN2 - stable and running good
if set on GEN3 - not stable loading

I don't know what to say, but I guess for some rigs this option is important as well

I'm using a MBR partitioned ssd with win7 and it works with 7 nvidia gpus. On the asus prime z270-p offcourse.

I just did a test on one of my rigs and it will boot Windows 10 and mine regardles of what PCIe speed is set to, Gen1, 2 and even 3. That is with BIOS version 0810. 3x580 Nitro+,1x570 Nitro+, 1x580 Gigabyte Gaming 8 and 1x1070 Zotac Mini
Unless your BIOS older than 0810, it may depend on the graphics cards and/or the risers used?

I was under the impression that Microsoft used MBR by default on all windows installs. So why would i have an MBR issue to recognize additional cards.  

My AB350 board did 6 cards (not of the same brand), my asrock does 8+2 and now this Asus prime Z270-a only does 3 cards of any type.  All systems are running off a normal laymen's install of windows.

Hello have someone successfully try 8 GPU on this mobo? Or do you recommend Z270-A? Tnx for the answers :)

i have 8 running in windows without issue

turn on 4g
and dont use the power cords for the 2 m.2 riser cards, it works fine without them.

I have 6 rigs with 8 GPUs and this motherboard. It has been troublesome to get them running because the m2 adapters that I got is of terrible quality. Some work and some don’t. I just found out that they are full off solder “balls” and bridges.

https://imgur.com/a/9Sp8f
Is this a good M.2 riser?

@manicdan What do you mean with power cards?

This is the one I'm talking about:
https://i.ebayimg.com/images/g/-f4AAOSwTapV4-qz/s-l1600.jpg

As you can see it has a small 4 pin power connector. You don't have to use it as the riser itself is powered.

The one your looking at is probably a good choice.

I guess I can get this "adapter/riser thing" on e-bay right?

AliExpress

So it turns out these boards only like certain risers. Version 6 i believe. This is why my board only saw 3of6 gpu.

Swapping risers solved my mobo's identifying issues

My ASUS boards like ALL risers, the Biostar boards are choosy though.

It's much better to get this adapter.  you can run upto 4 devices from this one.  I am using one with 4 cards plugged in.  no additional power required by the adapter either.  Just ensure you get the VER 002. 

https://www.aliexpress.com/store/product/PCI-E-to-PCI-E-Adapter-1-Turn-4-PCI-Express-Slot-1x-to-16x-USB/605305_32833259844.html?spm=2114.12010611.0.0.649f3bbb809U1s

 I had an incident of that m.2 pcie adapter burnt out.  Luckily didn't damage any components on the board.  The pins below can get bent and short out.

This works 100%??

I am using 2 cards.  All 4 ports work for me on 2 separate Z270 motherboards
Imo it's definitely worth trying out yourself for 14 bucks odd.

Does a Celeron 3930 work on this motherboard out of the box? Not too keen on swapping a cpu in just to update bios.

Yes!

So you can potentially run 9 GPU's with this adapter plus the other 5 slots?

Is anyone running these right now can say how they're working?


Thanks heavyarms

Mine's running 9 on Z270P.  Yes It works fine.

Thanks. :)
Are you on windows 10?
Also what kind of gpu are you running? amd or nvidia
Did you need to change any settings after installing this 4 in 1 card?

Windows 10 and Linux.  Works on both.  No settings changed.  Works fine with 4G encoding enabled.
I haven't been running 9 cards from single vendor yet (since I am on blockchain drivers and 8 is the driver limit).  I have tried running 3xNvidia + 6xAMD on Win10 and it worked.

Thanks!
Do you think it'll be more stable if I run all amd cards (different model, vendors,) versus just running amd on the 5 pci-e slots and the nvidia on the 4 in one expansion slot?

All the expansion card does is communication over USB protocol.  The GPUs are doing the work.  Since you'll be using risers, it doesn't matter what pci-e slots you use.  The expansion card is just a multiplexer switch providing 1x to 4x

Thanks.
In that case I'll add the 4 in one to the very last slot that way it'll be easier to keep track of the cards connected physically in case one of them doenst work properly.

humm ,im new here ,
i bought Z270 P + 6x 1060 3BG

i updated to lastest bios 818 ,
and motherboard dont want take more than 5 gpu ,

anyone have lastest bios ( 818 ) legit bios from asus ( i have made internet update )
i followed configuration from video ( internet ) from guy minning with 8 1060 gpu..

but dont take the 6th card ( i disconected 1 card to plug 6th )
i got always 5 cards ( the 6th card & plug/wire work )

i have 8 cards but more than 5 no working ...

