Intel Xeon E5-2652 v3 socket: LGA 2011-v3

What the Xeon E5-2652 v3 is

The Xeon E5-2652 v3 is an OEM Haswell-EP ten core for dual socket clouds on LGA 2011-v3. Intel set ten cores and 20 threads at 2.3 GHz base with turbo to 2.8 GHz. Twenty five megabytes of Smart Cache serve dense guests. Power is 105 W on 22 nm from September 2014. OEM marking means it ships in system vendor nodes rather than retail boxes, so firmware support follows the vendor matrix.

Ten cores with 20 threads pack virtual machines per socket for large deployments. Modest clocks hold power inside 105 W while cache covers many guests. ECC DDR4 guards data across long runs. No integrated graphics exist, with BMC for management. An SSD and network fabric shape node throughput more than peak clocks. Buyers encounter this SKU in used system pulls with vendor locked firmware.

DDR4 with ECC over four channels feeds each socket. Two QPI links tie dual nodes. The mix is a server socket for clouds that buy vendor systems where core density per watt decides cost.

Socket and motherboard compatibility

The E5-2652 v3 fits LGA 2011-v3 on C612 Grantley boards from its system vendor. OEM parts validate to specific vendor platforms, so cross vendor use may fail firmware checks. Confirm the exact system matrix before buying used pulls. Desktop X99 boards never take this server OEM part.

ECC RDIMMs over four channels carry memory. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so use vendor manuals for populations. Cooling follows vendor 105 W heatsinks with rack airflow.

A retail ten core on the same socket offers broader board support where vendor locks bind. Check stepping support before any swap.

Memory, PCIe and cooling

DDR4 ECC across four channels per socket suits dense guests. Populate evenly for NUMA balance. Registered DIMMs reach large counts. Speed steps with DIMM count per manual.

Forty PCIe 3.0 lanes per socket feed NICs and HBAs for cloud fabric. Dual socket placement should respect NUMA locality. Vendor manuals detail slot maps for storage controllers.

Vendor 105 W cooling handles sustained loads with front to back air. No retail cooler exists. Inlet temperature governs turbo residency during all core runs.

Upgrade paths

Within the socket retail ten core options with similar cache suit broader boards where OEM locks block use. The Intel Core i7-5960X is an HEDT alternative without ECC for single socket creation. Both need platform checks.

A larger platform means newer sockets. The E5-2652 v3 covers vendor cloud nodes where ten OEM cores at 105 W are the design point.
