Moreover, this comparison will hardly take a lot of time.
Therefore, we have every right to compare DDR3 and DDR2 SDRAM side by side here. In fact, it is true: DDR3 SDRAM is a sort of third reincarnation of DDR SDRAM principles. At slightly loosened timings (like those on the DDR3-2666 kit, at 11-13-13-35), this kit made it only two tenths of a MHz short of a CPUz validation of DDR3-2940. Sure, but how about max frequency? There’s nothing at all to complain about here. The '1333' speed reference pertains to MT/s (data rate) not MHz (I/O bus clock). The specs posted to the Sony website are incorrect in that it states the Type/Speed is DDR3/1333MHz.
