Windows 7: Manual OC or AI Suite on ASUS P8P67-M PRO

Hi
I have the following board ASUS P8P67-M PRO plus Intel Core i5-2500K 3.30GHz which i bought already overclocked to 4.8ghz as a bundle deal, i started to get BSOD a while back so took PC back and after ten days testing they told me it was a faulty power supply, which i replaced got PC and all was find, but the a couple of days ago i started to get random BSOD & system crashes, i have posted my dump files and it been analysed and put down to un stable over clock, so now i just want to down clock to something more stable and wondered what would be best, manual OC or using AI Suite and doing on the fly through windows?

is there anyone with the same board that as a stable OC that doesn't might posting there bios settings here?
thx

I never did have any luck doing any clocking except using bios with Asus Express Gate.

make that two us now, tried to copy something that some one posted on another site with no joy, it seems i had i faulty board & cpu, all is well again for now...LOL

Copying someone elses settings is no garantee..all boards/cpu's etc will clock differently.

Best way to overclock is to do it in BIOS. It allows far greater fine tuning than using manuf supplied overclocking suites.

Manual and make sure you have read up enough to know what you are doing. A lot of the auto overclocks raise voltages too high IME, but some of MB autos nowadays are claimed to do better. Myself I read up on the board and chip and when I fully understand the safe limits, then I manually overclock. You then have to experiment to see where your specific CPU is stable - within the limits of the chip. And don't trust what the operating voltage limits are from Internet posts. Look at the Intel/AMD chip specification documents. Trust me, the school of hard knocks can be expensive.

Listen to GeneO.

I used the automatic overclock on my ASUS P8Z68-V Pro and it got me to about 4300MHz on my (stock 3400MHz) 2600K. It also ran my CPU voltage up to 1.58.

When I set everything manually I was able to hit ~4700MHz (stable) with the voltage at 1.37. You can imagine the corresponding lowering in my temperatures at the lower voltage, too.

Also, I never had any luck at all with the ASUS AI Suite. It took a lot of massaging to get it to install and it didn't get me very far at all. I'll admit that I didn't mess with it long enough to really try it out, but for me it just wasn't worth it. Others may have better luck than I did, though.

As everyone else has stated, if you can help it, do it manually. But research your motherboard and ram etc, to see what you can do with it. As its been said already, the programs aren't really the best and can damage your components.
