Hi

I saw this motherboard and i was interested in getting it as an upgrade for my gaming/mining rig, the idea is to install 5/6 graphics,  looks like it should be able to support all of them using Pci X1 + X16 + M2 . Now i want to know if could exist any issue related with the chipset or the PCIe lanes. I searched for info related to this motherboard on the internet or people that could have the same one and be using it for mining but I have not found anything so far.

Any idea if it will work?

Looks like it should.  May need an M.2 to PCIe adapter to get the 6th.  Googled a block diagram and can see 3 of the lower chip and 2 off the primary then 1 off M.2. Or you can use a 1x4 splitter on primary or secondary...should be fine but will depend on the bios control options for slots.

YMMV

i have this board on my one rig. works great. full of 580 cards all mining at 30 plus hashes.
i have a 3900x in it and mines monero with 23 threads.
even have a m.2 ssd all working great.
probably the best board i have minus a new b550 i have yet to hook up as i buy things when they go on sale.

Awesome ! just out of curiosity , how many GPUs  do you have working on it?

I had everyone filled.  That was using risers because my cards are to thick to put side by side.

You will also want to use risers because this motherboard does not have supplimental power for pcie bus like some mining boards.  Riser prevent bad things from happening.  👍

I have this MOBO but when I use all 3 pcie x16 slots, I dont get any GPU output.
I am using Ryzen without VEGA and have 2x 3080 and 1x 3060ti

Do you think that using risers pcie x1 helps ?

Or do you have some custom bios ?

Yes try risers your motherboards pcie bus is probably overloaded with 3 physical gpus plugged in.  you can run them all on risers which is much easier on the motherboard.

The Asus Rog B450 is an AMD motherboard, it's a big no for me because intel motherboard works better for me, I have two AMD asus motherboard and 4 intel motherboard but the AMD motherboard gives me problem often, sometimes the AMD will only recognise 3 gpu of out of four and I'm using riser for the graphics card, always a pain in the ass, better buy an Intel motherboard

Hi, got a mining rig with

* Asus ROG STRIX B450 (https://rog.asus.com/motherboards/rog-strix/rog-strix-b450-f-gaming-model/)
* 2 x Gigabyte RX5700 XT
* 2 x PCI-E 16x to 1x risers (https://www.newegg.com/corn-electronics-model-ver006c-riser-card/p/17Z-00AP-00013)
* Ubuntu 20.04 with kernel 5.4.0-42-generic
* amdgpu pro drivers 20.45
* ethminer 0.18, but also tested with nanominer. Same problem


---

* 1st 5700 is connected to the 1st PCI-e 16x through a 1x to 16x riser
* 2nd 5700 is connected to the 1st PCI-e 1x (above the 1st PCI-e 16x) through a 1x to 16x riser

So, lspci detects both cards (plus the integrated video controller)

As ethminer does



Just the 1st 5700 shows a rate of ~47MH/s, the second one keeps at 0.

* Logs for the 1st 5700: https://pastebin.com/66RZMymy
* Logs for the 2nd 5700: https://pastebin.com/iaraAbd0

We tried:

* Forcing the video to output from the bios to the motherboard, then leaving it to automatic (hence the video comes from the 1st 5700 on the PCI-e 16x)
* Replaced risers
* Using different mining software as well as different mining pools
* Connecting an HDMI monitor to the onboard graphics, to the first video card and the second video card. Same problem on three cases. Both 5700 detected, just the first one mining. Video is OK on three video cards.

I've noticed that clinfo hangs during the 2nd card information fetch, log here: https://pastebin.com/T5Fmaast. It hangs just there


Thanks in advance

Asus ROG B450-f is too high for mining, as a miner you need to cut expenses down by all means, the main mining power is the GPU, I'd rather get cheaper motherboard for mining purpose only but if you are a hardcore gamer then it's a good buy

Hi waywoos!!! sorry for the interruption. First of all english is not my natural language, sorry if I have some errors in my writing.
I have recently build my first rig with a Asus Rog Strix B450-f Gaming and I'm having a lots of troubles; I saw in this post that you have the same board and don´t have any problems. Can you share with me your bios settings? or tell me what modifications did yo do on it.

