What the Xeon E5-2622 v3 is
The Xeon E5-2622 v3 is an OEM Haswell-EP eight core for vendor servers on LGA 2011-v3. Intel set eight cores and 16 threads at 2.4 GHz base with turbo to 3.4 GHz. Twenty megabytes of Smart Cache serve guests and services. Power is 85 W on 22 nm from September 2014. Wide turbo range keeps single thread bursts near retail parts while base power stays modest.
Eight cores consolidate virtual machines per socket for vendor deployments. Turbo to 3.4 GHz covers control tasks with bursts. Large cache trims memory waits. ECC DDR4 guards data. No integrated graphics exist. OEM validation ties stepping to vendor matrices, so generic board support varies. Used buyers meet this SKU in system pulls.
DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for vendor hosts where eight OEM threads at 85 W are the design point.
Socket and motherboard compatibility
The E5-2622 v3 fits LGA 2011-v3 on vendor C612 Grantley systems. OEM stepping may fail on generic boards. Confirm the matrix before sourcing used parts. X99 desktop never accepts this server OEM chip.
ECC RDIMMs over four channels carry memory. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so follow vendor rules. Cooling is vendor 85 W heatsinks with rack airflow.
Retail eight core E5 v3 offer wider support where OEM locks bind. Check microcode first.
Memory, PCIe and cooling
DDR4 ECC quad channel per socket suits virtual guests. Even maps protect NUMA fairness. Large RDIMMs reach high counts. Speed follows population per manual.
Forty PCIe lanes per socket feed NICs and NVMe for fabric. NUMA placement across QPI links matters. Vendor manuals detail slots.
Vendor 85 W cooling sustains loads with cool inlets. No retail cooler exists. Turbo to 3.4 GHz needs per core headroom.
Upgrade paths
On the same socket the Intel Xeon E5-2630 v3 with eight cores offers retail availability for broader boards. The Intel Xeon E5-2620 v3 with six cores is a lower density retail step. Both need platform checks.
Newer sockets replace Grantley. The E5-2622 v3 covers OEM hosts where eight cores at 85 W are specified.
