I have water-cooled rig with 4x RTX 3090 and 2x RTX 3080. Both 3080 are the same Gigabyte Gaming series. One of them works perfectly, 98MH/s, no problem. The second one still freezes on 0MH/s after some time. If I overclock it to the same values like the first one, it goes 97,…MH/s but after approx 10 minutes goes to 0MH/s a and Hive is restarting. If I overclock it less (1800MHz memory and 200W power limit) it can mime for about 1-3hrs but then 0MH/s again.
I tested it in Windows to see memory temperatures and this is ok (about 90°C).
I changed pads for 2 times for sure but no effect. Any ideas where can be the problem?
So… One cable with 8 pin to each card (2 cards) and for risers connect molex (cable with four pins) two different cables if you have… The CPU cable they need special cable to use it for GPU…
From tommorow and still stable. I overclocked less to -300 gpu, 1650 mem, 230W pow. limit and works fine. Hash is 95,5MH/s. I had no idea that card could has problem with less then 1800
