Understanding CAS Latency
 

There is an excellent article on CAS latencies at Club Overclocker.

I suggest reading it if your choosing between that PC3500 Cas 3 and that PC3200 Cas 2.5.

pc4000 cas 2.5 here 8) -------- that article didn't teach me too much except that pc3200 ram sucks.. :P

so iguess PC2100 is unacceptable :/

very.. but not as bad as.. *gasp* pc1600...