You need to insert the card in a 16x slot (excluding the primary gpu slot) iirc

Hey everyone !

I'm facing a problem with a, ASUS Z270-P mobo, and a SAPPHIRE VEGA 64 graphic card. I've been following closely this tutorial : http://vega.miningguides.com/ and yet, after 2 days of countless installs, BIOS settings, DDU abusing, I just can't get it working. Like not even got close to it.

Not 4, not 6 not 8 of them.

One.

One, only...

Seems like it's the problem comes from the mother board [still in this state of strong denial, that the GPU should go to RMA] and I've only used H81, so far. I'm not familiar with this very Z270-P model, but never expected THAT much difficulty to make it work...

+ Mobo BIOS up-to-date ver.0812 [should I downgade it ?]

+ BIOS Setup :

-----DMI Max Link Speed -> Gen2/Gen3
-----PCIEX16_1 link speed -> Gen 2/Gen3
-----PCI Express Configuration -> Gen 2/Gen3
-----Enabled(above 4G)
-----Few stuff like HD audio disabled, and so on...

+ Fresh W10 install [UEFI]

+ Device manager detects the new hardware

+ Blockchain driver - Inevitably fails with BSOD atikmpag.sys issue [both W7 and W10] before finishing

+ Tried every single PCIe port

+ Changed riser enough times to get pretty confident in the fact that the problem doesn't come from this part

Any help ?

Don't enable 4G encoding unless you've 4 or more cards.
Install GPU1 and drivers.  Do it in safe mode and using DDU.  Reboot into windows normal mode.  Check GPU1 works fine.
Reboot to safe mode on next restart and plugin GPU2 and see if it gets detected in device manager and proceed to normal boot.  test mining/etc.
Proceed in similar way and once you've 4th card plugged in enable 4G encoding while booting.

Nope, didn't work, already tried that. Despite all my efforts not to let it go, I've decided to send it to RMA... 4 to 8 weeks to wait...

I've been using Z270P from past 6 months mining with 8x1060's.

Its been running ON with no issues so far, if you ask me whether I recommend? I would definitely recommend for small rig holders to run 8 or less than 8 cards.

I use Ubuntu (nvOC) which comes with all the miners pre-loaded, so far less down time. I used all the settings suggested by this topic let me run 8 cards straight away with out any hiccups.

Thanks to all that contributed to this thread.  I was stuck on 3 cards for a while. 

im newbie here ,
i have this motherboard too ,
and running 6 x 1060 3gb on it  ( i up to 8 this week )

any one doing it ?

feedback ? probleme ? config ?
i think up to 11 next month when i recive adaptater ( aliexpress 3 weeks) ...
( im 525w with 6 1060 card and power supply is 1000w , that's why i up to 8 )

mb + cpu = 75w
525 - 75 = 450 w
450w / 6 ( 1060 card ) = 75w / each ( 1060 @ 65% core  power limit + OC )

75w x 11 =825w  + mb 75 = 900 watt     im good with my 1000w power supply

I'm also having issues with my Z270-P

I have been able to get 4 cards working, but when I plug in the 5th, I get the Splash Screen for a sec and then it fails to boot. I have tried:
1. Swapping to Gen 1's
2. Plugging in 5th -> Disabling 4G -> Reseting and failing to load Win -> Boot to BIOS -> Enable 4G -> Reset
3. Setting DMI Max Link Speed & PCIEX16_1 to "Auto" and PCIe Speed to Gen 1.

None of these worked. I'm beginning to think it might be a cable thing, but I tried every one of the 4 that aren't plugged in into the MoBo and they all have the same result? So I'm not sure. Any advice you can provide is appreciated.

