|You've overclocked to 3.89Ghz & had to overvolt the hell out of the CPU to get it to run stably. Intel CPUs won't die from heatstroke, but they will die from electromigration caused by over-overvolting. In the old P4 Northwood it was called "Sudden Northwood Death Syndrome". The max safe voltage for the E5200 (according to Intel) is 1.45v...your's at 1.664v. It will not live a long life at that voltage.|
And it doesn't look like you took my advice about how to overclock. Let's say you can reach 4.0GHz...which of the following would perform best & why?
1. 12.5 x 320MHz
2. 12.0 x 333MHz
3. 11.5 x 348MHz
4. 11.0 x 364MHz
5. 10.5 x 381MHz
6. 10.0 x 400MHz
Regardless, your overclocking limitation has to do with the motherboard or more specifically, the chipset the board is based on. Both the G31 northbridge & ICH7 southbridge are outdated. The southbridge is especially old (2005)...3 generations behind. The P45 / ICH10 combo is where it's at for Core 2 systems.
It would be pointless to get a quad until you get a decent motherboard. And if you were to get a decent motherboard, you would be able to make the most out of your current CPU...something like 9.5 x 410MHz instead of 12.5 x 311MHz? That's a 30%+ increase in the FSB speed. Remember, performance isn't all about the CPU.
BTW, why are you asking CPU questions in the gaming forum anyway?
