I've been lurking this thread ever since I started mining a week ago. Thanks for all the hard work everyone has done.
I've got 2 EVGA 670 FTW OC'ed hitting 453 kh/s. Supporting hardware is an i7 3770k @4.6ghz, EVGA Z77 FTW motherboard, and 8gb of ram.
I've tried as many combinations of arguments as possible, and these 2 are getting me the same results:
-H 1 -i 0 -C 1 -m 1 -l K14x16
-H 1 -i 0 -C 1 -m 1 -l K112x2 <- way more consistent
About 220-230 kh/s on each card.
I've also noticed that if I put in an argument that cudaminer doesn't like, I have to reboot my computer since it drops my GPU clock speed to 750mhz and seems to lock it there.
I'm hoping for some more K20 optimizations in the future!
Overclock and hash rate screenshotI just discovered the K112x2 config last night, I get about 218K/hash max per second with a slightly faster core clock than you, so nicely done. I ALSO have the problem of getting my gpu frequency locked to 750mhz.
