replace all of your risers

do you have any missing device drivers in device manager?

ya man, test each card till error appears, replace riser on the faulty one may fix it (hopefully) most risers have a terrible fail rate, sometime right OOB, sometimes after a few weeks.months mining Sad

i run also a free iobit softwear called "driver booster". free and works. it usually finds drivers for "PCI-E" stuff, and have had it help having all those updated
keep in mind you DONT need all the audio drivers for each card installed, as they will just eat up resources Tongue

Here's the thing. I plugged GPU 1 and 2 in and it crashes. Then I try GPU 1 by itself and it works. GPU 2 by itself and it works. So it cant be the risers can it?

haha damn thing, rigs are so finicky sometimes :/ maybe theres a PCI-E port acting up on the MB ? switch around the slots you plug the cards risers into, see what happens Tongue

make sure no dust in the slots also
just keep trying to isolate it,, maybe you can get it to 5 cards, and go from there
and update your system drivers! it could be windows just confused by all the cards Tongue

OK Update. I think we need to back up. Turns out... even a single card doesn't work. It mines happily for about 5 minutes and then crashes. As opposed to the normal crashing immediately.

So we think the risers are the culprit?

that would be my guess right now. what risers are you using?

i had an issue with risers when i built my first rig. it wasnt actually the risers, but the USB cables were bad and caused all kinds of issues. fans acting erratically, blue screens, driver crashes, everything.

test one card at a time, one riser at a time. see if you have any good risers/cables. replace any you confirm are bad. maybe even manipulate and bend the usb cable around with the system running to see if it has a repeatable impact on the system behavior
