Intel Xeon E5-2600, E5-2400 and E5-4600 Processors

Reading the E5 model number

The digits after "E5-" give the family and the version suffix gives the generation, and together they decide the server. Intel ARK lists E5-2600 and E5-2400 parts as two-socket and E5-4600 parts as four-socket; E5-2400 parts also use the LGA1356 socket with three memory channels per processor, where an E5-2699 v4 has four. Representative models from this listing, with Intel's specifications:

Intel ARK labels all four E5-2600 generations FCLGA2011, but Intel's socket reference separates LGA2011-0 for v1 and v2 from LGA2011-3 for v3 and v4, and the memory changes with it: v1 and v2 run DDR3, v3 and v4 run DDR4, so Dell builds the two pairs into different servers.

Matching E5 processors to servers

Dell specifies the R720 for E5-2600 and E5-2600 v2, the PowerEdge R630 and the R730 for E5-2600 v3 or v4, the R420 for E5-2400 and E5-2400 v2, and the four-socket R830 for E5-4600 v4. HPE's DL380 Gen9 QuickSpecs list the E5-2600 v3 and v4 families and allow a field upgrade from v3 to v4, yet rule out pairing one v3 with one v4 processor in the same server, so order matched CPUs. Pick a generation on the E5-2600 v4, E5-2600 v3 or E5-2600 v2 page, or step up to Xeon Scalable processors for 14th-generation PowerEdge and later.

E5 parts come with an Enterasource warranty whose length is printed on each product page. Other families are under Intel Xeon processors and server CPUs.
