3080ti LHR detection when enter in PC through Team Viewer #774

Open M3dic opened 2 years ago

Using more than 1 3080ti GPU.

Every time I enter PC with Team Viewer I see LHR detected.
When minimized window everything is working good. When I open Trex window second GPU going low Hashrate.

What are your current settings for that 3080ti? I've been mining with a 3080ti as well without issue. It took some tweaking to get it stable but I seemed to have gotten it pretty rock solid now.

--mclock 1000 --cclock 0 --pl 82 --lhr-tune 73 For 2 cards. I have problem only with second. Haven't tried it with 3 GPUs yet.

Try lowering the power limit to 75%. You want the core clock to hover around 1400-1500Mhz. I'm also leaving the lhr-tune to default (aka don't set this). I have a Gigabyte 3080ti and EVGA 3080ti and since they both have wildly different power limits/clocks, it takes time to find the right settings for each. My EVGA power limit is set to 65%, whilst the Gigabyte is around 75%, but they're both running around 1500Mhz (270-ish watts is also where you want to be). The Gigabyte 3080ti is yielding around 80-85MH/s and the EVGA gets around 78-80MH/s (it's also my primary GPU on this machine so it'll be lower typically).

Putting extra load on a GPU is causing hashrate drops which in turn is treated by the miner as an LHR lock. If you do that too often (more than one every 20 minutes), the miner will decrease LHR tune value. To prevent that from happening you can use --lhr-autotune-mode off parameter which will force the miner to keep using the LHR tune you specified in your bat file. Occasional "LHR detected" event is not a huge deal: GPU is idle for ~20 seconds, and then mining resumes.
