Memory clock definitely helps with Kawpow. Good low/stable Graphics clock and upped Memory offset

Try to tune the card like this:

1. Set clock offset to 0 and mem clock offset to 0
2. Set power to about 60%
3. Set fan manually, for now, at around 80%
4. Start miner
5. Slowly lower power until you find the point where the clock drops off..like way off. my card that is around 1100-1245. at that point it's dropping to 400Mhz
6. Go up 2 or so on the power and get the lowest stable clock ( AS an example one of my RTX3070s will do 1425. At 1275Mhz it's good 99% of the time and then throw an error randomly. I run at 1290Mhz on ETH and Kawpow )
7. Once you figure that out, start going up with the memory offset to wherever you are comfortable. I crank it 😉 That's where you gains are and you need to decide how much wattage you are ok with, temp control, etc. I run all my GPU fans a minimum or 80%

write down your findings for each step like the example I show below.

locking the clock as show below is a big help

my 3070 tests

Clock MemClk Hashrate 1290 6800 25.80 MH/s 1290 7300 27.66 MH/s 1290 7400 28.15 MH/s 1290 7500 28.51 MH/s 1290 1290 8000 30.47 MH/s 1290 8200 31.27 MH/s 

While testing, wait on each to settle. The mining software usually uses averaging for MH/s display. wait on each step until it settle at a value.

Other Stuff

Nvidia Inspector is a good overclocking and testing tool. It also allows you to change settings via the command line and from batch scripts. Check it out

I would close and exit afterburner and use that to test with. I use nothing else except AI Suite to set a fan curve.

You can lock the clock on Nvidia cards using the 'nvidia-smi' utility included with the drivers. Open a cmd prompt as Admin and see if it's in your path

c: nvidia-smi

that should show something like

C:WINDOWSsystem32>nvidia-smi Sun Apr 25 18:22:50 2021 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 461.72 Driver Version: 461.72 CUDA Version: 11.2 | |-------------------------------+----------------------+----------------------+ | GPU Name TCC/WDDM | Bus-Id Disp.A | Volatile Uncorr. ECC | | Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. | | | | MIG M. | |===============================+======================+======================| | 0 GeForce RTX 3070 WDDM | 00000000:0A:00.0 On | N/A | | 80% 41C P2 123W / 154W | 5798MiB / 8192MiB | 100% Default | | | | N/A | +-------------------------------+----------------------+----------------------+ 

You can lock the clock with the following command. That will automatically keep the power at just the right spot without having to set it manually. It's totally locked at whatever you set it at.

c: nvidia-smi -i 0 -lgc 1290

And an example batch file using Nvidia Inspector with it would be:

rem RVN-Settings.bat

"C:MiningNvidia InspectornvidiaInspector.exe" -setBaseClockOffset:0,0,0 -setMemoryClockOffset:0,0,1500 -setPowerTarget:0,58 -setTempTarget:0,0,50

c: nvidia-smi -i 0 -lgc 1290
