New to overclocking; need advice.

post #1 of 5
Thread Starter 
Hello. I'm new to overclocking, but I don't find it very confusing to follow the directions and understand what the things like the voltage offsets and CPU multiplier do. I believe I should list the relevent parts I use before I go into any further detail, though in no particular order. If I've missed something, please let me know:

ASRock Z77 Extreme4
i5 3570k
That Hyper 212 Evo CPU fan/heatsink thingy and IC Diamond 7 to go along with it.
1 stick of Corsair Vengeance 8 GB
Corsair 650 TX PSU
My case is a Fractal Design R4 w/ Window, and the fans that the case itself came with are set to the highest power - 12 volts, I think it says next to the slider? I included this because I don't know if the fans help the CPU at all, though they would reduce the overall temp inside the case, right?

I followed this guide up to the "Starting Off" point, and so far the 5-minute Prime95 torture tests haven't given any errors while using the recommended custom settings up to a 45 multiplier, so 4.5 GHz. The voltage hasn't been adjusted from the 0.004 Turbo/0.005 Offset, and the highest I've seen it hit in CPUZ was 1.192. It went up by increments of 0.008, though, but I'm not sure how that factors into this. The temperatures of my four cores never exceeded 65 degrees Celsius, according to that RealTemp tool, and that was with a small spike of about 5 degrees Celsius above normal with a multiplier below the most recent one I've tested. The current test came up with around 60 to 63 degrees celsius, which seems fairly uniform to me, but I don't know of anything to compare this to.

Before I go any further with this, I'd like some input on how my CPU is compared to the majority of others in terms of overclocking. I would like an explanation on Load Line Calibration as well, and what it should be set to. If there's anything else I should be testing or doing, that would be nice to know.

I'm not entirely sure if this belongs here, or in the ASRock guide thread, but I figured this would be more noticeable as its own thread.

EDIT: Forgot to add that my LLC is set to 2 and that I'm using the setting where the clock speed drops to around 1.6 GHz when idle.

EDIT2: I bumped up the turbo boost voltage to 0.008 (one increment up), and Prime95 ran successfully with no errors at that 1792 setting along with 4 gigs of RAM (half of my total) used for 2.5 hours before I closed it so I could do school work without interruption. Temps hit 78 celsius max.

I saw something about using 90% of my RAM, though. Should I see how long I can go with 90% before trying anything else strenuous?

You look like you have the general idea. You should run Prime95 for at least 6-12 hours for 100% stability. It can fail at an hour, 3 hours, 4 hours etc. Sometimes, even 30 minutes.

For 4.5ghz, you'll need a bit more voltage. 4.5ghz can be hard to get, but it is do-able. You're temperatures are completely fine. Anything above 80 is not good.

Here is a guide for Ivy Bridge. It's based off Asus motherboards, but you get the same general idea. The creator of this guide (Swag) is a really smart kid. I think he's like 16 or 17. If you really need help, he can go on Skype with you to make it easier to explain what certain things are. Check it out.

Thanks for the advice. I have to get up in around 7 hours, so having it run while I sleep couldn't hurt, right?

EDIT: So by more voltage, do you mean the offset or turbo? I'd imagine it's the offset, but one can never be too careful with this.

Yep that's fine. Run it for 20 minutes to make sure temps don't go above 80. Once it hits 20 minutes, the temperatures stay around that range then you can sleep.

EDIT: Need a bit more advice.

Here's hoping that since at the time I made this edit this thread was still on the front page of the board, this line will be displayed first and someone will notice. :|

Original message: Thanks again, then.
