Hey guys
Did you have any luck getting a 9th GPU to be detected on the Asus prime Z270-A mobo?
My mobo is currently quite stable running 8 GPU's using one powered M2 adapter, I recently installed another powered M.2 adapter on the second M.2 slot and I can't get the system to detect my 9th GPU
I remember when i installed my first M.2 there was a message after the BIOS screen before Windows loaded indicating that the system detected an M.2 device, when I installed the second M.2 I never had that
I have already configured both M.2 ports on the BIOS for PCI-E use
Any feedback is appreciated

Which Windows OS are you running? I know that you should not have any issue getting the 9th card to show with your favorite Linux distro. You could try to do an in place upgrade with the media creator tool if on Windows 10. I have had luck with getting several extra cards detected afterwards. But honestly I think 9 GPUs is pushing it in any Windows OS.

Just curious, did you have any issues getting the mobo to run fine with a riser in the main x16 slot? I have the Z270-P and I can't get it to run with a card attached to the PCIEX16_1 with a riser. I tried it with just 3 cards and it would only detect 2 cards, however I'm running 5 cards just fine by skipping that slot.

I got 3 rigs with PRIME Z270-A mobos, and they all have 9 GPUs (2 are 9x1080Ti and 1 is 9x1070). I have run all 3 rigs on both Windows (latest fall edition) as well as nvOC. No problems with either. This is how I have my BIOS configured on these rigs: Advanced/Platform Misc Configuration - Everything Disabled Advanced/System Agent (SA) Configuration/Graphics Configuration/Leave alone Advanced/System Agent (SA) Configuration/Graphics Configuration/DMI/OPI Configuration / DMI Max Link Speed = Gen2 Advanced/System Agent (SA) Configuration/Graphics Configuration/PEG Port Configuration / Gen2, Gen2, Auto Advanced/PCH Configuration/PCI Express Configuration/Gen2 Advanced/PCH-FW Configuration/PTT Configuration/PTP aware OS = Not PTP Aware Advanced/Onboard Devices Configuration/HD Audio Controller = Disabled Advanced/Onboard Devices Configuration/M.2_1 Configuration = Auto Advanced/Onboard Devices Configuration/M.2_2 Bandwidth Configuration = X2 Advanced/Onboard Devices Configuration/RGB LED Lighting/In Sleep, hibernate and soft off states = Off Advanced/APM Configuration/Restore AC Power Loss = Power On Boot/Above 4G Decoding = Enabled Boot/Secure Boot/Key Management/Clear Secure Boot Keys = YES
Hope that helps.

I'm using Windows 10 with latest fall creator update 1709, this version is supposed to support more than 8 GPU's

All three PCIEX16 are working ok with risers, never had any issue with it, though I previously had to RMA a similar mobo as I had a PCIEX1 slot not working at all

Also make sure your M.2-to-PCIe adapter board is properly aligned with M.2 connector. May need to move a bit either side.

Supposed, but apparently it still doesn`t support more than 8 of same cards. As soon as I plugged in 9th 1080, it all went to shit, blue screen, freezings, nothing works. After I removed 9th, problems stayed
