Hey all, I have a half dozen HD 6770s and a trio of HD 6950s that are all mining away for me. I am using GUIMiner (latest version) on Windows 7, both machines are dedicated miners and all GPUs are Overclocked but none are overvolted (yet). I also have the memory underclocked to 600, which is the lowest Afterburner allows by default.
So my question(s) are as follows:
Should I edit Afterburner to allow me to underclock the memory below 600? Temperatures are fine on all GPUs as is, so unless it actually raises hash rate I don't see any reason to go lower?
I discovered that 200mhz and 256 worksize gives the best hashrate on my card
