    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 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.

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

    A dual inline memory module (DIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected to each other.

    240-pin fully buffered DIMMs (FBDIMMs) are used to provide DDR2 SDRAM memory for servers and motherboards that use FBDIMM technology, as opposed to conventional registered DIMM (RDIMM) technology. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast. FBDIMM technology utilizes an advanced memory buffer that allows modules to be connected in series — meaning that more memory modules can be connected (and thus memory density is increased) and errors at the connection points are reduced.

    Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or fully buffered modules).

    DDR2 240-pin fully buffered DIMMs are available in DDR2 PC2-4200 SDRAM and DDR2 PC2-5300 SDRAM.

    To use DDR2 memory, your system motherboard must have 240-pin DIMM slo...

      Comments about Crucial 4GB 240-pin DIMM DDR2 PC2-6400:

      The D5400XS motherboard does NOT support the full frequency of 800mhz, and shows only as 667mhz :(
