What the Xeon E5-2669 v3 is
The Xeon E5-2669 v3 is a 12 core Haswell-EP OEM part on LGA 2011-v3 for dual socket cloud nodes. It runs 12 cores and 24 threads at 2.3 GHz base with turbo to 3.1 GHz. Thirty megabytes of Smart Cache cover guests. Power is 120 W on 22 nm with 2015 availability. The SKU shipped through system vendors rather than boxed retail.
Twelve cores balance density and clocks for virtualization hosts. Turbo to 3.1 GHz helps single thread tasks while all core work settles lower. Two QPI links tie dual sockets. The OEM path means firmware support lives with the vendor image.
No integrated graphics exist. DDR4 with ECC over four channels feeds the node. Buyers meet it inside refurbished cloud servers where 12 threaded cores at 120 W fit power budgets.
Socket and motherboard compatibility
The 2669 v3 fits LGA 2011-v3 on C612 Grantley dual socket boards. Vendor BIOS must carry the OEM microcode. The socket also hosts HEDT parts, but server ECC boards differ from X99 desktop boards. Check the vendor support list for the exact node.
DDR4 RDIMMs with ECC are the standard population. The Socket vs chipset: what decides whether a CPU works guide covers concepts, vendor docs decide DIMM order. LGA 2011 without v3 never boots Haswell-EP.
Memory, PCIe and cooling
DDR4 ECC over four channels to 768 GB per socket suits cloud hosts. Registered modules allow dense memory. Speeds reach 2133 MHz on 12 core configs. Populate evenly for bandwidth.
PCIe 3.0 with 40 lanes per socket serves NVMe and networking in x4, x8 and x16 splits. Cloud nodes often prioritize network throughput. NUMA placement affects tail latency.
Cooling uses 120 W server heatsinks with front to back airflow. No boxed cooler exists. Refurbished nodes need fresh paste and clean fans to hold turbo.
Upgrade paths
On the same socket the Intel Xeon E5-2676 v3 runs 2.4 GHz to 3.0 GHz nearby for similar density, while the Intel Xeon E5-2678 v3 lifts to 2.5 GHz to 3.3 GHz for higher clocks. All share LGA 2011-v3 where firmware lists them.
A move to v4 needs Broadwell-EP BIOS. The 2669 v3 covers OEM 12 core Haswell-EP where vendor nodes decide availability.
