hello guys,

yesterday I went with the latest nVidia drivers, updated to 5.5c and changed the 6pin to SATA cables on my riser boards directly to power them by the 6pin cables from the PSU.
Before, when I was running with the SATA adapters and not the latest drivers, 5.4c miner I had a stable rig, runnin each RTX 3080 at 94.5mhs with 70PW and +700Mhs.

Now , one of the cards is hashing lower than expected - with -0.5mh, when the GPU is not connected via HDMI cable and with -1.5mhs when its streaming.
If I start playing and tweaking , a 2nd card starts losing MHs and starts crashing...

I looked that the miner and it seems that some of the cards are getting 8-10 degrees hotter than the others, and one card is running always @ 100% fan speed... If i try to lower the fan speed in MSI, the card throttles within minutes.

And all this was stable AF 2 days ago, while i was running the cards with the SATA Connectors...
May the problem be caused by the drivers or does it look like a hardware problem?

Thanks for your help!
