Asus prime Z270-p

[shadow1975]

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.

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 ?

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?

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.

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?

[Marvell1]

the other 2 cards are  both 1070 rigs , this is my  first 1060 rig . Im attempting to make it  8 card with  the m.2  but  just want to get  to 6 cards before i attempt  8 !  4 cards running  like a  dream  but  just no luck once the 5th card hits the board , constant boot loop. will update all the drivers  now and post an update  shorty

 and so beings the 10th hour of  rig  fiddling  

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...

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.

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
