“Just core clock” is an offset value and can fluctuate. Absolute core clock is exactly what it says it is. This is also better for the card’s longevity as it lessens power draw + temperature throttling considerably (all things being equal).
Absolue core clock. killed my hash rate on my 3090 and 3080 and now they are not going back to previous.
I recently changed the settings to absolute core clock. The power has dropped substancially which I see is the cause of the hash rate drop. So I tried to revert them back to normal settings ie core clock and only at the very start of mining do they start off well, but pretty soon they revert back to power saving and I end up losing hash rate. My 3080 is sitting at 78 hash and my 3090 is sitting at 90 hash. my 3080 used to be at 90+ hash rate and my 3090 was at 118 hash.
initially I set them to 1150 absolue core clock to test them out, and when I saw they went to shite. I tried to revert them by going back to -100 core clock, but unfortunately the power has not increased.
I have tried to remove them from mining, and adding them back. No success. what else should I be considering?
I did take my absolute core clock all the way up to 1500 on my 3090 from the initial 1150, I tried to zero PL, but none of this has worked
For the 3080 use 1070 core and 2150 mem.
I get 99 MH at about 205 to 215 depending on gpu silcone lottery, and NB miner

Adding a Gigabyte 2070 (non super) with Samsung memory:
Results in: 44.25 MHs and 111 watts on NBminer 39.6
This card was ok (43 MHs and about 110 watts) but things started to get really interesting after locking the core clock. Haven’t confirmed the wattage number yet but if this holds, then the 2070 Super with Samsung memory might well be on the top shelf of really efficient cards.
The card above is the Asus TUF Gaming RTX 3080 (non-LHR). If anyone has better settings for this, please feel free to share it.
