First off I didn't write this guide.
Secondly this is mainly focusing the I series from intel.
Lastly I don't recommend OC on stock cooling system or for anyone unfamiliar with their computers BIOS features.
Also this isn't "THE" guide just a helpful one IMO. Covers most of the basics.
I posted it in another thread but just in case I'll post it here.
OEM or Brand name computers usually "Lock" their processors so it may not be possible for you.
