I have maxed out my 9800pro AIW O/C.....i get 411/370 at stock voltages and stuff.....is my last resort to get higher O/C's to V-Mod it?....i wanna do a pencil mod if it is...(not a good solderer) is this my last resort...and cooling should be fine....the heatsink doesn't evven get hot with stock fan at this o/c...i think it has just reached its limit
