well guys i finally got mine to do something besides run a little oc, it took some seriouse vtt and vmch voltage boost to do anything over 430 fsb, unfortunatly i am still having problems with getting the ram stable at anything towards 500mhz even my cellshock that should do 4-4-4-12 500mhz stock (ddr2 1000)

anyways i got my 6600 uo to 500x8 running ram 1:1, tried everything i could to get the ram stable but a no go and it would fail memtest everytime, took the oc back to 445x9 with ram 4-4-3-4 and it is perfectly happy

i also took off the NB cooler and removed the thermal pads from the NB and the PWM area and put as5 on it and trimmed the mounts on the PWM area so it would all sit nice and flush, temps for the pwm get to about the high 40's when under load, pretty good i guess

heres a few screenies
