Started tweaking the 6600go with coolbits, measuring any improvements with Cinebench.
1st run not overclocked, actually factory underclocked at 100MHZ clock, 330 memmory.
2nd run clocked to 441Mhz / 735Mhz
GFX/C4D OGL/SL OGL/HL SL/ratio HL/ratio
1- 276 1090 1061 3.95 3.84
2- 279 1165 2913 4.18 10.44
Not too bad a speed bump, it already runs AH very well, I'll log in a bit to see what kinda performance, if any, I get.
