More about : memory timings bum_jcrules April 30, 2003 3:59:04 PM Frequency speed is still the main driver of the overall speed of a read/write cycle. 200MHz is technically ~20% faster than 166.667MHz based on the frequencies alone. The real world does not see that high of a return. However timings are important but not as important as the clock speeds. The different timings are... tCAS = Time for the Column Access Strobe tRCD = Time RAS to CAS Delay tRP = Time RAS Precharge tRC = Time for a cycle, random read or write; It equals tRAS + tRP 2:2:2:5 = tCAS : tRDC : tRP : tRC The lower the rating on each latency timing the better the memory is. Corsair XMS modules are a good memory to choose for DDR400/PC3200. <A HREF="http://www.millionmanlan.com/MMLDefault.asp" target="_new">Million Man LAN 2 is June 25-29, 2003 in Louisville Kentucky...
