I use cgminer...... using cgminer you set all the overclocks within cgminer.... no external programs are used...
intensity" : "9,9,9,9",
"vectors" : "2,2,2,2",
"worksize" : "128,128,128,128",
"kernel" : "diablo,diablo,diablo,diablo",
"gpu-engine" : "915,920,920,920",
Why worksize 256? I have never seen a larger than 128 worksize do anything positive unless it was on a 7900 series card....
I ran my Spapphire extreme 5830 with CGMiner at "--gpu-engine 960 --gpu-memclock 300 -k phatk -w 256 -I 8" and I got 310MH/s. This was on Win7x64, always using the newest drivers but keeping SDK 2.5.
In fact, for all my 5xxx cards: SDK 2.5, 300mem, and worksize of 256 seemed to be a very successful combination.
Cool.. I will give it a try... When I first started I played around with all sorts of settings on my two original 5850's and 128 always seemed to work best....
I believe it's a difference in the kernel's... I have been using the diablo kernel lately instead of phatk..... had stability issues on one rig got annoyed and gave up on using the older sdk...
