Early 2008 Desktop/PC 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 MacPro - running at speeds up to 3GHz - 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 MacPro 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 MacPro system, let Crucial help you find the right upgrade today.
