I have never done oveclocking in my life. Easy Tune utility crashes my system all the time. Is there anybody to tell me the optimum bios settings (with all stock hardware) for the following system. I have heard that 4 GHz is possible but I dont need to get too high. I want a stable system with stock cooling...Here's the configuration:

OS: Windows Xp Professional
File system: NTFS
Motherboard: Gigabyte GA-965P-DQ6 (Bios Version F7)
SATA: RAID10 (with 2 Westen Digital 320 GB + 2 Seagate 320 GB) (2 mirrored SATA's are stripped)
RAM: Twinmos DDR2 667Mhz 2x 1GB
Video Card: Asus EN 7950 GT

The good news is that the E6600 is easily overclockable by just increasing the motherboard FSB. That cpu has a normal FSB of 266, and you should be able to bump it up to 400 (50% overclock), but do it in small jumps of 33 at first - 266->300->333->366->400. At each jump, run a benchmark program to be sure that everything is working as expected: 3DMark05 (or PCMark if video benchmarking is not critical). 50% is extremely good for any cpu, and you may be able to go higher, but as a beginner I would not recommend it. As Gary said, you need better cooling when you go higher. You also need to check if the SATA controller is affected by this. I have an MSI K8N Neo2 Platinum that I could only use certain SATA ports on because the other ones were not locked to the same frequency when the FSB was changed.