Edit: I should say I can also get any 4 GPU's working in any combination.. But as soon as I add any 5th card in any slot it fails. I can also get to the BIOS fine, but as soon as it tries to boot Win10, it fails.

i am also sitting on my ass with 4 gpu installed and 2 nice and shinny doing nothing kind of bloody crap setting

Hello everybody,

I had a messy weekend trying to put together a three boards rig.
I have a asus prime z270-p with i3 3.9Ghz 7th gen. 8GB DDR4 2133 Crucial
I bought 2 x 1060 Asus dual OC and 1x 1080ti MSI Armor 11GB.
120GB ssd.
I also bought 6 risers pcie
1000w Corsair power source.


I installed win 10 x64 pro couple of times and tried with the original drivers, last nvidia drivers, GeForce experience updates,  activated 4G, deactivate it, used all Gen 1,2,3 incrementally.
I used the onboard intel GPU, I installed without it and with it. I used the risers and eventually tried without them directly on 16x pci full slots with two card.

I deactivate the Intel GPU and tried to add the boards in successive reboots as well.

The best I am getting is either I install only one board and the rest if I manage to make them apear are dimmed (error 45, hardware disconnected ).

I powered all of them with attention, changed the reiser power from sata directly to the 6 pin power source plug.

I sincerely don't see how to solve the issue. The video boards work individually but it seems I can not make them work together.

Is something I am doing wrong?

I am on the verge of throwing the rig on the window :)

Any advice will be more then welcomed.

Thank you!

i got it here ,

you have to change all pcie to gen 2
and désactivate sound / music card

after plug grafic card 1 by one & boot.

95% of the probleme is from riser , here i got 1 plug ( PCIE to USB ) the small one , are defect
i have try many time to find the probleme.

when one more card dont detected , just unplug usb from rise ( on grafic card side )  to new one card to see the probleme

card , riser from grafic card ,and pcie slot on mother board.
process by elimination.

step by step card by card ( riser by riser ...)

My God I'm having a hell of a time to get the M.2_1 to work. I've ruled out bad USB or bad riser components. I'm going to try the "screw & bend" technique after I clean up the M.2 card's contacts. Note that I'm also using DeoxIT chem treatment on the contacts. Otherwise my Asus Z270-P is running seven 1060 SC 3GB's just fine.

I need to vent this out to my mining brothers and sisters: I just got my second rig online yesterday. I had SEVEN (7) bad riser kits. Yes, one entire Mintcell Version 7 (blue cord) bag of six kits was bad and one other kit was bad. I am so pissed. I wasted several HOURS of time trying to figure this out. I'm glad I ordered Version 8 (red cord) and have more coming. If you are stocking up on risers for future rigs, TEST THEM ASAP so you can return them.

After hours of scouring internet anecdotes and my own experience, I am strongly convinced that 75% of the "can't get more than XX GPU's to recognize" is due to junk riser kits. It is amazing how far quality control can go in a factory. I am blown away that they don't even bother testing their crap before shipping it off. A $10,000 test rig at the factory would avoid $100,000's of dollars in RMA expenses.

Question guys:

mobo : Asus prime Z270-p (ok easy...:))
GPUS : 5 x 1070 4 on 1x to 16 gpu riser and one on Pci16x

I received the last one a slim one yesterday and put it on 16x slot but win10 can't see it! The other four are workin I set enable 4g and put all to gen1.

Will try some of your tricks...and maybe update bios.

Have to look bios version...

Any hints to have a quick solution?

Dear friends

for the last 10 hours i was trying to add 2 extra gpus to my rig.I have 4 rx570 4g nitro plus and i added 2 more .I couldnt make till 1 hour ago.A friend here wrote to disable 4g and restart with only one card (all the others disabled) and then turn off the machine enable 4g and plug the other 5 cards.......IT WORKED!!!!!!!!



Thank u very much

I ahve the latest bios
4g enabled
audio off
Gen to auto

merry Christmas to all , keep mining !!!!

I posted here almost exactly 24hrs ago whining about my M.2_1 not working. Well guess what - after testing each card individually I found the culprit. The issue was yet again a f*cking bad Chinese riser part. Yes, the M.2 cards were 100% fine BUT this time I found a dead Mintcell Ver. 8 riser kit bad. It was the small piece that plugs into the PCI-E and turns it into USB on the motherboard side. I have found three bad pieces like that now! (two Mintcell ver. 7 and now now Mintcell ver. 8).

