UEFI BIOS

Probably the best OC'ing article for the i7-2700K, i7-2600K, or i5-2500K is Clunk's -> http://www.clunk.org.uk/forums/overclocking/39184-p67-sandy-bridge-overclocking-guide-beginners.html Note ONLY those aforementioned CPU's can OC!

In general, the most successful CPU overclocks Stock~4.5GHz are with the idea "Less is More" and Clunk's is the easiest to follow. Note, vCore voltages vary from CPU to same CPU - none are 100% the same. Don't exceed 1.45v vCore even with a good aftermarket HSF, and best to stay 1.35v~1.42v vCore max. Yes, I know Clunk says 1.35v and it depends on the TEMPS; low temps + 1.45v vCore = OK vs high temps + 1.45v vCore = BAD. Stock Intel HSF = BAD.

Further, I won't OC the CPU too much with the stock Intel HSF, you don't want to overheat the CPU, and for the money I'd look at the Cooler Master 212+ -> http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065

Use Real Temp to keep an eye on your core temps and with a stock HSF I won't exceed 65C~70C becuse the spikes are +5C~10C and the stock HSF isn't equipped to deal with them as safely -> http://www.techpowerup.com/realtemp/

RAM for (1) kit is simple, AI Overclock Tuner -> XMP.

Overclocking a GPU use MSI Afterburner -> http://event.msi.com/vga/afterburner/download.htm then make small increases to the 1. Clock and 2. RAM frequencies. Test with 3DMark11 - http://www.3dmark.com/3dmark11/

thanx alot! wat are the default settings of the UEFI BIOS of this mobo Z68 vpro! i thnk io got it overclocked! 80degrees! i just want the default BIOS Setings or safe operating settings as well as default CPU frewuency!

80C is hot, you need an aftermarket HSF. The Default settings are (F5), then (F10) save and reboot.
