I noticed the issue again with the miner seeming to drop hashing speeds on cards by around 100 H/s per Vega 64 card. I looked back through the mining log and didn't see anything strange. I tried resetting the cards while the miner ran (Overdriventool -r and then -p) and that didn't fix the issue. I closed the miner down and restarted it. That caused all of the cards to go back up to where they were at originally.

I just lowered it to 1095 from 1100 on the memory.
well, that's exactly what happens on my vega 56 rig and why I'm trying SRB (besides the fact I'm not overall happy with cast). Goes up just fine, let's say 3 vega do 6K. after a while, one drops, and it may be like that for hours, or really drop to ridiculously low hashrate, and/or more cards to the same.
lowering P7 or P3 does nothing to it... which drivers are you using?
