DDR 2 667 MHz vs DDR 533 MHz

DDR 2 667 MHZ is very useful in playing games. When installed as two 512 MB ram, its efficiency will be too good .the speed comes from two rams and so the power is enormous.

DDR 2 533 MHZ is not up to the mark .it’s a basic DDR 2 rams. The efficiency is not so good but will come up with core 2 duo processors.

So prefer DDR2 667 MHZ while buying systems.
