Wow! Obtaining 376 MHz at CAS 2 and 402 MHz CAS 2.5 at only 2.5V is very impressive for this large of a memory stick. Considering it only required 2.5V for 402 MHz, I'm sure this stick can obtain more...much more, unfortunately I may have to wait for the KT400s to come out to find out how fast this memory stick can go.
