When my rig run with 1x3060ti, 1x3080, 1x3090, the power consumption and hashrate are very stable.
When I try to add another 3090 into the rig, then either one 3090 (random) will become unstable, the power consumption and hasdrate will keep dropping
Working fine at the beginning, both cards are running with 325w + 126mh
Then keep dropping until below 300W…
I have tried below:
- replaced the power cables
- changed to different pcie slot
- added one more psu to make sure the power is enough (tried 1200w and 1750w)
- removed the 3060ti and 3080, but the issue still happen for those 2x3090
- no matter how i raise the PL, mem clock or core clock, but it won’t change anything on the hashrate or power…
- if i lower the PL, mem clock, it does lower the hashrate and power
- this issue only happen on the 3090, but not others
- tried to use phoenixmine, lolminer, t-rex, but no luck
- tried to mine different type of coins, BNB, ETH, TR, no luck
- both cards are new (inno3d 3090 x4)
hope someone can help, million thanks.
