I have a i5-3570k and a Hyper 212 EVO cooler. I have it overclocked to just above 4 GHZ right now. what's a good speed to OC it to? this is my first time OC a processor. i also can't afford another one so please bear that in mind (I don't want to push it to it's absolute limits)

More about : good speed 3570k

4 GHz is more than enough. Id only push it farther a few years from now when it starts to get slow.

I think it actually depends on your sample & what your max load temp is. I think 4ghz is minimum for that awesome chip. I would shoot for 4.2~4.4ghz using EVO, and see what your max load temp is using hw monitor with prime95 blend for at least 20 min. Several things effect temp (case cooling, ambient temp, heatsink and thermal paste, cpu sample & luck, vcore voltage added, etc), so everyone will have different results. Also, I know everyone has different temp standards, some say stay below 70C, and some say below 80C, but my personal max load temp is 75C or lower or any core, not average.

I had mine overclocked to 4.4GHz but very occasionally (once a week) my system would freeze and I needed to do a hard reboot. I then dropped down to 4.2GHz and has been rock solid

I could probably have stabilized at 4.4GHz but would have had to tweak the voltages a bit more, plus my CPU is running a little cooler now.

After playing Battlefield 3 on high settings at 4 ghz for 30 minutes or so the max temp i got to was 65 celsius. somewhere in the low 70s is the absolute max i want it to go to.

Best solution

I would just stay where you are. Honestly, why bother pushing it if you're happy where it is? Things can only get worse.

I have been @ 4.3ghz with everything set to auto for a few months now, no issues. I ran it @ 4.0 the day I bought it. I only did 4.3 just to see if it could. 4.0 was plenty.

If you are OC simply for the "performance" 4ghz vs 4.3ghz is "only" 7.5% difference. That is the difference you really won't feel much. But if you look at it slightly different perspective, difference from stock, 3.4 vs 4 is 17.5% difference, and 3.4 vs 4.3 is 26.5% difference. If I were to choose 26.5% vs 17.5%, I would definitely choose 26.5%. I recommended to OC to 4.2 ~ 4.4ghz, because that is what majority of people, and most of my buddies, are setting to. I am not saying that is the "best" decision, but simply that would be "my" decision.

Overclocking at moderate~aggressive levels require lots of research, time and effort, so I think that is something everyone needs to understand before they try it.

i'll probably push it up to 4.3 in a a year or so once things start to slow down. thanks for the advice
