    Well, my dad is pretty experienced in building computers, but he's having trouble helping me pick which type of RAM to purchase. We're building my own computer, and we've got everything but the RAM ordered. We know that the motherboard requires DDR3 memory, and not DDR2, but we don't know how many MHz the RAM should be. For those who would like to know the type of CPU, it is a Phenom II x4 945 (4 x 3.0GHz - 8MB Cashe - 4000 FSB), along with a Gigabyte M68MT-D3 motherboard. I'm looking at RAM, but it comes in MHz amounts of 1066, 1333, 1600, 1800, and 2000. If it matters, I intend on getting two sticks for 2GB each, totalling 4GB. Any help would be appreciated! Thanks in advance.

    Number of Memory Slots 2×240pin
    Memory Standard DDR3 1666+/1333/1066/800 ((Supports DDR2 or DDR3---- hmmm then must have two notches in RAM slots, something I have yet to run into but I don't know how else it run either type unless....it has two types of RAM slots on there))

    Wiki says this>>>> DDR3 DIMMs have 240 pins, are electrically incompatible with DDR2 and have a different key notch location

    In computing, DDR3 SDRAM or double-data-rate three SDRAM is a modern kind of dynamic random access memory with a high bandwidth interface. It is one of several variants of dynamic RAM and/or associated interface techniques that have been used since the early 1970s, and it is not directly compatible with any of the earlier types, not even with DDR2 SDRAM. This is due to different signaling voltages, timings, and other factors.

    Maximum Memory Supported 8GB PC3-8500 <<<maybe with a 64-bit operating system it does
    Channel Supported Dual Channel

    240-pin DDR3 DIMM Banking: 2 (2 banks of 1)
    Chipset: nVidia nForce 630a
    DDR3 SDRAM Frequencies: PC3-6400, PC3-8500, PC3-10600 and PC3-13300
    Error Detection Support: Non-ECC only
    Graphics Support: PCI Express x16
    Max Unbuffered DDR3 SDRAM: 8192MB
    Module Types Supported: Unbuffered only
    Supported DRAM Types: DDR3 SDRAM only
    USB Support: 2.x Compliant
    Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

    That info is found> http://www.newegg.com/Product/Product.aspx?Item=N82E16813128454

    down the page a bit under : "Check the Specs" button and then look at "Memory" specs
