Hello Tomshardware members, I have another quick question.

How far can I overclock my E5200 without changing the core voltage?

I usually get 20-25% without raising the voltage. For example, if the cpu fsb is normally 200, try 240. For stability, I drop the ram speed first unless you've figured your ram can handle the extra speed. If you're using 1333 or 1600 ram, then you won't need to adjust the ram speed before you raise the cpu fsb as socket 775 boards normally run the ram at 800 or 1066.

Thanks! I set the fsb to 240 (with steps ofcourse, not directly to 240, tested other fsb's first) and I get 3.0ghz without any problem. But also fsb of 250 seems to work, is it too unstable or should it work? I've checked it but changed it back to 240 because I'm scared to brick the CPU.

I had better luck with 240, but mine is amd. Not much difference in speed or performance; try 240 for awhile and see how stable it is. Some folks use prime 95, but I don't like stressing my cpu or raising the temp, so I pass on it. Use cpuz and check your ram speed; for 1333, it will show as 666 or 667 (half the actual speed).

Core voltage generally is not the problem with a Wolfdale CPU. Core temps are.

I have 3 Wolfdales (an E5200, E6600, and E7500) in office type systems. With decent cooling, they all reach core speed limits before they reach load temp limits (70 C) or max recommended voltage limits (1.45 volts).

Quaddro, my E5200 wouldn't go past 3.78 GHz at 1.35 volts (24 hour Prime95 stable). Increasing core voltage to 1.60 volts :o  didn't help. Still, that is a 50% OC from a cheap CPU.
