Foxoffire33,  The R610 does indeed support the E5645 processor. The svc kit for it is part # X9GTD, or the part for the processor itself is 01M26. Hope this helps 
Hello, I have a qestion about the supported CPUś for the Dell power edge R610. In the documentation of dell I didn't found it in the CPU list but it says also that is supports E55 and E56 series.  Does The dell power edge R610 support the Xeon E5645?  Best, Reinier de la Parra
