3080 LHR Only 64mh/s

[CryptoLLC]

Hello Gminer. Im using the most updated Gminer version on windows 10 with the most updated Nvidia Drivers. I have 3080 LHR from Gigabyte. These cards are only getting 64mh/s. Can someone please let me know what settings for gminer I should be using? Here are my current settings. By the way I have been trying different configurations but can not get pasted 64-70mh/s.

[common] algo=ethash templimit=90 color=1 watchdog=0 p2state=0 intensity=100 pec=0 api=1000 tfan=100 tfan_min=95 tfan_max=95 cclock=0 mclock=800 lock_cclock=1500 lhr_autotune=0 lhr_tune2=10

last release note for 2.69 says "added auto-tune for LHR GPUs", so you do not have to use lhr_autotune=0 and lhr_tune2=10 options. try without them.

I did try that as well. Hashrate never goes above 65mh/s

[thonik123]

well, I have 37 on 3060 ti, so probably 64 is really not bad for 3080?

ummm....

i think that is relate with templimit_mem...

GDDR6X is the hottest memory in graphy card with mining.

If memory temperature is too high, card work will be down frequency.

But i'm not sure if it is the best answer, i have 3080 LHR too, and it's work with 64~65 MH/s.

I think LHR card is not suit in minig because expensive, low value for money, high power....

I also have 3090 and the temps are 100 on those 3090. Vram never goes above 102 and still the speed is 64. Its not the temp. I was reading online that some other miners were getting 85mh/s but for gminer Im only getting 64. If anyone can get 3080 LHR to run at 85mhs please let us know. Thank you.

Are you sure 3080 LHR can getting 85 MHS? Not 3080 ti LHR?

[CryptoLLC]

Maybe it is the ti version. But even if that; the 3080 should get at least 80mhs vs the ti at 85mhs. Either way Im hoping the speed can be increased from the current 65.

[sars30323]

RTX 3080 LHR now is difficult to getting 80 mhs, but i think the limit can getting 70 mhs.

i adjust memory frequency to +1500, core clock -800, and it getting 66~68 mhs.

otherwise, you can refer to this URL's hashrate information.

good luck~

I tried to compare hashrate between t-rex miner and gminer. under same setting, core clock 1200, mem +1000, vcore 0.718mv, pl 75% t-rex : 70 - 71, higher memory temp: 100 - 104 , Power consumption: ~230 w g-miner: 65 - 66, lower mem temp, 92 - 102, power: 150 - 230, avg : 185w

you can also observe GPU/mem controller loading from GPU-Z chart t-rex miner is always keeping 100%, gminer jumps from 50% to 100%.

t-rex gives higher hashrate, and gminer provides better efficiency.

I do have the same issue with a 3070 ti. On trex i can get 60/61mh but on Gminer i can only get 55/56. It does start at 60/61 and it drops. It might be hitting the lhr lock.

go get 2.70 & 471.11
