Crucial PC3 10600 3x2GB Kit @ OC Club

"As delivered from Crucial, the latencies on this set of modules are 9-9-9 at 1333MHz. This, of course, they will do at 1.5 volts. Surprisingly, they do 7-7-7-20 at 1333MHz at 1.58 volts as well. Running at 7-7-7 was nice at the bottom end but the modules didn't get too much further without big volts until the CAS latency was increased to 8."