My setup is:
Asus Rog Strix B450-f Gaming
AMD ryzen 5 2600
4 MSI rx5700 MECH OC (non XT)
4 pci-e powered risers
8 GB DDR4 RAM
HIVEOS as operating system

The main problems that I have are:
1) The motherboard doesn't boot if I don't put a video card directly to it (without riser) so... I can't put all the GPUs with risers.
2) The second is that from time to time a GPU disappear and  I'm seeing a lot of "GPU errors" in the screen

Sometimes the rig works good for 2 or 3 hours but after that problems begins... and sometime errors appears after 15 minutes of operations
I've test with different risers and only connecting 2 GPUs and switching them to test the graphics cards to but the are working well.
I've updated the motherboard bios too.
In bios I've enabled 4g decoding and set PCIe to gen2 (I've also try gen1 and auto)

Thanks in advance

My board is full of 570 and 580s.  Only the one top pci do I put the card directly on the board.  The rest I use risers powered by a 1200w power supply. I do that so I have video to my monitor.  
I would suggest you not over clock so high.  Bring them down and see if it gets better.  I had the latest bios as well. Think my settings are 1200 and 2150 roughly. Undervolted differently per card. All modded. Using blockchain drivers.
Because I’m running Polaris I’m using 5.1c.   Not sure what else to tell you.  Mine runs a month at a time with no problems.  Maybe try to find the problem. Is the 5700xt modded? Mine are modded
On my asrock board I use 2 5700xt and they would shut down several times a day.  Found the problem was I was using 1330 for clock.(I think of hand)  I backed it down 20 or so and been smooth sailing.
Because you are only running 8 fb ram maybe try adding virtual memory as well.
Are the risers new?

 Does anybody got 6 GPUs on Rog Strix B540-F ? (I mean without using M2-> PCIe converter). Thanks !

Use newer driver and newer miner version. Blockchain driver is very outdated and not needed.


Yes, why not? There is nothing special on this mobo

Hello fellow miners! I'm kinda newbie to this mining universe, although I have a lot of experience in the world of computer hardware. We were using the Intel chipset for the platforms and there was no problem ... but we recently bought an Asus Rog Strix B450-f, to fall in love with the AMD product again, but we ran into a problem trying to fill all available pci slots. .... right now we have 4 RX5700XT connected with 1x risers. All good. but when we try to use the 16x slots with risers the hiveos do not detect any cards. Curiosity ... those 4 video cards will work in any pci slot (with risers, right) but the first 2 PCI-e 16x (the ones with the silver border). I'm sure this is a configuration issue, but I haven't had time to explore the BIOS too much ... if someone can give me some advice on the configuration ... it will be greatly appreciated. Our goal is to complete this rig with 6 video card conected with risers as we do with the Asus prime Z390.
Thanks a lot to anyone who can throw a bone to this old argentinian dog!

Asus B450 motherboard is good for gamers that want to use crossfire setup for gaming massive monitors at once but kinda too costly for mining rig builders, at the price you can get a higher motherboard strictly for mining that has many slots 12 slots  or even 16 slots

unfortunately in Argentina there are not too many options to choose for motherboards.... and due to the recent eth increase, nearly mining-class hardware is getting really difficult to acquire.... snif....snif.... :(

Hi sxemini.

I'm facing an issue with oc/uc my modded RX580's , which I can do only with Beta Blockchain drivers. Thread opened here: https://bitcointalk.org/index.php?topic=5312692.0
With any other driver, oc/uc values are set back to bios stock values as it was forgiven to modify them.
Any idea?

Can you share your BIOS Version and settings?

I have this board and I cannot get it to post more than 1 GPU on risers.

General setup for AMD bios for mining

    set IOMMU to ENABLE.
    set VIRTUALIZATION (C1E) to DISABLE.
    set POWER CONTROL (SVM) to DISABLE.
    set CPU UNLOCK to ENABLE (this may prevent CPU temp from being read properly).
    set COOL AND QUIET to DISABLE.
    set CPU CORE CONTROL equal to the amount of CORES PER PROCESSOR for your particular CPU make/model.
    set ONBOARD AUDIO/SOUND (AZALIA) to DISABLE.
    set IEEE1394 to DISABLE.
    set CPU FREQUENCY SCALING to DISABLE.
    set CPU PERFORMANCE MODE to ENABLE.
    set FAST BOOT to DISABLE.

waywoos! is it possible to share your bios settings, im strugglin with my MB, tried all so far as i can find on internet! ive got 4g enabled, and fastboot disabled and gen2, but i might miss out on some pciex settings!

regards
kenron

i didnt touch a single thing in the bios. just have the latest bios.
left it all alone minus i overclocked slightly for  my 3900x so i can mine monero on 23 threads at the same time.
i even have a m.2 nvme hd attached to the board.
not sure what you are struggling for. i even cleared with cmos before after failed oc attempts.
do you have added virtual memory?
performance power settings?
those are really only things i change with windows.

thnx for reply, ive tried with one card and riser and miner works fine ( yes ive adjusted VM) , when i try the other card that also works fine, but when i try both with risers i get a colorful pixel picture on my screen. ive updated bios and i get the colorpixelsscreen both with default bios setting and with pcie gen2, and 4G enabled. so i know that risers work, cards work, but not together ....  ??? ???

