read your motherboard manual to find out how.
You dont even say what board you have.

Your Rocketfish PSU has been measured. It has been weighed. And it has been found wanting.
Check it out on hardwaresecrets.com. Then replace it before it takes anything out.
To answer your question, there may be a key combination (e.g. Alt-F1) to unlock additional areas of the BIOS screens. This should be in your mobo manual.

Once you have tripped the JOC1 jumper on the motherboard to green (while the computer is off) go back in to the bios, when you highlight the memory voltage use your Page UP and Page Down key. By the way this is an XFX motherboard they never come with complete instructions, I don't think anyone there understands english well enough to write a proper manual. They are just as bad when it comes to replying at the support site, I speak english, I don't know what language they listen.

Why would you want to do that?

Running your ram at a 1:1 ratio is the most stable and making it to 1000 mhz would change that.

its locked cuz the jumper JC01 is in 2-3, put it in 1-2, I found this out at the bios cell menu. I also have the same mobo as you have.

Run the FSB to memory at 1:1. In other words run your memory clock at twice the FSB. You will not gain anything useful by trying to overclock the memory. And apparently, if Windows doesn't load, it's not working anyway.
