Overclocking How is overclocking done on this mb?

There are many issues to consider when overclocking and the first is to be sure that you have extra cooling for your processor. On this motherboard I do not recommend overclocking but since ASUS says that it can be done I will try to give you some places to get information on your A7V880 system. If you do not have your user's manual, you can go to the link below and download one.

Refer then to section 2.4.5 on pages 2-21,22 of the User's Manual for Jumper Free configuration overclocking settings. In BIOS Setup I suggest a CPU Multiple of 10 or less. If you choose to use the AI Overclock Tuner instead, a setting of [Overclock 20%] or less would be best. The VCORE Voltage setting will depend on the specs for the CPU that you are using. If you don't know leave it at Auto. As I said before, overheating of the CPU is a problem in overclocking and you can monitor the temperature via the Hardware Monitor. Refer to section 2.5.6 on page 2-26 of the manual. Modern cpu overclocking normally does not exceed 20% safely unless you are willing to spend a lot of money on liquid cooling and frequent replacement of damaged processors. I would be interested in hearing whether you decide to overclock or continuing with your present settings.
