Intel Xeon E5-2623 v3 socket: LGA 2011-v3

What the Xeon E5-2623 v3 is

The Xeon E5-2623 v3 is a frequency tuned Haswell-EP quad for latency sensitive servers on LGA 2011-v3. Intel set four cores and eight threads at 3.0 GHz base with turbo to 3.5 GHz. Ten megabytes of Smart Cache serve per core speed over parallel width. Power is 105 W on 22 nm from September 2014. It trades cores for clocks where single thread pace sets service levels.

High base clocks keep databases and control planes direct with few threads. Turbo to 3.5 GHz covers bursts in transaction steps. Eight threads handle services beside guests with ECC memory. Fewer cores mean lower consolidation, but faster response per request. An SSD and fast fabric matter more than core count in these roles. Buyers pick the 2623 v3 where frequency beats width.

No integrated graphics exist, with BMC for management. DDR4 ECC over four channels feeds the socket. Two QPI links support dual nodes. The mix is a server socket for operators who buy speed per core at 105 W.

Socket and motherboard compatibility

The E5-2623 v3 fits LGA 2011-v3 on C612 Grantley boards for single and dual socket use. Firmware must list the v3 stepping. Check the vendor matrix for the minimum BIOS. X99 desktop boards never take Xeon E5 v3 for server duty despite the shared socket.

ECC RDIMMs over four channels carry memory. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so use server manuals for maps. Cooling is vendor 105 W heatsinks with rack airflow.

A six core on the same socket adds threads where parallel guests grow. Confirm power headroom before swapping frequency tuned quads for wider parts.

Memory, PCIe and cooling

DDR4 ECC quad channel per socket suits fast databases. Balance DIMMs for bandwidth. Registered modules reach large counts. Speed follows population per manual.

Forty PCIe 3.0 lanes per socket feed low latency NICs and NVMe for transaction logs. NUMA placement across QPI links matters in dual nodes. Board manuals detail slot wiring for accelerators.

Vendor 105 W cooling holds 3.0 GHz sustained loads with cool inlets. No retail cooler exists. Turbo residency tracks per core states and inlet air.

Upgrade paths

Within the socket the Intel Xeon E5-2637 v3 at 3.5 GHz to 3.7 GHz is a higher clock quad where single thread rules. The Intel Xeon E5-2640 v3 with eight cores adds threads for mixed loads on similar boards. Both share C612 mounting.

Newer server sockets replace Grantley. The E5-2623 v3 covers frequency tuned hosts where four fast cores are wanted.
