Brand New Never Opened  A-DATA 2GB 200-Pin (PC2 5300) DDR2 667 Matched Pair  %100 Genuine with Life Time Manufacture Warranty This is faster than 533MHz, These Modules Operates with High Bandwidth 667MHz     This Vitesta DDR2 667 SO-DIMM is designed to meet the 667MHz data-rate specification of the JEDEC (Joint Electron Device Engineering Council) standard, but it seems to own the huge potentiality to draw out higher performance in A-DATA laboratories. By 1.8V low-voltage application, DDR2 modules can reduce about 50% power consumption, which is compared with 2.5V (DDR) power supply on the same operation speed. So it is an environment-friendly product. To meet the graphics and multimedia demands of your Macintosh Intel powered. You will notice the difference right away.In order to achieve so amazing high operation speed, A-DATA applies the lower parasitic-loading FBGA (Fine-pitch BGA) package to run in full-speed without extraneous loading.
