What the Xeon E5-2450 is
Intel Xeon E5-2450 is an eight core Sandy Bridge-EN server processor that Intel released in May 2012 for mainstream dual socket servers. It runs at 2.1 GHz base with turbo to 2.9 GHz, with 20 MB cache and Hyper-Threading for 16 threads. Power is rated at 95 W on a 32 nm process. Eight cores with DDR3-1600 support made it the density choice of the EN launch.
No integrated graphics are present. Memory spans DDR3-800 to 1600 over three channels with ECC, and the chip provides 24 PCIe 3.0 lanes plus one 8.0 GT/s QPI link. Sixteen threads with a large cache suit virtualization hosts with many guests.
Boards pair it with registered DIMMs in 2U chassis. The wide turbo range helps both all core throughput and single threaded management tasks. The LGA, PGA and BGA: CPU package types explained guide contrasts this socketed server part with soldered designs.
Socket and motherboard compatibility
The Xeon E5-2450 fits LGA 1356 in FCLGA1356 form. C600 series Socket B2 boards on the Romley-EN platform carry it. The vendor CPU list must include the exact E5-2450 string with Sandy Bridge-EN microcode.
At 95 W full size heatsinks with chassis airflow apply. The Socket vs chipset: what decides whether a CPU works guide covers server pairing.
Memory, PCIe and cooling
Memory support is DDR3 at 800, 1066, 1333 or 1600 MT/s, three channels, with ECC and registered DIMMs. The 1600 step helps sixteen threads share bandwidth. Full population matters.
PCI Express is 24 lanes of PCIe 3.0 per socket for Ethernet and RAID controllers. The 8.0 GT/s QPI link joins pairs. Place I/O near its socket on NUMA boards.
Cooling is vendor qualified for 95 W. No retail mount exists, so replacements follow the chassis vendor.
Upgrade paths
Within LGA 1356 the Xeon E5-2450 can move to faster Sandy Bridge-EN or Ivy Bridge-EN eight core parts on the same board, where power allows. Memory and storage carry over. A higher clock step is Intel Xeon E5-2470 at the same power.
A platform move means a DDR4 generation. Keep the node for dense guest duty where sixteen threads still pack well.
Frequently asked questions
