Use your IGPU and test each pcie slot individually to see if you just have faulty pcie slots.

Interesting, I wouldn't quite know how to do that though is there a simple way?

1000w PSU is pretty borderline for mining with 6 card rig, to be honest (Always give yourself headroom with PSU. Efficiency is better and You can have a nice night sleep knowing that You aren't pushing Your PSU too hard)
Try GEN2 on Your PCI-E lanes.

That is very true!! and yes I tried Gen 2 a still problems with the 3rd GPU Cry

I really don't know what else to try, I completed another fresh install of windows thinking it would be maybe a reg key that had got corrupt but yeah didn't work..

Debating to buy 3 more PCI risers and possibly RMA the motherboard for a new one or different one..

I've tried to reach out to Asrock but they haven't got back to me yet. Its so frustrating because this motherboard is meant to be a mining board, I wasn't expecting any of these problems...

I RMAd one of my H81 MOBOs on 20.09 (no POST) and I haven't heard anything about it from then... It seems that a lot of AsRock H81 Pro boards are faulty in some stupid way Angry

Hope everything works out for You and You can get a new MOBO fast if this problem doesn't get fixed!

Thats crazy, im glad you managed to get that sorted!! And thanks, I've literally spent nearly 12 hours today to try resolve this, have never been so stressed in such a long time haha. I think I will literally just RMA the board at this rate. Praying that will solve the issue.

I've had some problems with the exact same PCIe riser you're using

Don't know why, but I never made it work properly, I have to change to this kind of risers (Molex risers) :

Never explained why Huh

No way really, did you have the same issue as me? Or was it something slightly different, I am also debating to just purchase 3 new PCI risers to see if this would actually make any difference

I know the stress when shit like this happens! Being a student and after building a mining rig that doesn't POST with the hard earned money... Had times like You do right now, just spent days to get something to work. But in the end things worked out, they usually do! Wink
