  1. I recently built my first computer, but had a problem with my ram (as posted in another thread) i solved this by using ram from my (now) old computer, however i compared the boards, and found no reason y my new ram shouldn't have worked:

    ````````````````````````old board`````````````````````````````````
    Manufacturer Specifications - Elite Group (ECS) L7VMM
    * Chipset: VIA ProSavageDDR KM266
    * Max Unbuffered DDR SDRAM: 2048MB
    * Error Detection Support: Non-ECC only
    * Supported DRAM Types: DDR SDRAM only
    * Module Types Supported: Unbuffered only
    * Max Component Density: 512Mb
    * 184-pin DIMM Banking: 2 (2 banks of 1)
    * Graphics Support: AGP 4X
    ``````````````````````/old board```````````````````````````````````

    ``````````````````````new board``````````````````````````````````
    Manufacturer Specifications - ASRock 775i65G
    # Chipset: Intel 865G
    # Max Unbuffered DDR SDRAM: 2048MB
    # Error Detection Support: Non-ECC only
    # Supported DRAM Types: DDR SDRAM only
    # Module Types Supported: Unbuffered only
    # Max Component Density: 1024
    # 184-pin DIMM Banking: 2 (2 banks of 1)
    # Graphics Support: AGP 8X
    `````````````````````/new board``````````````````````````````````
    There seems to be no reason why my new ram should not work in my new computer? am i missing something?

    It`s quite possible the ram was incompatible with the mobo. Some mobo`s are far more tolerant of different brands of ram than others.

    Yepper - you basically are comparing boards that accept similar ram BUT you aren't comparing the ram.

    Lay out the specs for the ram like that with the latency numbers, etc.

    sorry i dont know much about ram, all i really know is the old 1 is pc2700, cl 2.5 (thats out from memory so may not be exactly right)
    and the new one is pc3200 cl 3
    but my board can take up to ddr400, which am i right in thinking is pc3200

    Yes, ddr400 is pc3200. Most mobo manuals or mobo manufacturers websites will have info on what brands/speeds/sizes of ram are recommended for any particular mobo. As I said earlier, some mobo`s are very picky when it comes to which ram they will work with, while other seem to be very forgiving.

    Regards Howard :)
