What CPUs are compatible with the Xeon E5 2620 using the x79 chipset (LGA2011)

I have a Dell Workstation with a 6 core 12 thread Xeon E5 2620 in it. It has a pretty slow 2.5G Max frequency. Since most of the apps I use for work are single tread, I want to see if I can swap it out for a faster CPU with less cores. It almost looks like the Xeon E5 1620 would be a good choice because it goes to 3.9G max. Can I just go swapping CPUs (assuming the heatsink is good for the higher power..) ? Will I run into any BIOS problems if I just swap out a Xeon from the same family as listed here: http://en.wikipedia.org/wiki/LGA_2011 ?

What about the non server chips? If I try to stick a Sandy Bridge-E or Ivy Bridge-E in a Dell workstation that was setup for server chips, would it just work or am I asking for a compatibility disaster?

  1. What workstation is it exactly? CPU compatibility depends on its mainboard and BIOS. You have to look for its specs, which will hopefully tell you what is supported.

    I suspect that E5-1620 would work, being the same generation CPU. If you want higher clocks, 3930k and 3960x seem like good candidates, if you don't need a lot of RAM.

    35W more of heat output is a significant increase. Your current cooling will be strained more. However if you use mostly single threaded apps, it should not be much of a problem.
  2. Hi
    Yep it looks like single core score it better on 1620 than 2620

    But to be able to check what CPU can you swap in you DELL Workstation we need you model or you Dell Tag.
    I`ll NOT risk with any LGA2011 CPU - you will not POST if you DELL bios is not supporting the microcode of the new one .....
  3. The Machine is a Dell Precision T5600 Workstation

    It is a 0Y56T3 motherboard
    BIOS is A04 07/05/2012
    It has the x79 chipset

    I'd like to get the highest GHz I can, and it doesn't need to be the Ivy Bridge E stuff..

    This are supported CPU`s on you T5600

    Intel® XEON_8 (E5-2687W, E5-2680, E5-2665, E5-2650)
    Intel® Xeon® 6-Core (E5-2667, E5-2630, E5-2620)
    Intel® Xeon® Quad Core (E5-2643, E5-2603, E5-2609

    The fastest CPU is the E5-2643 - 3.30GHz/4-core/10MB/130W
    You know that the prices are killer .... :)
