Maximum cpu upgrade for Optiplex GX620 USFF ?

This question has suggested answer(s)

Hi, does anyone know if an Intel® Pentium® Processor Extreme Edition 840 will work in a GX620 ultra small form factor?  I have one from a pull from a dead Precision 380.  If not, would it work in a GX620 minitower (bigger heatsink, etc)?  Thanks in advance.  Here's a link to the processor: http://processorfinder.intel.com/details.aspx?sSpec=SL8FK#

  • My 945-SL9QQ Bios A11 didn't start.  No diagnostic light just fan.

  • None of the High end CPUs will workon usff because the POWER SUPPLY is too small and the faster cpu's used the Copper block heatpipe heatsink

    not the aluminum one.

  • It is the copper block heatpipe heat sink.  

  • Better Heatsink does not make a 150 to 180W power supply suddenly provide 375W of power.

  • The processor is 93W not so high

  • i have a pentium d 950 3.4ghz and it works fine. i wonder f the 960 works? and also the pentium e. i have a e5400. will it work anyone? thanks in advance

  • That's a Wolfdale CPU and it won't work in the GX620.

  • thanks. i knew it at the back of my mind. but i was just hoping. :-(

  • I hear even the old E6300 (Conroe) is not compatible with the GX620.

    I'm planning on finding this out for myself.
