Getting more speed out of my ram :D

I have a p4 2.4b.

At the moment because of my slow PC2100 ram i can only overclock to 2.8ghz without my pc crashing before windows etc etc. Is there anyway i can get this ram to go any faster? ive tryed upping the voltage etc! Im pretty sure i have the ram timings in the fastest order ie 2.5 2 2 6 or something

Try relaxin the RAM timings which means raising them

u mean higher numbers ??

yea the higer the ram timings are the more relaxed they are

Nothing else i can try??
