Having any issue. Using Claymore dual miner v9.5

Yesterday I inadvertently restarted a machine that had been symptom free for more than 100 hours. After restart 4 of my GPUs were reading between 27-28 Mh/s and the 5th was just over 4 Mh/s. I disabled that miner, isolated it and ran it by itself. The card hashes ~27 Mh/s by itself. Plugged them in one by one and until I get to the 5th card everything runs normal.

I moved to another machine, different motherboard different cards and the same thing is happening to this machine now as well.

Can anyone offer an explanation?

I have a biostar TB250 BTC MB and 6 Aorus RX580 GPUs.  I am running 17.5.2 drivers on Windows 10 pro.  Windows will recognize all 6 cards.  Claymore 9.4 will start with 4 cards, but when there are 5 or 6 it will not get past the initializing OpenCL.

Any idea what is causing this?  I have a work trip this week and would like to get this fixed before I leave for it.

I will pay a consulting fee if someone can help me.  PM me for details.

Thanks

What series GPUs are ya'll using??? RX 5XX or 4XX?

Aorus RX580 8GB Samsung - has anyone had any luck getting the hash rate above 27 MH/S?  If so, can you share your settings/BIOS mod?

Thanks.

I have 6 Sapphire Nitro+ RX 580 with 4GB Samsung Memory.  I can't get above 24 MH/s.  I can't see to find any good BIOS mods for this specific card.  Does anyone have anything that works well.  - Thanks