My hypothesis that all of these "I can only get four cards work" or "I can't get the M.2 risers to work" blah blah blah are all attributed to rubbish chinese riser parts. I can't even imagine how much time has been wasted because those as*holes couldn't do any QC on their junk. It was very suspicious in my mind that so many people have 8+ cards on their Z270-P's yet a select few of us can't get anything to work.

Well there you have it - VERIFY 100% THAT YOUR RISER KITS ARE COMPLETELY OPERATIONAL INCLUDING THE USB CABLE, THE PCI-E TO USB ADAPTER, AND THE PCIE BOARD ARE GOOD.

Yea! Risers and USB connectors between MoBo and riser often become vulnerability. Also the signal attenuation in too long USB cable can affect on rig stability. Even if the OS properly detected all GPUs a piece of .... USB cable can corrupt whole situation

That's why it's always best to plug 1 or 2 cards and test out. If you start with 8 cards in one go you will have hard time troubleshooting.

One would think some chinese engineers could make up some sort of tester for at least the usb cables and the little pci-e to usb chips. I didn't see any IC's on the little pci-e to usb chip thingy so it should be very easy to make a tester for that. The actual cards would be more intensive to test but the cables and chip cards should be easy...

Anyone run into an issue where the power on after power is loss then restored won't work? LEDs come on, but board won't boot unless I short pins.

Hi Guys;

I jut joined week before, and i'm ok for the now. But ı got a problem. I'm minnig with 6 cards. But one of the pci-e x1 ( the top one, the nearest to the cpu, doesn't response. The card is brand new, andi couldnt manage to use it. So ı'm using one of the card with m2 slot.

İs there any configuration about that slot ? Or my mainboard got factory problem ? How can i understand that ?  If ı sent to guarentee it will take min 10-15 days to come back to me.

Is there a way to check if it has a problem or not ? Or any configuration about that ?

spécial thank's to stupid asus to let me save my setting as text file
and no able to load my setting from saved file ..

plug card one by one. ( boot windows each new card & let windows time to install it ....)

many time riser are poor , when u dont see card ,try new riser

For the life of me I can't get past 4 GPU's on this motherboard.  I've tried all the recommendations throughout this thread.

I have confirmed that the GPU's and risers all work fine.  I've plugged them in with different combinations of 4 x GPU's, and they all work.  Just not when a 5th is added.
All GPU's are RX580 8GB's.  All work fine in Windows, up to 4 max.

-Latest ASUS drivers installed.
-Latest BIOS installed.
-4G enabled.
-DMI/PEG/PCIe Speed all set to Gen2.  I've played with many different variations of this.

After the BIOS screen, it just goes black and I can't do anything.

$50 to anyone who has experience with this motherboard, and can troubleshoot and get me up to 6 GPU's.

Change PCIe speeds to Gen1
Disable all Sata ports and USB ports not in use
Ill take Ethereum :P

No dice, same thing.  Thanks though.  Any other suggestions?

Got it working!  Searched around a bit, and some people were suggesting to not use the onboard video, and to connect right to the main GPU for video output.  A few small tweaks later, and it's up and running.

Hi to all
I try to make it work that config
 asus z270-p, 4GB DDR4 2400, 120GB SSD, Intel celeron 3900 + 2x 735W Raidmax PSU + 7x GTX1060 6GB

Everything is fine - win say here are cards, see all 7 of them, but when star miner script it's work 1-2min and start stopping cards one by one. Win10 still see all 7 cards but the mining scrypt none. After restart the same.

Has someone ideas?

I think that it's related to bios version. I have two identical boards Z270-P, one with latest bios version and and with factory 0810 version. Latest version bios I only get 7 working, the 0810 version 8 working exact same setup.

0810 can't be downloaded either from asus support page, strange.

Just want to say thanks. I was struggling to get my 5th card working, but after connecting to the GPU instead of the onboard video it magically started working! 

Guys, I bought two of these boards, but after reading all that I want to ask - what CPU should I buy? Skylake G3900 or Kaby Lake G3930. Or it makes no difference?

I have used G4400 Skylake and now G3930 Kabylake. Can't see any reason why G3900 should not work.

G3900 works fine with Z270-P.

Hey,

I just got my Asus Prime Z270-p to boot With 6 Cards, but it does not recognize the 6th card in Device manager.

