I'm looking at some Corsair value RAM (2x512M for $93). But Corsair also has RAM of the same specs for more than twice the price (1x512 for $106): As far as I can tell, the specs are identical, except for CAS latency (and they're both some variation on CL3), and the voltage is slightly different. What's the real difference between different "grades" of RAM from the same manufacturer with the same specs? Under what circumstances will any differences manifest?
