ASUS Prime Z270A with 7 GPU

[mimk97]

Hi,
have anyone this Board working with 7 GPU (RX480) ?

[BitcoinBabbler]

Why do you need this anyway? Why don't you Craigslist?

[mimk97]

Craigslist?

[andrewaka]

everything works fine

[cryptotore]

I've got a build with the ASUS Prime Z270-P coming up, will test with 6 cards!
Might try with 7 if I can get a m.2 to PCIe adapter

[mimk97]

everything works fine

4G enabled
All Cards are recognized. but SSD extreme slow

I'm fairly new to this so please go kind on me...

I have the 270A pro and MSI 570 gaming cards (and an M2 SSD)

Once 4G enabled it works fine with 4 GPUs, boots up with 5 with issues (slow to detect) and 6th card in it crashes (BSOD).

I wonder if it's a bios setting I have to change or disable USB3 ports or something for it to be able to handle it.

I think that is the 17.4.3 driver because I have the msi z170A pro carbon and same problem

i read that you may be only able to use 5 of the rx 500 series gpus in a rig (on any mobo)

Thanks for this shocking news. Do you have a reference?

Once 4G enabled it works fine with 4 GPUs, boots up with 5 with issues (slow to detect) and 6th card in it crashes (BSOD).

I have exact same problem, 17.4.3 drivers, z270 chipset. When i plug 6th card in it crashes reboots. In theory flashing rx570 with rx470 bios should allow to use older drivers and run more cards.

I dont get i work with 7 GPU.
I enabled 4G and Generation 2 in the BIOS. No changes else
Only get 4 to work.

My Hardware
7x RX480 8 GB
7x Powered Riser
Asus Prime Z270-a
8GB RAM
60GB SSD Sata3
Windows 10 Pro
AMD Driver 16.11.5

Any idea? Is it working only under Ubuntu?
Help very recommended?

I use this mb with 8 gpu card (480), must enable 4g, i use also gen3 but also gen1 or auto working.
On window you must install in EUFI mode or not work with +6 gpu. Rember to use old amd driver without signature check cause if you try to patch it cause you are in eufi mode window will crash on startup.

On simpleminingOs you don't have problem, it will consume more power less hash rate but work easy.

Hi! Can you please help me. I dont know why my asus prime z270-a doesnt have 4g enable even i already ipdate to the latest version of the bios? Do i need to remove all gpu so the 4g will appear?
Thank you!

Install 16.12.2 driver. This help me run RX480x6 cards on Z170A pro carbon.

Hi. Did you enable your 4g? Or you didint change any in bios? Thank you!

Manual setup BIOS here - http://mining-hardware.weebly.com/blog/msi-z170a-with-skylake-cpu-bios-mod-tolud-6-gpu-success-step-by-step
I use last original BIOS from MSI without change in file + "Above 4G Decoding" enabled.
4 ASUS RX480 8GB + 2 MSI RX480 8GB work fine.
With 17.5.1 work only 5 cards. 5 + 1 card = BSOD.
With 16.12.2 all work stable without problem.
Use Display Driver Uninstaller (DDU) in Safe Mode before install driver.
My OS - Windows 10 x64 UEFI boot.

what a huge pain in the ass! 
 
thanks for posting though, for others with this motherboard

The board will easily do 6 RX 5xx cards

My question is how do I get it to run the 7th card? 6 is easy peasy. Add the 7th card and nothing..............I mean NOTHING!. Even with an EVGA 1600 T2 or using an EVGA 1300 paired properly with an EVGA 1000, I get the same result................nothing. I mean the PSU appears dead. The CPU fan won't even spin at power up, and it dam well won't POST. It simply appears like the PSU is dead. Remove the 7th card and the system fires back up and works normally mining on 6. Using two risers per sata port on the PSU. I've tried moving risers around, swapping them out(I have a sack of 50 new version 6-7. They said to be 6, but many are 7) Nothing works. Tested and working risers connected in any order onto the mobo works up to 6 cards. Add the 7th and you get what appears to be a dead PSU. I'm fucking baffled.

I made an nvOC image which supports 8x nvidia GPUs with this mobo using an m2 adapter.
