Just some interesting things from changing the command rate.

Apart from obviously T1 is quicker in the memory...the L3 latency is less, anybody know why?

Tighter timings and command rates result in reduced latencies...

lower latency is better m8 :)

mmm didn't know CPU cache was affected by that stuff.

mem performance has massive effect on cpu performance m8y :)

I would say L3 being the larger of all 3 cache levels is reliant on being filled/serviced from Main memory the likely hood data moving in/trashed would be greater than instuctions in the L2 & L1 that would hold a greater relivance to the CPU.

If that makes sense.
