Have you tried increasing the freq over 250 since changing? - Looks like extra CPU might equal more work into the asics. I am not sure how or where the file is not with the new bios, that you can set from interface. Anyone know where to edit that file?
TIA
I have one S3 running at 262.5 for the last 5hrs+ and like I mentioned before in this thread, it looks like my pool-side hash rate is higher than usual, so I would nod to the assumption that less load MAY equate to more work into the asics (and more efficient submission thus less rejects!).
I'll have to come up with a more meaningful assumption after I've run for over 24+ hrs.
