4GB, 240-pin DIMM, DDR2 PC2-5300 memory module

FBDIMM for Apple Mac Pro

Note: Because Crucial carries modules with more than one design of Apple-approved heat spreaders, your module may look slightly different from the example shown above.

Because it's designed to deliver improved performance for demanding applications, FBDIMM memory tends to run at a higher temperature when compared with other DRAM. And that stands to reason as the Mac Pro is the fastest Mac system to date.

Now, upgrading the FBDIMM memory in those systems is quick, easy, and affordable. Crucial's FBDIMM modules meet Apple's unique standards for the Mac Pro systems, including a highly engineered design featuring heat spreaders that dissipate more heat faster, which allows for lower noise levels because the fans can run slower. So if you're a Mac user who wants to maximize performance on the Mac Pro system, let Crucial help you find the right upgrade today.

(Please note that FBDIMMS must be installed in pairs.)
