I got lucky grabbing a 3070 at MSRP, built myself a gaming rig and figured I could mine whenever I'm not playing. I've done an extended run Saturday through to today - stats in the image.

​

I have some questions:

- is the ~0.6% rejection rate acceptable?

- Do the purple rejected (other) mean much? I've seen some suggestion this could mean memory instability? maybe the medium preset I'm using has overclocked too high? (not sure where I can check the actual frequencies however)

- I'm using quickminer and as noted above, set the optimisation preset to Medium. MH/s in the excavator logs fluctuate around 58-61. About 115-117w power, 510-520 efficiency. Could I squeeze out more hashrate or efficiency using AfterBurner with an underclock etc?

- Fans are at 35% under the medium present, GPU temp is 58c, VRAM is listed at 55c. However I read that 3070 does not have a VRAM temperature sensor, so is this an estimated VRAM temp? It looks very low compared to other cards which have a VRAM temperature sensor

- If I want to turn up the fans whilst continuing with the medium preset to improve VRAM temps, how do I do this?
