what problem were you having? Mine works fine for a couple hours then locks up on desktop. Can't move mouse, rdp, nicehash disconnects.. i have to reset it... works a few hours then same thing again
We have not encountered the lockup issues ourself when testing. Can you let me know what PSU and GPU's you are running?
You can also try changing the following settings in BIOS :
Bios > Advanced tab > CSM configuration > set CSM to disabled > Back to top level of bios > Chipset tab > North Bridge Configuration > Graphics Configuration > Aperature Size > Set to 2048 > Save and reboot
Let me know of the results.
for me, I was using 1080tis with the octominer ATX psu. I first installed Windows with just 1 card installed and everything was fine. installed a couple more cards, everything was good. then when I tried with 4 or 5 1080ti's and a 1050ti, windows was having trouble. first it wouldn't recognize the additional cards. then after a lot of reboots and re-installing nvidia drivers I managed to get it to see all 6 cards but windows was busted - when it booted it would just flicker the screen off and on roughly every 1 second, and any application or program you open would disappear when the screen blanked.
so then I thought windows was just trying to initialize all the cards and drivers so I let it sit like that for an hour and came back and it was still just flickering and unusable. I tried re-installing windows several times, same results. gave up and moved on to HiveOS, and I have had zero problems since.
