Intel Xeon E5-2693 v3 socket: LGA 2011-v3

What the Xeon E5-2693 v3 is

The Xeon E5-2693 v3 is a Haswell-EP engineering sample twelve core on LGA 2011-v3 that did not reach retail. Listings place twelve cores and 24 threads at 2.8 GHz base with turbo to 3.4 GHz. Thirty megabytes of Smart Cache match the twelve core v3 line. Power is listed at 160 W on 22 nm in the 2014 family window. The ES tag marks pre production silicon for vendor testing rather than general sale.

Engineering samples exist so vendors can validate boards and firmware before launch. Clocks and power on ES parts may differ from any retail counterpart, and microcode support stays limited to test platforms. No integrated graphics exist. ECC DDR4 over four channels feeds test nodes with two QPI links between sockets. Collectors meet this SKU in sample listings rather than vendor servers.

Because it never reached retail, board support is narrow and firmware dependent. Treat any working sample as a test part with uncertain longevity. Production twelve core E5 v3 cover real deployments where support matters.

Socket and motherboard compatibility

The E5-2693 v3 fits LGA 2011-v3 physically on C612 Grantley test platforms. Retail C612 firmware generally lacks ES microcode, so most production boards reject it. Vendor test matrices decide the few working combinations. Desktop X99 never accepts this sample.

Memory follows the Grantley pattern with ECC RDIMMs over four channels on test boards. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so sample use follows vendor test notes. Cooling needs 160 W capable heatsinks with strong airflow.

A production twelve core such as the Intel Xeon E5-2690 v3 on the same socket is the supported path for real servers. Confirm stepping support before considering any sample.

Memory, PCIe and cooling

DDR4 ECC quad channel is the listed memory pattern for test nodes. Even populations protect NUMA fairness. Speed follows DIMM count per board rules. Samples may show different memory behavior than production steppings.

Forty PCIe lanes are the family pattern for E5 v3 parts of this class. Test boards wire lanes per vendor layout. Production slot maps may not apply to sample steppings.

Cooling for 160 W samples needs vendor heatsinks with cool inlets. No retail cooler exists. Samples may run hotter than production equivalents at the same clocks.

Upgrade paths

For production use the Intel Xeon E5-2690 v3 with twelve cores offers retail availability and broad C612 support. The Intel Xeon E5-2680 v3 is a lower power retail twelve core on similar boards. Both need standard platform checks.

Newer server sockets replace Grantley. The E5-2693 v3 remains a sample entry for reference rather than deployment.
