L3 latency has alot more to do with NB speed than with CPU speed although both have an effect on it. 2.75ghz on both cpu and nb gives me 6.6ns, but with the same cpu but 2.5ghz nb it goes up to 7.2ns. Memory copy speed seems to be completely dependent on the speed of the L3, along with the read speed for the L3 being dependent on the read speed of the memory. Just wondering but whats the highest stable nb anyone's gotten here? I've gotten 2.8ghz, will be testing higher later today.
