Okay, so I'm trying to clock my Q6600 to 3.6 with stability. I have managed to get to 3.4GHz with no trouble. However, at 390FSB, the system is stable with day-to-day usage, but Handbrake BSODs it with an 0x00000124 error, Prime95 fails within a few seconds on either cores 1 or 2 (0 and 4 haven't failed yet). After reading This Bit-Tech Article, Bindi says the GTL reference voltage should be 0.67xthe CPU Vcore. With my Vcore at 1.38V, 0.67 of that is .924 Volts. Now, On this board, the only relevant voltage that is that low is the CPU Reference voltage, currently set to .840V (default is 0.760V). My query is, the voltage range only goes up to 1.010V, so is .920V going to damage the chip or board? I've also had to bump the MCH voltage up to 1.240V, and set the reference to .840, same as the CPU (default is also 0.760V) Anyone? More info available on request.
