Q6600 w/ Arctic Cooling Freezer 7 Pro
G.Skill 4GB (2x2GB) DDR2 800
Vista Home Premium x64
I've run into a wall with my overclock: I'm stable at 3.04GHz (380 fsb x 8 CPUM), but anything above that and I get a BSOD. I've tried to get higher with different multipliers but it's the same story every time. I've flashed to the latest BIOS, and my current settings are as follows:
-CIA2, C1E, E1ST, Virtualization, No-Execute Memory Protect, and any other speed enhancements have all been disabled.
-1:1 RAM divider with 5-5-5-15 (default) timings.
-DDR2 Voltage: +0.2V
-CPU Volt: 1.35625V
I'm fine with temperatures, and I'd like to get to 3.4GHz. Any suggestions?
Enable loadline calibration if your board supports it. Also increase vcore further. Intel's "recommended" vcore for Q6600 is up to 1.5v. It's a tough chip, and will tolerate a lot. Keep an eye on temperature, of course.
