I know of a few people running a Q9450 at 3.6Ghz with stock volts all around. The issue is the board you get to run it on; in my case I got the P5E3 Premium, and it is a b!tch of a board for my CPU/RAM combo. I can run everything stock at 400x8, except for the RAM, it needs +.04v to be able to run at 1:1 with the CPU. If you want to run a CPU at 3.6Ghz 24/7 then this is the chip for you since you don't really any voltage at all; you just need to read up on the possible board you want to use, and look for the RAM that is performing the best with it. In the case of the P5E3 Premium, seems that the CellShock PC3-14400 is the most stable RAM.
