What the Xeon E5-4607 is
Intel Xeon E5-4607 is a six core Sandy Bridge-EP server processor that Intel released in May 2012 for entry quad socket servers. It runs at a fixed 2.2 GHz with no turbo, with 12 MB cache per ARK and Hyper-Threading for 12 threads. Power is rated at 95 W on a 32 nm process. The list and database entries claiming 15 MB are wrong; ARK specifies 12 MB, which is used here. The 4600 numbering allows four socket operation.
No integrated graphics are present. Memory is limited to DDR3-800 and 1066 over four channels with ECC. The chip gives 40 PCIe 3.0 lanes plus two 6.4 GT/s QPI links. Forty-eight threads across four sockets suit scale out virtualization at modest clocks.
Boards are four socket Romley designs with vendor firmware. Fixed clocks keep behavior predictable across the ring. The LGA, PGA and BGA: CPU package types explained guide contrasts this large socketed server part with soldered designs.
Socket and motherboard compatibility
The Xeon E5-4607 fits LGA 2011 in FCLGA2011 form. Quad socket Romley boards with the C600 series controller carry it. The vendor list must include the exact E5-4607 string with Sandy Bridge-EP microcode.
At 95 W per socket, chassis cooling must cover four populated sockets. The Socket vs chipset: what decides whether a CPU works guide covers server pairing.
Memory, PCIe and cooling
Memory support is DDR3-800 and 1066, four channels per socket, with ECC and registered DIMMs. Balance DIMMs across all four sockets for bandwidth.
PCI Express is 40 lanes of PCIe 3.0 per socket. Two QPI links at 6.4 GT/s join four sockets. NUMA tuning matters at this scale.
Cooling is vendor qualified for 95 W per socket. No retail mount exists.
Upgrade paths
Within LGA 2011 the Xeon E5-4607 can move to faster Sandy Bridge-EP or Ivy Bridge-EP four socket parts on the same board, where vendor lists allow. All sockets should match. Memory and storage carry over.
A platform move means a DDR4 multi socket generation. Keep the cluster for scale out duty.