Put the video card in the biggest top slot.  Use that for monitor. Put the riser on various small pci slots.

ok i will try that, thnx  ;D

hey waywoos, i got a reply from asus who said i the motherboard wasnt made for mining and that i couldt use the smallest ports for risers  ??? ::) do u use one card in main graphicsport and the rest with risers? My motherboard is ASUS ROG STRIX B450-f Gaming 2, might there be a differense with ASUS ROG STRIX B450-f Gaming  and ASUS ROG STRIX B450-f Gaming 2?

It’s not a mining board.  Those small ones work.  Have used my board for over a year and probably least amount of downtime on my boards. Use the small ports.

i tried your suggestion with one gpu in mainslot and 1 card with riser in a small slot, but i still gets  this https://i.pinimg.com/originals/8d/4a/42/8d4a42a02545d49fd3393903d71bebed.jpg][url]https://i.pinimg.com/originals/8d/4a/42/8d4a42a02545d49fd3393903d71bebed.jpg (http://[url)[/url]

cant paste pic, but u know the tv colorpixelsheit when somethings wrong  :-\ :-\

i had this before on a few boards.  is it flashing ?

if so you need to find a way that you can ddu the drivers and then reinstall them.
something went corrupt.
i was able to get into my system with teamviewer before when my screen was flashing and pixeled.
perhaps its your card not the board.
or if you have a old video card say like a vga one try that.
i have a rage 512 that i use for situations like that.

thnx, wll try :-)

I have several of these motherboards. They are my go to board. I don't like to build rigs larger than 6 GPUs, but I have tested and can run all 6 PCIe slots and 2x M.2 with adapters.

ty, all 6 cards working! had to enable 4g, pciex raid and disable fast boot

 :)

fookin shit, had to turn off power because of an eletrician, and when rebooting problem was back! should pciex16_3 control be put at 1X or 4X maybe?

you get the blinking screen thing?

yes, same sheit that earlier,  ::) but with same settings that got it to work properly

Im running same board, 3060 ti, vega 56 and 1660 super.
After BIOS update, disabling fast boot, enabling pciex RAID and using gen 2, I was able to boot with one card on mobo, and two with risers. But then all cards are running only about half the speed they should....

With 3060ti mobo, and vega 56 riser I get about 95MH/s
With 3060ti mobo, vega 56 with riser and 1660 super with riser I get total of 70 MH/s. So something is limiting the hashrate terribly....

Both risers tested separately and they work. Any ideas what to test next?

Any Ideas?


Now I tested same setup but with different mobo. Same results  ???

Could it be the PSU... Im powering risers with molex to 6pin adapters. Maybe the PSU has problems when it needs to power two risers at the same time?

hi guys,

your tips have worked wonderfully.
I have been running 6 cards for 2 weeks without any problems.

Have any of you already tested 8 cards?
So 6x Pci-e + 2x m.2 interface.
I already have the m.2 to pci-e adapters, just waiting for the cards.

 
If so, how must the BIOS be set?

Thanks already

Hi there! I am writing to you from Argentina! Help here !!! I have an AM4 - Asus Rog Strix B450-F GAMING II with 4 gpu RX570 8gb. With a GPU everything is fine. When I add the other 3 the mother does not work. Take everything out, try 2 and the same does not start. I already put everything in Gen2 and gen1. Test GPUs with raisers and onboard. I flashed the bios, tried different slots and nothing ... there is no way. Now I get a video error, I see vertical stripes, when testing with 2 but the motherboard does not start. Several tell me that it is a bios configuration issue but what I tried did not work for me. what dou you recommend?

Hello everyone.
I have 2* 3090 running on riser, when i want to add the 3d one i have à Black screen when powering and no signal is détected on the screen. I need do a cmos and run 2 only cards.
I use à AMD athlon 3000g as processor ( very low watt consumption)
Any one have an idea of what is going on ? How can you guys run more then 2 gpu on this motherboard ?