In the start i couldent get past 4, but when i Connected one card at the time and Connected the x16 slots last, it booted With 6.

Will update if i find out more.

Anyone got 9 nvidia cards working in windows 10 on this board?

I read this board does 8gpu.  Is anyone have any luck.  Do I need the bios the doesn't seem to be available anymore?

Mine does 9.

And of course you don’t provide any info as to how you got 9 to work, good job on trying to improve the community.

Thank you to all that has provided setting info to your rigs and not “mine does 9

How can I downgrade my bios ? Does anyone have any idea? I already try some ways but none of them worked.

I have several running rigs with 8 GPUs. Most of them with BIOS ver. 0812 and one with 1002. They were also running fine with 0810 (was removed from asus.com when 0812 was released)

I got 6 Cards working now by just unplugging the DVI cable from onboard Graphics.
Placed it in the GPU Connected to main PCI-e x16 lane and it booted With 6 and shows them all.

And of course you haven't read the thread completely.  Cause if you did you would get the info.  Anyways,  It's no settings magic or anything just using a PCIE-1x to 4x multiplier card.  No hassles with pcie to m2 adapters which imo are terrible quality.

Ref: Post #151

guys, which models of power supplies are you using for powering 8 cards on this board? Need to buy power supplies that need no additional cable extenders or splitters to power on rx580

For 8 GPUs you can end up buying a very expensive 1600w or higher but dual psu would be cheaper.

I use 2 x corsair RM850x. It has 3 pcie cables and 6 connectors (150mm distance between connectors).  Has 8 molex connectors for powering risers.
However, you should opt for any cheapest, quality gold rated power supply with 3 pcie cables or higher

Note:  don't blindly go by pcie connector count. (look for the distance between the connectors)  Many times the connectors are closely placed on the cable and you won't be able to use it on adjacent GPU.

Few other recommendations EVGA 1000 GQ, EVGA 850w or higher G2/G3 series

Hello Everyone,

I am new in crypto and trying to build my first rig contains 8x rx570 4gb on z270-p prime but no luck so far.
My issue is that rig doesn't go up with more than 4 cards and constantly rebooting just after show Asus logo (the moment when you can enter to bios). Bios is already set as was adviced earlier in this topic, but still no progress.
There was a moment that I was able to run 6 cards, but after adding another one I was again able to run only four.
So far I made following checks:
   1. Risers - OK
   2. GPU's - OK
   3. PCI-E ports on mobo - OK
   4. Power supply's (2x650 gold) - with 4 cards loaded in windows (no mining) it takes around 100W so should be ok at least for setting them up.
   5. Bios settings - OK - 4g enabled, and Gen1 (also tried different settings of them, but without success).

As rig doesn't even try to load OS my suspicious put on bios version. I think I made a mistake by upgrading it to newest version - 1002.
Now I am wondering if there is possibility to downgrade to 0808? And if so from where I can get this version? Can't find it on Asus website as well as on Internet.

Will highly appreciate any help and advices.

Try this. 
Use only 3 cards plugged into first 3 pcie slots (from cpu end; 1x 16x and 1x in that order).  Disable 4g encoding.  All pcie config to Gen2.  Boot into windows > install drivers for 3 cards
If all good enable 4g encoding and try to boot into windows.  It should work fine.  Install drivers for rest (if auto install not enabled)

Hi guys i have same motherboard z270-p with 5 rx 570 8gb &  1 rx 580 8gb
 ???my problem is that when i boot my rig with 5 cards without connecting riser in 2nd pciex16 slot i can go till desktop, but when i plug in the 6th card in 2nd pciex16 slot it keeps on restarting before i see windows screen or gives a blank screen.
I tried many bios combination from this thread please help will reward  ;)

Try this. 
Boot to BIOS > Disable 4g encoding > Install 3 cards 2 x RX570 and 1 x RX580 with drivers.  RX570 would need atidmag patcher.
Boot to BIOS > Enable 4g encoding > Install rest of RX570.  You would see the dev manager might have market rest of the cards as unsigned.  Sign again with atidmag.

