Nvidia GPUs tested: 750ti and 1060. These don’t work good with KCMA-D8. You can get them to work if you disable nouveau drivers, but then what’s the point? I think nouveau had problems with vesa handover or something. Both nvidia cards did work on qubes with a different mobo on a standard bios. Popped in an AMD GPU for KCMA-D8 and it works great.
Has issues with sys-usb not seeing usb controllers randomly. Currently using a ps/2 keyboard and usb mouse. I just reboot or try moving the mouse to a different usb port when it doesn’t work. Mouse seems to work reliably with an external usb hub, but I only just started using it.
Setting the displays for “quick power off in blank only mode” under screensaver settings really cut down on the heat generated while leaving the computer to run overnight.
Energy consumption can vary greatly depending on the processors used. The ones I’m running are 95 watt processors and I’m running two of them. You can just run one of them and put a piece of plastic over the unused processor socket. There are lots of processor options out there. See: list of Opteron processors. Try finding a wattage that works for you. Libreboot for KCMA-D8 currently compatible with 4200 and 4300 series CPUs. See Libreboot. NOTE: KCMA-D8 currently unsupported by libreboot. Just download the older version of libreboot. See: Libreboot Bios download.
Computer got stuck at “loading initram” on powerup. Rebooted and works fine. This happens very rarely. On another note the USB hub still works great, still no usb mouse issues while using it. I’m using this usb hub. I don’t use the external power adapter for the hub.
Thanks for all this info. I came to this thread by searching for memory compatibility of this board. What memory modules are you using? All the same or different?
I don’t touch sleep mode because it doesn’t work. Computer boots fine about 95% of the time. It’s rock solid once it’s up and running. What problems are you having with yours?
