Hi there.
I currently have a 333Mhz FSB Athlon 2800xp barton running with 1Gb of 333Mhz CAS2.5 Ram.
I have got my hands on 1Gb of CAS3.0 400Mhz Ram. All i wanted to know is whether I can run the Ram at 400Mhz without overclocking the 333Mhz FSB of the processor. I can see in the BIOS there are dividers but I havent a clue what settings to put them on.
Also I am after a simple modded BIOS that allows you to set 1T for the RAM. I have looked through all the BIOS mods on here and over sites but am a bit confused

A simple 1T on /off feature is all I am after.
Any help much appreciated.
