3770k Overclocking question(s)

post #1 of 4
Thread Starter 
Hey folks,
Well, I managed to build my new rig and here are the specs:

CPU: i7 3770k
Motherboard: Gigabyte Z77X-UD3H
PSU: Corsair CX 600
RAM: 8GB G.Skill Ripjaw 1600
GPU: Sapphire Radeon HD 7850
Heatsink: Zalman 9700 (fan set to ~2100 rpms)

I have managed to OC the turbo to 4.3 Ghz @ 1.13v and my temps in Intel burn test are 68c, at idle they are ~29c.

My questions are:

At what voltage/oc will I affect the life of the CPU?
What temps are actually safe?
What is actually considered stable, is it after you have run Intel Burn Test on "standard" or is there another benchmark to go by?

I don't do much other than some Web Design and Gaming (like WoW and others)

I look forward to hearing from you guys because I feel like a total noob with this new tech.

Thanks

OC guide for Gigabyte boards:
http://www.overclock.net/t/1247413/ivy-bridge-overclocking-guide-with-ln2-guide-at-the-end

It will be much easier for people to help you with later posts if you have your rig in them, so you can follow the instructions here:

No one knows for sure what is 24/7 safe on an Ivy chip. I think most would agree that under 1.35v there is no issue, and above 1.5v you are taking a risk. In between those numbers depends on how you use the machine and what your temps are.

I like to recommend that people do not exceed 95c while stress testing Ivy, so don’t let any of your cores max temp hit that. For a 24/7 oc you should shoot for max testing temps in the 80s or lower, so your day to day temps are in the 60c or below.

Nothing is completely stable, and everyone here has a different definition. On the very low end 20 rounds of IBT on max, next would be 12 hours of Prime95, then 24 hours of Prime95 with zero WHEA, and last would folding for days on end. Hope that helps.

Hi justin,
Thanks for the reply. I did read one of the overclocking posts on the 3770k with a gigabyte board and while it was very helpful, it was somewhat over my head.

In a chart on. the thread he recommended a voltage of 1.25v for 4.4ghz but it seemed a little hot (77 - 82) on IBT testing. So I shut it down and lowered the voltage and ended up with what I have now. I am not used to having a chip that can reach over 70 so it kind of freaked me out. I guess now I am wondering if my voltage is too low to be consistantly stable.

You will probably need to read that guide a couple times, that is completely normal for someone new to this. The problem is Ivy chips run hot, and your Zalman cooler is not up to cooling it down to any great degree. The only way to address that if you want to get a high oc is to get a better cpu cooling system, which unfortunately costs more.

As I posted, your 82c is fine for testing. You will not know if 1.25v is too little or too much for 4.4 until you have done a lot of testing. In my opinion, you want to find the minimum vCore to get 4.4 stable for 12+ hours of Prime95 with no WHEA logger warnings. Once you know that number you can better assess your chips oc potential.
