This PSU is 850 watts? You can pull at best 750 watts from it. 150 for the rig and 600 for the GPUs. How much watts do the GPUs pull?

[burizone]

130w each GPU
i will get 1 more gpu thats why i have the 850w

Check riser then on gpu 0.

[burizone]

its look all good on the riser, this erro is random, sometimes the rig run for 10 hours without any erro and sometimes the erro comes out like every 1 hour

Post your OC settings. They might be slightly off

I have this error similar to yours. Sometimes it works for days, sometimes a few minutes… I can’t find a solution. I noticed that when I remove the 3070 or 3060ti from the system, the error practically doesn’t happen. So I thought the problem could be my old Asus motherboard (P5QC), but then I see you with the most modern equipment also having this crash… I don’t know anymore… I got tired of wasting hours of mining… Sometimes the miner keeps restarting over and over again
