Corsair TwinX1024 4400C25PT 1Gbyte Matched Memory

Whichever way you cut it, DDR550 memory is extremely useful when the only means of radically raising CPU speed, and by inference performance, is to crank FSB to 275MHz+. It would make a perfect partner to a setup consisting of, say, AMD's Athlon 64 3000/3200 and/or Intel's Pentium 4 2.8GHz/3.0GHz processors. These processors often overclock to 250MHz+ FSB with relatively innocuous cooling, and having synchronous RAM allows you to extract maximum bandwidth and performance from said setup.

Interesting as I was considering buying some of this the other day for a 754 system.
It does show what effect not only latencies but command rate have on performance.
Obviously 1 of the reasons that 754's can keep up with 939s is that it is quite common to be able to run 1T on TCCD at higher bus speeds e.g. 270 2.5-3-3.

1 thing - " By running memory in a synchronous fashion with an overclocked Front-Side Bus or driven clock, performance, as expected, is markedly better than opting for slower, asynchronous RAM."
Surely unless you are running LDT multi of 1 (unlikely I would have thought - more likely 3 or 4) then your CPU & RAM buses can't be synchronous?
