However, I'm disappointed by the autotune. It promises me 288kh/s or even 307kh/s and then the real world speed is mostly in the 245-265 range, 80% of the time in the 245s.
On the plus side, I experimented for an hour and I found the perfect (I think) config for my 480. So I'll share.
cudaminer.exe -l F15x16 -C 1 -i 0 -m 1 -H 1 -o stratum+herp -O derp
This (with a clock of 840 core / 2100 mem, at 1.1V core) gives me a whopping 275-276 kh/s on a GTX 480. Very nice! It's 30 more than I was getting with the old build a week ago
. It's weird because -C 2 on that F15x16 config gives about 270 kh/s but -C 0 gives 260ish. It's strange because -K15x16 -C 0 is the fastest (~270) and -C 2 is the slowest, but not with the fermi core.Anyway, Christian, I was wondering if you can make the "autotune" more "accurate" somehow? Make an option to run much longer but run benchmarks with "real world" performance, and go through -C 0 -C 1 -C 2 automatically? I don't mind waiting even an hour if at the end I'll know it's the fastest "real world" speed that I can get from the card. Even though, like I say, 275 isn't a bad number :-) .
