Today I received my 2 sticks of Corsair CMX256A-3500C2 256MB DDR433 PC3500 Memory w/Heat Spreader from GoogleGear

I have no idea what I do wrong but... I can't get my FSB more than 203mhz. I lowered the multiplier to x10, x9 or x8 (I have a 2400+) and I have set Vdmm to v2.9 and Vcore to 1.95v (up vcore to 2v) I still cannot get more than 203mhz. I have C1 showed on my p80 Debug LED with siren sounds. I tried just using one stick of RAM and try each stick on each ram slot. Same result, woudlnt even post.

Also, weird things happened if I tried to push the vcore more than 2.05v. PS/2 Key board will not work after that. I will have to disconnect the keyboard and ground it and then reset the cmos and wiggle the ps/2 port a bit then I can get it to work again.

Unfortunately, the best I can do now is 11x203mhz(stable) or 11.5x200mhz(unstable)

Any advice given will be appreciated.

*side note my 5v line is always above v4.92 when I set vcore to 2.00v
