Apacer was founded in 1997. Two years later, it was ranked as the fourth-largest third-party manufacturer in the highly competitive global memory module market. Apacer's product line consists of memory modules and flash cards. Apacer is now a global digital storage provider offering a complete range of digital imaging storage devices.

In a previous review, we had tested Apacer's DDR2 PC4300 CL4 memory modules. This time round, we received something a bit faster, two 512MB DDR2 PC5300 modules, capable of running at 667MHz.

Apacer uses Elpida's memory chipsets in its Memory modules.
