To overclock or not?

[FastGame]

At this stage the only benchmark I can run without windows crashing or locking up is PCMark 2002. Others such as 3DMark 03 crash about half way through

You're going to need to fix that, stabilty is paramount

Can you lower the multiplier to 10.5 and then raise the FSB a little at a time ?

I also upped the cpu vcore voltage from 1.650 to 1.675 cause I was getting random crashes or windows rebooting by itself.(should I take it further?)

You can raise it more as long as the CPU temperature stays within reason. You should also raise the memory voltage.

Use Prime95 to test stability, you'll crash fast if things aren't right.

Ok, After resetting cpu heatsink and obtaining lower temps I have been able to use all benchmarks without any problems. Downloading prime95 now..
What do you suggest I do now to push the overclocking further to find the wall of my system?
Should I raise the mem voltage if system is running stable now?
