512Mb A-Data DDR2-667 (PC2-5400) CL5 module by Adata

512Mb DDR2 667MHz memory module for desktop systems. PC2-5400 standard, 240 pins, non-ECC. CL5 memory module. Suitable for dual channel operation if installed in pairs.

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. 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.

Compared with DDR, DDR2 owns four key technologies pave the way to high-speed operation and low power consumption.
