If you try that BIOS and find it isn't quite working right, try the one in my sig. My RAM hated that BIOS and i'm not sure why, as lots of people had luck with it. With the one in my sig i'm pushing 233MHz 2.5-2-2-5 2.65v...that's PC3200 running PC3700 speeds at better timings and less voltage than most standard PC3700 lol.
There's a handful of modded BIOS's to try, one of them is bound to do you good. I think i've gone through 14 myself in the last few months...
