Also we are done with TRD (thanks the Intel gods ) and the tricks motherboard manufacturers played to get boards doing silly FSB...as if FSB at 2400 matters :shakeshead:

I think we are dawning on a new fresh memory overclocking day with i7...yes some will push 2000mhz, some will think the read bandwidth is the be all and end off of benches, those who are clever will look to real tight access latency and huge write/copy speed.

1333 5-5-5- or 6-6-6- is where I hope to be, or even 6-5-5- and 1.6V or so.

I have the boards, just need the CPU now
To add on to Tony's message, all I can say is that properly setting up a i7/X58 system at DDR3-1554 CAS6 (1.65V, 6GB) resulted in memory copy and latency numbers that were significantly better than DDR3-1866 at CAS9 (1.7V, 6GB, CAS8 is not stable yet). In fact, CAS5 at 1333 is just stupid fast for the "majority" of users.
