If you guys insist I can try some quad cores primes, BUT (and that's a big but) I do not understand why some of you guys are so blinded with Prime.

Is there any real life application / game / benchmark that put some much stress on the components as prime?? I don't think so

I do overclocking for near a decade and I always follow the 10 - 15% rule for 24/7 use and I never had stability problems.

For instance if I had a CPU that run most of the benchs (superpi / 3mark, etc) at 4.000Mhz, for daily usage I always run it wih less 10 to 15% of the max OC, more or less 3.500Mhz in this case.

Please do not flame this, it is just my opinion. I respect others opinions, if you consider a system stable only if passes a 100% stress prime it's ok - use it and stress it..

The most important thing in OC it is not to have stress (prime or other) but have fun a enjoy your system
