Ok fairly new to all this and so have gone with the easy option.

Set the auto-OC to 4.6 and changed my ram timings to 1600mhz.

Question is do i need to do anything else?

Running a i2600k under a H100. Temps are very good, performance is ok after a few games to test stability.

I need to read sticky to understand Prime etc...but is that the best test etc?

As always appreciate any comments/suggestions etc.
 
Although auto OC is an easy way to get more out of your gear I wouldn't recommend it as it puts excessive amounts of voltage through your chip to ensure stability. Personally I would recommend that you revert back to default settings and read up as much on overclocking the sandybridge chips as possible. Once you understand what all of the settings in the BIOS do, have a go at overclocking yourself. You'll be able to achieve the same speeds but with far less voltage, resulting in increased power efficiency, lower temperatures and a longer life for your components.

PS: From what I've seen, Prime95 and IntelBurnTest are the most common programmes for stability testing.

Thank guys.

@buzz - Thanks for the link. I saw your vid as i was buying the asrock. I'll have a fiddle ;) and see how I get on.

I thought auto-OC seemed to good to be true, but an easy way to see what is achievable.
 
Hey guys. Doing some overclocking too on same mobo/cpu. Running P95 on blend with 8 tests atm. It has been running for about 30 mins now and with my Antec 920 on Extreme setting the cores hit about 66°C. On custom which has the cooling fluid at about 37°c and the fans at 1680rpm/41db the cores are between 68 and 70.

This was on a preset o/c to 4.6 and the memory clocked to 1600. Might try a custom o/c as the lower voltages might bring the temps down a bit. In general though are these acceptable temps for P95 on blend?

Deffo the better option, and to be fair in some ways sandybridge chips are in many ways easier to overclock than previous iterations where you had to fiddle with FSB settings which also increased your memory clocks in tandem - at least with sandybridge you can overclock cpu and memory separately.

Here is a link which I think keeps it simple but covers the necessary steps to safely overclock sandybridge - have a look at

hope this helps

I have been watching my overclock and actually had Prime running for 3 hours with no issues last night. But I do have some concerns about voltage. Everest is showing a Voltage: CPU Core of 2.0 and sometimes more but CPU-Z is showing a Core Voltage of 1.032. In the ASRock Extreme Tuning Utility (not using this to o/c, just monitor along with Everest and CPU-Z) the DRAM voltage is also showing as 1.65V.

Below is a desktop pic showing the info and at the time I took the screenie (10 mins ago ish), I was not running prime or anything other than desktop apps. As you can see from the Everest readings, the CPU Core is 2.06. Would appreciate some advice.

I plan to follow one of the guides but would this one work on the Extreme7?
 
CPU-Z core voltage is the reading to watch, don't worry about everest.

As for ram voltage, you should be able to lower it to 1.55v (or even 1.5) without any problems.
