I just got one of these and am having lots of issues.
Windows 10 latest creator
AMD blockchain drivers
latest bios for board
all powered risers (electric tape on back to keep them from shorting) (why did they build this board with slots so close?)
Ok so I did all the normal methods for getting multiple GPU's to work on Windows.
I had 8 cards up and running a few days ago.
Then my surge suppressor went out.
3 days later the most I can get is 7 cards and that was a real struggle.
If I take each card by itself, DDU,reload drivers, Patch, it will run just fine. So I know my GPUS are fine.
If I take one at a time and let Windows load driver and then patch driver and reboot I can get (usually) 1 then 2 then 3 then 4 then it gets very sketchy and hit or miss.
I am using 3 PSU's to spread power around so plenty of that. (3 because I planned on adding more cards)
In the bios all I have done is disable onboard LAN (using wifi) disable onboard sound. I have tried PCIE auto, gen1 and gen 2. Honestly I dont see any difference. Same results I mean.
During the last 3 days I have probably tried everything a person could try to get back to 8 cards.
Here is what I know -
All 8 cards will mine
All 13 slots have been tested successfully
All drivers and updates are done
Windows sucks
So I tried Linux. Linux also does not see all cards. This implies a board issue or a bios issue.
Any suggestions are welcome and maybe someone has an idea I havent tried.
I think because of that AMD blockchain drivers. You need to use lastest driver.
Yesterday I got all 8 cards recognized and working. It was just luck I think. I changed the GPU in the primary slot and set the slot to Gen3.
Sometime last night the rig rebooted. Now I am back to 7 cards.
EDIT***
Ok made a change and things are looking good.
All slots now at Gen1 except primary GPU slot which is Gen3
With this change all 8 cards are running and SGMiner is no longer having the insufficient memory issue.
I caught NewEggs Black Friday sale so I have 5 more 570's on the way.
Will report after I get them all in, modded and running...
