[i5 2500k] MSI P67A-G43 Overclock Help

post #1 of 5
Thread Starter 
Hi everyone, this is my first time posting on Overclock.net so I'm sorry if this is in the wrong section, I tried looking through all of the sections and didn't see one dedicated to "Intel overclocking" flame me if I'm wrong frown.gif

Anyways, I've recently built my first computer and was just had a few questions about overclocking.

As you probably know since you've read the title I have an i5 2500k CPU and an MSI P67A-G43 motherboard.

I'm a PC gamer who is going to be streaming a lot of VERY CPU + GPU intensive games at 1080p resolution so my 3.7GHz turbo boost just doesn't cut it. At least in my opinion it doesn't.

As it stands I've never overclocked a CPU before, so here are my questions:

I watched a video about this guy overclocking his i5 with a P67A motherboard similar to mine, and he did a TONNE of configuration. It kind of startled me how many things he was changing in the BIOS.

He changed things like; Green power cpu phase control, changed a tonne of RAM settings which I assume I don't really need to do (please correct me if I'm wrong), he disabled spread spectrum, he changed Vdroop to low-vdroop, the voltage, and the multiplier obviously, then the cpu IO voltage (I'm not even sure what the main difference between the IO voltage and core voltage is), he changed the Dram voltage after what seemed to be him overclocking his RAM and changing timings from 9 9 9 24 to lower ones, he then enabled c1e support, enabled intel c-state, and changed the package c-state limit to c6.

Out of ALL of those changes the only two things that I can say with confidence that I understand are; the CPU core voltage, and the CPU multiplier.

I was going to overclock simply by changing the multiplier and then the core voltage, but when I saw how many things had to be edited in order to run stable I got kind of frightened and decided to make this post in hopes of me not destroying my CPU.

MY SPECS:

i5 2500k CPU
MSI P67A-G43
Antec 520W High Current Gamer PSU
Hyper 212 Plus 1x fan

Current CPU temps:

Idle == 29-38-35-35C
Load == 46-54-54-50C

I guess I'd like a stable overclock that can handle real world applications and run stable 24/7. Is 4.5 too much for my current temps? if so is 4.2 GHz sufficient? And what voltages should I run, also if anybody could enlighten me about some of those things I mentioned earlier in the bios that would be lovely. I did do research on all of them, however, I'd still like a little extra clarification . I don't like jumping into things head first.

THANK YOU! for all of your help guys, I really appreciate it.

Is this all I need to do? http://www.tomshardware.com/forum/267178-29-questions-p67a

Or is there more to it than that?

1.c is for 32 bit OS's. Can't install, I'm on 64 bit win 7.
