Hi @stas3, I’ve made a build mostly following your build.
We’ve got it to POST, using a 1050ti as 2nd GPU, and managed to install ubuntu 20.04, but it doesn’t detect the A100. Can you share how you installed drivers etc.? Did it just detect everything out of the box?
I only see a couple of obvious differences so far.
BIOS
IGPU Multi-Monitor: Disabled
I don’t find this option anywhere in the BIOS. I’m on BIOS version 1402.
Would you mind sharing your full mobo settings? With a usb formatted to FAT, you can save a txt file with your settings in the BIOS, under
Tool > Profile > Load/Save profile from/to USB
I’d very much appreciate it.
Cooling
At the moment we just slapped on a 3000 rpm noctua fan to a duct (see Linus Tech Tips), and we can definitely feel the heat venting out of it.
According to this post, the A100 can be quite sensitive to overheating and auto-shutoff if it gets too hot… did you have any problems before getting your water-cooling system set up?
The CPU/mobo temperatures all seem quite reasonable, so I’d be surprised if this were the issue, but…
My BIOS settings, in case you’re curious (screenshots + txt file)
