3080ti Core clock is unstable #396

jagshookup commented 3 years ago

I tried the LHR with my MSI 3080ti and I noticed that the Core Clock is unstable and doesn't maintain a hold on one speed. I switched back to T-rex and noticed that it holds what ever settings I set. This could be the issue some of us are having. I tried both of the last two versions of NBminer and nothing seems to work. I started getting 75MHash and then it drops to 40 MH or with v39.1 it stops at 60MH. Changing my Overclocking in afterburn doesn't seem to help much either. So for now I'm sticking with T-rex. I get a solid 65MH rate on my 3080ti. If anyone has any fix for this please comment. I have updated my Nvidia driver to the latest driver and I swapped it from gaming driver to studio and that didn't make a difference.

I have the same problem. I've heard that some of 3080ti have this kind of limit. And my RVN is 46mh at max. ergo and cfx are both ok.

did you do any twist in afterburner or just running at default to do mining?if u do twisting in afterburner can i get to know how you change those settings?

The same issue with my MSI 3080 TI Gaming X Trio. Locking the core clock via the curve editor in MSI Afterburner does work, but only when the memory clock is low. When I set the memory clock to +500, the core clock was stable (1395 MHz on 750 mV, works with T-Rex), but when I changed it to +1000, the core clock dropped to ~1000 MHz and started jumping all over the place, up to ~1300 occasionally.
