I hooked a 10k to the vsen on the core and A 20k on the fb pin for the mem. I don't know how to read the data sheets but remembered using fb on my 9700 pro and saw at xbits they used the sens leg on a ti 4600. Do you think I would be better off on the fb for the core? The voltage goes up with it on the vsen. The only thing is that I was only able to gain 15 mhz. As far as the ram goes I got mine from 730 to 760 with 3 volts. The thing is that 3dmark 01 is clean at 760 but if I bench 03 I see artifacts in proxy above 720 just like I do with no volt mod.
