Will this Processor work with this Motherboad:

I want to buy an Intel Core 2 Duo E8400:

But i need to know will it work with my motherboard: MS 7318 ?

More about will processor work motherboad
  1. Yes, they are compatible. That board has an LGA 775 socket.
  2. They are NOT FULLY compatible!
    Your motherboard (MS-7318) uses VIA PT890 series chipset which supports maximum FSB of 1066MHz.
    Core 2 Duo E8400 is the second generation of "Core 2" family. It has clock speed of 3.0GHz and FSB of 1333MHz so it runs at the multiplier of 9x.

    There are two possible problems:
    1) Your computer won't boot at all because your motherboard BIOS is very old so it may not recognize your new CPU.
    2) Your computer will boot but your new CPU will run at lower clock speed of 2.4GHz.

    The first problem can be solved if there is BIOS update for your motherboard which you have to get from your computer vendor.
    But when it recognizes your new CPU, you will experience the second problem because your motherboard cannot handle FSB over 1066MHz.

    So there are two suggestions for now:
    1) If you can't solve the first problem then the only compatible CPUs for your motherboards are Core 2 Duo E6x00 series (e.g. this and this).
    2) If you updated your BIOS and it can support this newer generation then you can get Core 2 Duo E7x00 (e.g. this and this) or Pentium Dual-Core E6x00 (e.g. this and this).

    With some more research, it looks like VIA PT890 series chipset won't accept any 45nm Wolfdale-based CPUs at all, including Core 2 Duo E8x00 & E7x00 and Pentium Dual-Core E6x00 & E5x00.
    See my post here for more info.

    Good thing we had your eyes on this, I read the first part, glanced at his CPU-Z dump, and then checked compatibility for his motherboard and the E6300...so fail. :) :)
  4. ^ Thank you! :)
    Took me a while to research, though. Never heard of MS-7318 but later found out that it came from Medion PC MD 8822.
    Also found that new BIOS update is available so I'm updating my previous post now...
  5. does that mean now my motherabord can take this processor?
    if yes, why
    if no, why
    what processors will it be able to take?
    thanks in advance
  6. You need to check visualy your motherbaord and find the reel model because MS-XXXX is for MSI engineering only.

    With your reel model, we can show you the website and tell if yes or no your cpu is compatible with upgraded BIOS or not.

    With some more research, it looks like VIA PT890 series chipset won't accept any 45nm Wolfdale-based CPUs at all.

    45nm Wolfdale-based CPUs are:
    Core 2 Duo E8x00
    Core 2 Duo E7x00
    Pentium Dual-Core E6x00
    Pentium Dual-Core E5x00
    Celeron Dual-Core E3x00

    According to MSI's own PT890 Neo (which uses the same series of chipset) details, it also gives a hint that it can't support any CPUs newer than 65nm Conroe-based (Core 2 Duo E6x00) CPUs.
    See here for the full list of compatible and incompatible CPUs.

    Now, unfortunately, the answer is: no, it will never take E8400.
    The best CPU you can get is Core 2 Duo E6700. It's the same generation as your current (E6300) CPU so it's 100% compatible.

    Sorry for the wrong assumption before and hope this helps (again!) :)
