What the Xeon E5-2699C v4 is
The Xeon E5-2699C v4 brings Broadwell-EP to LGA 2011-v3 for OEM cloud nodes with DDR4. It launched in 2016 with a 2.2 GHz base and up to 2.4 GHz boost at 145 W. Intel built this custom SKU for large buyers that need 22 cores with steady clocks.
Fifty five megabytes of Smart Cache carry guests and tables. The modest boost ceiling suits efficiency tuned fleets. Forty four threads cover VMs plus agents.
There is no integrated GPU, so serial and network manage the node. The process is 14 nm. The multiplier is locked. DDR4-2400 with ECC in four channels feeds cores on Grantley boards.
Buyers receive the chip through OEM channels rather than boxed retail. The 145 W rating needs 2U airflow. Two QPI links at 9.6 GT/s join paired sockets where nodes run 2S.
Socket and motherboard compatibility
The Xeon E5-2699C v4 fits LGA 2011-v3 on C612 server boards with DDR4 slots. OEMs qualify it on their own platforms with custom BIOS builds. Retail boards may lack the microcode for this custom SKU.
Dual socket builds are supported on Grantley-EP 2S platforms. The C suffix marks a custom OEM part. The Socket vs chipset: what decides whether a CPU works guide covers matching.
Rack nodes in OEM fleets are the deployment. Growth means more LGA 2011-v3 nodes through the same vendor. Check the vendor support list before mixing with retail boards.
Memory, PCIe and cooling
DDR4-2400 with ECC in four channels suits OEM hosts. Quad channel bandwidth helps live migration. Start with 256 GB for dense fleets.
PCIe 3.0 with 40 lanes per CPU serves HBAs and NICs. Boards split lanes between risers and NVMe. Chipset lanes add SATA and USB.
Cooling follows server practice with vendor heatsinks for 145 W classes. No cooler ships in the box. ECC guards memory.
Upgrade paths
On the same socket, the Intel Xeon E5-2699 v4 shares 2.2 GHz base with retail availability and higher boost. The Intel Xeon E5-2699R v4 gives the same 22 cores through embedded channels. Both share LGA 2011-v3 boards.
Twenty core E5-2698 v4 suits narrower hosts where listed. It needs the same boards.
Past OEM fleets move to Skylake-SP through vendors. The E5-2699C v4 covers 2016 clouds where 22 steady cores with ECC must deploy.
