ASUS Prime Z270-A Help

[architectonik]

Hey All, I need some help.

Using an ASUS Prime Z270-A mobo and attempting to expand to 7 cards.

I have the 7th card in, but I get error code 43: "Windows has stopped this device because it has reported problems. (Code 43)" on any card connected to PCIEX1_4

I think it has something to do with the PCIEX1_4 slot because each card works in every other slot but that one. 

I don't think it's a riser or gpu problem because each works great in a different slot except PCIEX1_4.

Has anyone come across this before? Do i have to do something to the motherboard? There is the SLI Bridge that came with the MOBO as well, do i use that? Do i need to reset my virtual memory maybe?

Thanks in advance and any advice is greatly appreciated.

I think i need M.2 to PCIE adapters.

This MoBo supports 8 GPU with no issues.
You just need to setup BIOS: update to the latest version and Enabling 4G encoding.
Even at youtube there is videos howto setup this MoBo

This is pretty accurate.  I have one of these boards; and I never had any issues with any of the PCIE slots.  The only time was when I was trying to have too many onboard devices and too many GPU at the same time.

Try the above;  and try just a primary GPU in that slot with nothing else (1x-16x riser necessary)

already done....BIOS are updated per several youtube videos

I think i need the adapters

I think you are using windows 7, change to windows 10 will fix it.

Just test it with one card installed in that problematic PCI-e slot.
If it didn't work either, chances that it isn't the BIOS nor the OS is high, one busted/defective PCI-e slot isn't really news.

BTW, you'll only needing the SLI bridge if you're using the board for Gaming and other Graphic-intensive Applications.

Chances I think are high that the specific Pciex slot is defective if you tried everything else from the replies above. It is an easy fix though in a computer repair shop if that slot is only slightly damaged which in the majority of the cases is true from my IT experience.

This board supports 8 cards without problems and is one of the best for mining.

I already used this motherboard with 11 AMD gpus, with all the m.2 to pcie adapters and a splitter but could go up to 12 gpus with no problem.
The thing is, I was using HiveOS with any problem, never tried on windows

Is there a work around for windows 7 to get more than 6 cards working? I already attempted the 6xGPU Mod with no luck.

I have ruled out any hardware issues.

all pci-e t0 Gen2 and enable 4G encoding.

Some pci-e settings in BIOS are located at strange place - in boot menu ))

We could run 7 cards with some mods in windows 7 but it isn't stable. You should upgrade to windows 10 and run 8 cards with this mother board.

When going to Win10, was there a difference in hashrate for you with the same cards?

Hashrate is the same but the error Code 43 will never come back

I have 12 GPUs under Windows 10 LTSB on z270a with no problems (M2 and 1 to 3 GPU adapters from Aliexpress are used)

[architectonik]

12 cards is very impressive. What PSUs are you using with 12 cards? NVidia gpus?

[RuMiner]

PSU IBM DPS-2500BB or DPS-200BB on most of my rigs

Could you post a photo of your rig? How you placed 12GPUs and how you make a maintenance? Dust removing etc.?
Also cooling system of the rig is interesting

don't have a good photo, just CCTV image for now (clickable). it is a classic layout aluminium 8-GPU rig plus 4 cards from the side nearest to PCIE slots. metal shelfs are transparent for easy maintenance, dust removing using air blower. standard onboard GPU coolers, nothing special. narrow room has forced air flow about 6000 m3/hour per ~9kW of rigs.

Oh yeah! Almost useless rigs now )) Guess they are 3gb and 4gb card version )) And with weak celeron cpu which cannot hold grin with all of them ))
