I have successfully overclocked my Q6600 from 2.5Ghz to 3.6Ghz, all unstable in a RTS game called Supreme Commander. Why? I ran Orthos stably for 24 hours on each setting and it doesn't fail (Temps are below 60C). I followed the Q6600 overclock guide exactly as the OP said to do and it isn't stable in Supreme Commander. I have speed step and all other power saving option turned off, ram at very lax timings (5-5-5-15) and tried all voltage level (1.2500-1.3500). This damn game is only stable at 2.4Ghz (266X9), while all the other settings would crash within 10 to 40 mins.
Here's my spec:
OCZ 700W GamerXtreme
Windows XP SP2
It is just Supreme commander, no other games. I have the latest patches on, and yet at any settings other than stock will make the game crash. I can run Oblivion, Call of Duty 2, Half-Life 2, CS, Call of Duty 4 Demo, and various other games without crashing.
Thanks for the link, will be looking to see if it is just Supreme Commander being too demanding or problematic.
quick question guys. I have a issue with my q6600. I oc it up to 3.6ghz and been working flawlessly, but when i updated my bios for my motherboard because the memory timing issue causing not to post or is picky like it wont post if the frequency is 950 but boots up fine at 960 lol. But other than that it just works flawlessly. But right after the update i applied the same exact settings and now my overclocked is unstable random reboots. But at least it got rid of the memory not posting at a specific mhz issue.
I really don't want to push the voltage to 1.4 it was perfectly fine at 1.3675 before the bios update. this does not make any sense. and i really don't want to roll back the bios. The only thing i can think of if the new bios revision screwed up the voltage readings not matching up to what it is really being applied to the cpu.?? Sure sounds like it
