My hash rate just dropped by half

[JaaaaAAaaaaY]

For every 12-13 hours, my gpu hash rate would drop from around 40 to just 20 M hash and its core clock would be increased by around 500 Mhz for some reason and still drawing the same amount of power as before, it went back to normal after reopening the mining program, but it is just so annoying having to reopen the program every half day, can anyone tell me what to do?

 

My setup:

GPU: gaming z trio 3060ti LHR (normally I set it to 60% power limit and the core clock is around 13-1400 Mhz, as for memory clock, its 7800Mhz)

Mining program: NBMiner v39.1 with nicehash miner

I mean, it's a LHR card, that's expected?

No, because the v39.1 NBMiner can unlock the hash rate to 70% for all LHR cards, so the 40 M hash is already the 70% unlocked hash rate

I'm having the same problem with my Rtx 3060 ti.

Random hashrate drops can be signs of an unstable overclock or unstable other tuning-related settings.

Took me a couple of hours to find something stable. I wasn't able to get the hash rate what other people were reporting.

 

My settings for core -502, power limit -72% and 7350MHz memory (+550) for 38 hash rate on a MSI 3 fan variant with Hynix memory. It took a couple of hours to tune, because I had to keep watching NBMiner auto tune it to something stable before I stopped mining it to tweak the settings in Afterburner. You can also see what -lhr value is adjusting it to and put that in the start parameters to reduce some of the time before restarting the mining process again. The power can fluctuate between 111 and 147W even ifs its always getting 38 hash rate.

If you let it autotune you are working against it by messing with stuff yourself as well. Either under/overclock it yourself or let autotune find settings it thinks is best (which is the point of letting it autotune).

I think I got mine tuned efficiently in power and perfomance as I can in NBMiner. When I start up the miner the first 2 hash rate readings can looking kind low, after that it seems to be 37-38. Only thing with NBMiner is that it seems to restart the mining Window when I am using more than 1 video card.