Anyone tried PCI-E 1x 1 to 4 USB 3.0 Extender Riser on this board ?
That would in theory get 11 gpu

thanks for the help guys
I think this thread covers many possible ways to solve the cards issues.
I solved my problem by just connecting the hdmi cable to 2nd pciex16 slot gpu.
Thanks for the help

Thanks a lot for this, but my problem had different root cause. Monitor cable plugged into integrated graphic card!
I was sure that monitor has to be connected to motherboard, but seems its not like that. I found post on another forum where one guy described similar issue and he presented solution where he simply connected his screen to primray GPU (this one plugged into first x16 PCI-E slot from CPU side). Since I did the same my problem was gone :)
I hope it will be usefull for somebody!

This did happen to me where I had to plug in the display cable (DVI) to primary GPU.  However, I am still using integrated GPU and have 9 cards plugged in on the same board after the above mentioned steps.

Here are the steps I took to get 6 gpus instantly working

1. Dont use onboard graphics, use primary graphics card
2. Enable 4G decoding
3. Perform clean install of latest nvidia drivers and reboot

Now WAIT AFTER IT RESTARTS. Hit control+shift+esc to bring up processes. Notice that Nvidia install manager starts running. It ran a total for 6 times for
me, presumably for each card. This takes a while (took 10 mins on mine). It will run in a loop between Nvidia stuff and windows installing.

Then your cards will show up.

If it works would mighty appreciate some coins!

I have a similar issue with this mobo that I can't seem to figure out.

3 GPUs (rx 580 4gb)  run fine, mining eth.

When i add the 4th, it shows as hashing at 0 mh/s and then says it hangs, it restarts the miner and that happens over and over.

I have all my cards attached using risers, none on the mobo itself, just because the physical way it's set up would make that difficult. Does that matter?

I have 4g encoding enabled, i have tried both gen 1 and auto. I uninstalled and re-installed drivers, no dice.

Any ideas?

Ok so first of all try exclude failed GPU's and risers, so:

1. connect only three GPU's, but now change one of those which you are 100% sure that works with the one which you tried to connect at the end. test it.
2. do the same with risers.

and most important: Do all tests with stock bios and clock/voltage settings! Time for OC will come when you finally get some basic stability of your rig.

Hey guys,
(let me 1st say sry for my bad english!)
I have the same issue: when I add 5th card my rig goes to boot loop.
And I did all that was suggested (even disabling 10 USB and 4 SATA connections of my mobo) except installing windows using a UEFI USB, I simply installed it by using DVD.

Anyway I overcame this shirty thing by not using the 16x PCIe slot on my mobo cause if any of my 4 GPUs is connected to 16x slot no matter which slot I use for the 5th card it goes to boot loop.

So right now I have 7 GPUs connected to mobo by skipping the 16x slot and everything is working perfectly. I just can't seem to get what the fork is wrong with my freaking 16x slot!  :-[

BTW I tried Gen1-Gen2 and not Auto configuration but I don't think that is what making the problem.
Any Ideas ??? ???
Thnx

Hey guys,

Same problem but with the last pcie-1x slot. It works when 1 gpu is plugged in the slot but it wont recognize the the card in that slot when there are 7 other gpu's connected. TRIED EVERYTHING, going to flash BIOS 0808 when I can find it. It happend when i updated the bios and when windows updated to version 1709...

Been and still am there! But at least yours boots mine immediately goes to boot loop. As you mentioned yourself problem is software wise, have you tried reinstalling the windows?

BTW if you found the BIOS version could you provide us with a link? Thnx.

Are You guys on windows 7 with those 8th gpu problems? It won't work... You need win10 or linux.

Sure mate Win10 x64 Enterprise

My problem is not 8th GPU: it's the 5th card that makes my rig enter boot loop ONLY when one of those 5 cards is connected to 16x slot!
So if I skip the 16x slot I can add and run 7 cards easy and clean...Weird :-X!

Tried to boot into safe mode with it?  You'll have to force safe boot by booting with your 7 cards and restart with safe mode enabled on next run. 
Force shutdown > plug in 8th card > boot into safe mode (if it works)

For all of u who are struggling as I was with getting GPU recognized. I got 8 RX550 from Sapphire on my Z270-P and I could not get more than 5 gpu recognized.
 
I suspected everything faulty M2, PCI lanes not working, riser not ok, faulty usb cable, bios settings, psu not ok, riser chip problems and so on and on.

