Hey guys I didnt actually know what to put in the heading so sorry if its confusing.

So i have 25 cards running, mix of all 470/80 & 570/80 etc as cards have been hard to get for a while here in AUS.

4 main rigs all running

ASRock Z270 Pro4 motherboards
All the same risers
Corsair RM 1000i psu (5 card rigs - space wise at home this is a preference for me)
SSD
8gb Ram
Win 10 home
17.8.2
Claymores v9.8

Every card has been tested as has the risers

All rigs are essentially the same.

Rig 2 - http://prntscr.com/gcwjra
Rig 3 - http://prntscr.com/gcwkmd (Errors)

The same error is happening on Rig 4

This WAS happening on my Rig 1 as well but it just sorted its self

If i run 1,2,3 or 4 cards they are all fine, plug in the 5th and 3 kick out.

Does anyone know of a fix, it happened when i was setting up a couple of weeks ago as well but again they just sorted themselves out i don't know how.

Cheers
