What the Xeon E5-2673 v3 is

The Xeon E5-2673 v3 is an OEM Haswell-EP twelve core for vendor clouds on LGA 2011-v3. Intel set twelve cores and 24 threads at 2.4 GHz base with turbo to 3.1 GHz. Thirty megabytes of Smart Cache serve dense tenants. Power is 105 W on 22 nm from September 2014. OEM distribution ties firmware support to vendor system matrices rather than retail channels.

Twelve cores consolidate virtual machines per socket at modest power. Base clocks hold all core work while turbo lifts single thread steps. Large cache trims memory waits across guests. ECC DDR4 guards data through long runs. No integrated graphics exist, with BMC for management. Fabric and storage shape node throughput alongside cores. Used buyers meet this SKU in vendor pulls where generic board support varies.

DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for clouds that buy vendor nodes where twelve OEM threads at 105 W are the design point.

Socket and motherboard compatibility

The E5-2673 v3 fits LGA 2011-v3 on vendor C612 Grantley systems. OEM stepping validation may block generic boards, so confirm the system matrix before purchase. Desktop X99 never accepts this server OEM chip.

Memory is ECC RDIMMs over four channels. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so follow vendor population rules. Cooling uses vendor 105 W heatsinks with rack airflow.

Retail twelve core E5 v3 offer wider board support where OEM locks bind. Verify microcode before cross vendor use.

Memory, PCIe and cooling

DDR4 ECC quad channel per socket suits dense guests. Even DIMM maps protect NUMA fairness. Large RDIMMs reach high counts. Speed steps with population per manual.

Forty PCIe 3.0 lanes per socket feed NICs, HBAs and NVMe for cloud fabric. NUMA aware placement across QPI links matters at twelve cores. Vendor manuals detail slot maps.

Vendor 105 W cooling sustains all core loads with cool inlets. No retail cooler exists. Turbo residency follows per core states and inlet air.

Upgrade paths

On the same socket the Intel Xeon E5-2670 v3 with twelve cores offers retail availability for broader boards. The Intel Xeon E5-2680 v3 with twelve cores is a higher clock retail step. Both need platform checks.

Newer server sockets replace Grantley. The E5-2673 v3 covers OEM clouds where twelve cores at 105 W are specified.