At the end I started switching gpu's from non working spots to working spots and vice versa, since independent from position always the same 5 were working and the same three stayed unresponsive.

At the end 3 of the 8 GPU (37,5%) were DOA. I wold not have expected this. Anything but a DOA rate of 37,5 %

As tip don't wait to long for starting to  switch GPU from position, it might save you some time figuring out what is wrong as it would have saved me some time and sleep deprivation.

Hey guys, I've got the h270plus which is pretty much the same.

I've got 7 GPUs working, and manage to isolate the issue to M.2_2 slot.
That's after swapping everything around, m2 riser, gpu, and all.

It doesn't matter if I use GPU as monitor or iGPU, it won't detect the card that's plugged into M.2_2 slot.

When I only have 6 GPUs, I tried one of them on M.2_1 and that works, when I move it to M.2_2 it doesn't work.

So yes, isolate that to M.2_2 slot. Regardless of the number of GPUs.

I have tried all different combination of bios settings, no luck.

This is the type of riser I am using which is M2 to USB 3.0

I think that might be the issue?

All the videos I saw online that runs 8 GPU successfully is using M2 to PCIE

Could that be the issue as one is 16X and the other is 4X? And to do with M.2_2 not able to work with the 16X card?

I've ordered the 4X on eBay and that will take a while to get here.

If anyone else has any insight, please do let me know how you get 8 GPU working.

OP here, so the rig failed after with Z270-p failed after 10 months, first it failed to boot to WIN10, nevermind tried to switch to Simplemining, the OS on the stick got buggered on booting up. I managed to get 5 cards running on windows after a BIOS update to 1002 (plugging them in one after another with reboots). Rig ran for 15 minutes before the graphics failed...oh well Simplemining atempt 2 on the way...

In my opinion the m.2 adapters are not reliable enough (I was using the one similar to 2nd link that you posted).  Also, the build quality are terrible on those.

I had experimented with one and it burnt.  Luckily I was debugging my rig when this incident happened and I could turn off the rig in time.
I am using the below 1x 4x Multiplier adapter and don't use the m.2 to pcie adapter.  I am not sure how many you can plug in on a single board but So far I have tried only 1 MUX.  Each can support 4 cards.  So effectively you get 3 additional pcie slots.

Simplemining on the M.2 drive failed to boot, simplemining on SSD failed to boot, re-installed windows and I'm unable to even install drivers for graphics card...oh well of to the RMA land it goes...  ;D

Thanks for your input, may I know when you are using that m.2 adapter that burnt up did you connect a cord to the floppy socket on the m.2 adapter?

I've also ordered a PCIE 1 to 2 adapter, slightly cheaper.

May I know how many cards do you have in total for the rig?

yes it was powered through that.  Molex-floppy adapter.  However, even the gold fingers that go into the m.2 adapter were off.  I had to fiddle/nudge a little to make them recognizable.  I only used one and was done with it.

Have you disabled fast boot on both BIOS and Windows?


I have read that you are not supposed to connect the molex-floppy thing if you are using powered riser. That is meant of the older design of riser which is not powered.

i have the same board and everything pretty much worked out of the box for me.

updated BIOS
set 4g decoding enabled
set m.2 to pcie
pcie link speed to gen2

both m.2 slots and all 6 pcie slots work fine.

im using these m.2 adapters: https://www.amazon.com/gp/product/B074Z5YKXJ/
im NOT using the power connections as they are not needed

if you've isolated your problem to a single m.2 slot then the board is likely defective, i didnt have any issue like that, it just works. RMA time.

Perhaps.  But mine wasn't getting detected unless it was powered

Might want to reset your BIOS configurations and start again?
From experience, after booting past the logo, the screen will go dark and shows no signal detected for a while, can be quite a while, before it lit up again and launch into windows. But if you get the reboot loop, might want to reset Bios and start again.
I hope not. But I've lined up a few options. Will know when the components arrive ;)

After a 2 long hours I finally was able to make this board work with 8x 1080ti!

I’m on phone right now but if anyone wants my config let me know!

From my observation, having the monitor plugged in to GPU doesn't affect the hash rate.
I set the windows to turn the screen off automatically after 1 minute.
I also switch the monitor off on the wall when not using.
