Upgrade Optiplex 745 with Quad Core

This question is not answered

I have two Dell Optiplex 745 desktops.  They came with Pentium D Dual Core 2.8GHz.  Can this LGA 775 motherboard take Core 2 Quad Core Q6700 processor?  The Q6700 is 1066 MHz with 8M cache.

    Core 2 Quad processors are not supported by the Optiplex 745.

  • I talked with Dell support.  They said the motherboard will support a max. 3.2 GHz processor.  The Q6700 is 2.66GHz with 4 cores.  Dell support said that means it has 4 x 2.66 GHz which is > 3.2 GHz.   Not sure what that means.

     

    Some people (Tom's hardware) have commented that they could use Q6700 but might need extra 5.25 PSU.

     

    Any ideas or suggestions?

    Latest Bios would be recommended BEFORE trying any new processor.

     Dell OptiPlex System BIOS, 2.6.4 ------------- [check for the current latest version]

    No Wolfdale's or Yorkfield's.
    Conroe/Allendale C2D or Kentsfield Quads only.


    I have seen people stated that Q6600 is OK, which is Kentsfield. So take a look below

    So, do you want an experiment with Q6700 or get Q6600, which most likely works?
