Currently getting 180-190kH/s on my 660Ti (not OC) with this setup:
cudaminer.exe -H 1 -d 0 -i 0 -C2 -l K14x14
on 64bit cudaminer it is slightly slower and im getting 160kH/s
It's very similar for me. Interesting launch config by the way. I shall try that one.
Maybe the 64 bit compiled kernel version is running into a register limitation, as pointers are then 64bit and require 2 registers each. I can compare the resulting PTX code to verify the assumption.
I found it somewhere on the net :-)
With other configs, I have only 80-150kh/s, dont know why. People here have more kh/s than my GPU. With this config, it it running better.
Maybe there's a difference between AMD and Intel CPU?
Maybe...I have Phenom II x4 955 3.2Ghz. When mining, it is utilized about 30%.
