Help with FSB:RAM ratios

Hi guys, can someone tell me how I can change my FSB:RAM ratio from 2:3 to 1:1? I'm not sure what memory options I should be changing under BIOS when I hit CTRL+F1. Supposedly this is what is preventing me from overclocking my FSB higher than 365. I'm using a Corsair XMS DDR2-800 (2x512) along with an E6300 on this motherboard. Any help would be very much appreciated guys!

Furthermore, I'm using the latest official BIOS from Gigabyte...but I heard there's an F4E floating around? What's the difference between the two?

what's your board?

Sounds like the DS3 possibily.

Also the F5 BIOS was released yesterday, I'd snag that one and try again.

you dont need the hidden options you get from ctrl+F1 just the MIT tweaker where you set the fsb and set the ram to run at 2 gigabyte speak for 1:1.
