Thanks for your question. It looks like the fastest option available is the X5672, a 3.2ghz option.  Further research shows the board will accept up to 95w processors only.  The 3.4ghz option you are referring to is a 139w CPU.    Regards,
    I have a PowerEdge c6100 arriving soon.   It is a bottom end model with the Xeon 5520 processors. For the majority of what this server will be used for, that is more than enough. But for one blade the application in it will vastly benefit from a higher frequency rather than multi-cores. Doing a quick check I found that the 5520 is a socket 1366.  But when I check spec sheets for the server it mentions only the 5500 and 5600 series processors.  A little more digging shows that those 2 series were just factory options.   To my question: Is this server ~ONLY~ compatible with the 55/56 series processors or is it compatible with anything that fits the socket so to say?  Before I spend another grand on 2 CPUs with 3.4 Ghz I would like to know if they would work!  ~Thanks ahead of time, Tony
