Anyone experience hashrate drop on P106-100 in SMOS?
I had this before but not happen for last year, and recently started on few rigs, mostly with 8 card configuration.

The situation is that rig reboot itself (because of some conflict?) and hashrate drops to 21Mhs per card samsung mem, or 18Mhs per card with Hynix mem. All cards in rig are affected. When I change poweer limit only 1W they back to work normaly next few hours. I've Tried different miners, OC settings...

What image do you have ?
We have two images with two different nvidia drivers.
The newer one (is ment only for 1660 cards because it supports them), but for rest cards it makes hashing speed drop so we do not recommend the newest for any other cards.
Can you confirm what kernel version and nvidia driver you have ?
If you do not have this version, i suggest to reflash this rig using this image:
5.0.21-sm9 / nv430.40c10.1 / v1264
Select rig -> Actions -> Advanced commands -> Reflash -> set SM-5.0.21-9-a18.20-n430.40-v1261.img.xz - > Confirm
Let me know if that helps or not ?
If not, please write to me at admin@simplemining.net
Maybe your riser is broken and makes whole rig unstable ?

P.S - does the gpu mining nromally and then drop happens wihtin what time ?
Reload or reboot helps restoring speed ?
Can you try with phoenixminer to test if maybe claymore miner could cause this ?
