Bios Mods -The Best BIOS Update and Modification Source

I just received a Hp Compaq Elite 8000 sff running:
Core 2 Duo E8400 clocked at 3.0 ghz
8gb of 1333mhz ram
Western Digital 1Tb HDD
and BIOS Version V 01.14 Rev A (Found Here):http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=4066929&swItemId=vc_156854_1&swEnvOid=4132
OS Windows 10 Home Edition

I want overclock this Processor to 3.3ghz. If any of you people out there are able to do it, Thank you in advance

You can't overclock nothing on this PC.
Best regards.
