3080ti FE nbminer 39.2 Mining ERGO hashrate issue #439

Open liveleeiow opened 3 years ago

Hi.

I have a strange issue with my mining setup.

Info as follows:

OC Settings:

Screenshot-2021-09-13-at-20-37-18 Screenshot-2021-09-13-at-20-37-27

I rdp to my rig. When rdp is connected and i'm watching I get a good hashrate:

As soon as I disconnect from the rdp session the hash rate dramatically drops:

This issue is repeatable and does not appear to be related to uptime at all.

Help!

Thank you.

Could be the same kind of protection as on the 3060's, try letting a screen plugged in the GPU to see if the hashrate is stable after that.

If it's the case buy yourself one of these :

Thank you.

After posting I did a little more testing in front of the PC

logged in and screen on - full speed Screen saver on - lhr Turn monitor off - lhr Load up a game, and leave it active, turn monitor off. - getting 230s, so that’s significantly more than lhr but not 100% max.

I’ve ordered a hdmi dongle. Fingers crossed this resolves it.

thank you.

Noice,

So turning the monitor off will always put the LHR lock, but i'm quite surprised that the Screen saver had the same effect.

Didi you manually switched it to screen saver mode or did you let it still until it popped up ?

liveleeiow commented 3 years ago

I was in a hurry so limited time to test. I set screen saver to blank and then manually clicked it into preview.

I’ll test later with a normal screen saver that kicks in automatically.

Ok, now i'm really confused. Monitor left turned on, no screen saver eabled. Look how the hash rate falls away over time here. Is there some black magic happening somewhere to slow these down?

You are hitting LHR lock and it's pulling you back. The extra load of being RDP connected is keeping you from getting caught by the LHR, once you disconnect it get a little more hashing in, trigger LHR, and it pulls you back. bring down core voltage/freq more to keep you under the LHR caught limit. HAd the same issue with my 3060ti and the monitors going to sleep.

matrixcoding25 commented 3 years ago

I agree with madsci1016 LHR kicks in when core clock is too high on ergo my 3080ti does same thing

liveleeiow commented 3 years ago

I've found an OC that's giving me a stable 260 at 210w.

Thanks for advice.
