Just put together my system. Loaded all my software and followed NickN's guide to configuring both Windows 7 and FSX to the letter. Now I'm ready to OC, but have no idea where to start. Thanks. Dan Cole

The one I found is for the P67 but I think it would be fine for the Z68:http://www.clunk.org.uk/forums/overclocking/39184-p67-sandy-bridge-overclocking-guide-beginners.html

Here's another site - http://www.legitreviews.com/article/1615/14/ but Andrew is correct as your board is basically the same as the P67 ASUS board. They both use the same BIOS too. I would go into the BIOS and hit the "Extreme" button on the right and let ASUS do the overclocking for you. It should get you overclocked to 4.4 or 4.5GHz. I had issues doing that as it did not make the correct settings for my memory and I had crashes. It may work okay for your system though and it's worth a try. If it crashes, simply go back into the BIOS and return the system to normal. There are some BIOS settings pinned at the top of this forum that you might want to look at too. Good luck!

The clunk guide is nice... here's some more P67-based ones (basically the same) http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/1 http://hardforum.com/showthread.php?t=1578110

OK. I folled the 'Clunk guide" to he letter and got a blue screen. System's brand new, followed NickN's guide to th letter and ran both Prime95 and Intel Burn test, which showed it to be stable. THe recommended solution was to ncrease the Vcore. My question is: How much? The recommenedettingsare 120 and I tried 1.30. Just don't know where to go with this.
