The number of black components on a 240-pin DIMM can vary, but it always has 120 pins on the front and 120 pins on the back, for a total of 240. 240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high, though the heights can vary. While 240-pin DDR2 DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are approximately the same size, 240-pin DIMMs and 184-pin DIMMs have only one notch within the row of pins. The notch in a 240-pin DDR2 DIMM is closer toward the centre of the module. Because it's designed to deliver improved performance for demanding applications, FB-DIMM 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 FB-DIMM memory in those systems is quick, easy, and affordable. Crucial's FB-DIMM 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.
