I need help OCing my 3570k, never OC'd before.


relevant specs:

750w PSU
i5 3570k
H100 cooler
4 sticks of ram, 4gb each at 1866MHz
Mobo: Asus Sabertooth z77.

More about : overclocking 3570k

Just to clarify

Im completely clueless. So tell me every setting in the BIOS I need to disable and enable, why I need to turn them off/on, and what settings I need to tweak, and why... Hopefully i can become self sufficient sooner or later.

the VCore is the voltage to the cpu put that at 1.25 when you do overclock

but before you do any overclocking tell me what cpu cooler you are using

sorry didn't see that

ok what are you trying to get like 4Ggz or 4.5Ghz or what

as much as I can lol :p 

Don't I have to play with DIMM timing, and other settings in BIOS before I play with clock speed?

no you don't need to mess with that

the cpu voltage or VCore set it to 1.25

then set the cpu bus speed/multiplyer to X44

then run Prime95 for about 15 minutes to test if it is stable

Sounds good. And if I want to get more out of it then I just turn up the multiplier right? And lets say the highest I can go is 4.7, do i just keep turning down voltage to get the lowest possible voltage for that OC or just leave it

yes the multiplyer and voltage is the key but no the more multiplyer the more the cpu will want more juice like X50 multiplyer you would want ~1.3 VCore
ProTip:NEVER I REPEAT NEVER GO OVER 1.35 ON THE VCORE

Ok right now I set the turbo multiplier to 48(4.8GHz) I left the DIMMs alone and I set the voltage to auto. The voltage is at about 1.34v right now, should I turn it to like 1.25 and see if its stable?

How come I shouldn't go past 1.35? Sorry Im such a nooby.

DON'T SET VOLTAGE TO AUTO
it overvolts your cpu yes set it to 1.25 the run Prime95 for 10-15 minutes to see if it's stable

If I set the voltage manually will it still undervolt when my CPU is not being used fully? Also I'm told some program called AIDA64 or something (Still googling for it) is a better tool for testing stability. Right now my CPU is running at 69C with BF3 b2k (The most CPU-stressful xpac of the game)

TIPS FROM A TECH:
*There are few, if any, games that will benefit from overclocking this CPU (unless you have a high-end CROSSFIRE/SLI setup).

So before I comment on overclocking, let's be clear:
1) overclocking usually breaks the CPU low-power profile so you'll get more fan noise, even in Windows

2) overclocking too high on some CPU's can actually disable one of the cores (haven't checked this one, probably drop to THREE cores around 4.3 to 4.5GHz)

3) RAM can be accidentally overclocked as well when overclocking the CPU resulting in stability issues.

**CPU overclocking:
1. peruse your motherboard manual (note: some motherboards have AUTO configuration features that are easier than others. the following is a MANUAL approach)

2. Change the BASECLOCK and CPU MULTIPLIER to get the desired frequency (i.e. 200MHz x 21 = 4.2GHz)

3. Verify RAM is still the proper frequency. If needed, adjust the RAM MULTIPLIER so it's correct again (i.e. 200MHz x 8 = 1600MHz)

4. SAVE, REBOOT and run MEMTEST ( www.memtest.org )

SUMMARY:
- overclocking provides no benefit to most or all games with this CPU
- will increase fan noise slightly (even on H100) in idle
- overclocking too high can actually disable one of the cores (not sure of details for this CPU)

*My advice is keep the stock settings which work great and keep your system cooler. If you have need of overclocking (converting video?) consider just doing it temporarily.

I've tested the benefits of overclocking extensively on many, many games with an i7-860 and GTX680 @1300MHz. I found just a few games that worked better but with your CPU there would be no advantage.

69C is pretty good because ivy bridge is usually 20C hotter than sandy bridge but Prime95 is a proven system i don't even know what AIDA64 is

Hey, if you want to do it right, don't start with a vcore of 1.25. My 3570k hit 4.6GHz stable at a vcore of 1.18 - the less voltage you feed it, the less heat it produces.
