Intel Xeon E5-2618L v3 socket: LGA 2011-v3

What the Xeon E5-2618L v3 is

The Xeon E5-2618L v3 is a low voltage Haswell-EP eight core for efficient dual socket servers on LGA 2011-v3. Intel set eight cores and 16 threads at 2.3 GHz base with turbo to 3.4 GHz. Twenty megabytes of Smart Cache cover guests per watt. Power is 75 W on 22 nm from September 2014. Wide turbo range keeps single thread bursts near standard parts while base power stays low.

Low base clocks sip power across eight cores in dense racks. Turbo to 3.4 GHz preserves response for control tasks. Sixteen threads consolidate services with ECC memory. Cache size matches the 85 W 2630 v3 for similar guest density. An SSD fabric shapes throughput at this power. Buyers pick the L where 85 W parts would exceed rack budgets but eight threads are still needed.

No integrated graphics exist. DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for dense operators who buy threads per watt at 75 W.

Socket and motherboard compatibility

The E5-2618L v3 fits LGA 2011-v3 on C612 Grantley boards with low power support. Vendor tables list L parts with 75 W guidance. Check the minimum BIOS with v3 microcode. X99 desktop boards never suit low voltage server chips.

ECC RDIMMs over four channels carry memory. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so use server population rules. Cooling uses vendor 75 W heatsinks with rack airflow.

A standard 85 W eight core on the same socket adds base clocks where power allows. Confirm cooling before swapping L for standard parts.

Memory, PCIe and cooling

DDR4 ECC quad channel per socket suits efficient guests. Even DIMM maps protect NUMA fairness. Large RDIMMs reach high counts. Speed steps with population per manual.

Forty PCIe lanes per socket feed NICs and HBAs for scale out nodes. Dual socket I/O should respect NUMA locality. Vendor slot maps guide controller choices.

Vendor 75 W cooling sustains loads quietly with cool inlets. No retail cooler exists. Turbo to 3.4 GHz needs per core headroom.

Upgrade paths

Within the socket the Intel Xeon E5-2630 v3 at 2.4 GHz to 3.2 GHz is a higher base 85 W step on similar boards. The Intel Xeon E5-2630L v3 at 1.8 GHz to 2.9 GHz is a lower power 55 W sibling where watts matter most. Both share C612 mounting.

Newer efficient sockets replace Grantley. The E5-2618L v3 covers dense hosts where eight cores at 75 W are required.
