Overclocking i5 2500 (NOT 2500K) PAST LIMITS

Okay, so what's the highest I could get with a 2500? I just bought one because it was extremely cheap (<$120) and I couldn't get a good deal on the 2500k. I have a Coolermaster Hyper 212+ heatsink to go with it as well, but I've never touched the base clock.

Anyone have any tips?

Base clock might be able to be turned up +1 - +3 then up the multiplier if you can. Likely won't see more than 200mhz faster than stock. I tried this and ran into stability issues with an I5 2400 at anything faster than stock.

Non K series means your basically stuck with what you bought.

You can OC through the Turbo multiplier by 400Mhz because of the "Limited Unlocked" ability. So that's 4.1Ghz on 1 core, 4.0Ghz on 2, 3.9Ghz on 3 and 3.8Ghz on 4.



You CAN also use the BCLK to OC slightly, but I don't recommend it. 103-105Mhz is about as far as you can safely go with that, and that's not really even worth it.

If you are very lucky to have the system stable you might get over 105mhz on the base clock but anything higher is where no one dare ties to go. Some have gotten up to 110mhz but that is really pushing it. That is why I am still in the stone ages with an ancient 1156 system and a 775 as well a am3+ 990fx. As for cooling you have that covered.

So, how much FPS gain generally would I see between a OC'd 3.8 ghz i5 2500 and a OC'd 4.8 ghz i5 2500K?

Not a lot, unless it's a VERY CPU dependent game. Having a good GPU matters a LOT more.

Isn't worth the effort. 3.8ghz for what most people need is more than enough.

How about ArmA II? I've been having a hell of a time getting it to run on my computer (6950 2 GB unlocked and 955 Quad Core)

It should be just fine at stock speeds on a 2500, actually (a SB i5 is a hell of a CPU, remember, and quite a bit faster than a 955), but you may get a few more FPS at 3.8.
