hi, i have got a stick of pc2100 ram(256mb) and just ran cpu-z

are those timings any good,what do they mean? is that i good overclock for generic pc2100 ram?

thanks :)

the lower the numbers the tighter(faster)the mem timing will be,cas latency would have the biggest effect on performance,the tightest you should be able to get them would be,cas - 2.0,ras to cas - 2,ras - 2,tras - 5.best bet would be to change one at a time and check with memtest after each change to check for mem errors,might be worth running sandra mem benchmark before and after to see how much of an improvement you get:)
