Intel Xeon E5-4610 v3 socket: LGA 2011-v3

What the Xeon E5-4610 v3 is

The Xeon E5-4610 v3 is a value 10 core Haswell-EP part on LGA 2011-v3 for 4S scale out servers. Intel set 10 cores and 20 threads at a fixed 1.7 GHz with no turbo. Twenty five megabytes of Smart Cache cover workers. Power is 105 W on 22 nm from the second quarter of 2015.

Fixed low clocks favor dense parallel jobs over latency. Twenty threads per socket add up across four sockets to 80 threads per node. Two QPI links at 6.4 GT/s tie 4S systems. The lack of turbo simplifies power planning in packed racks.

No integrated graphics exist. DDR4 with ECC over four channels feeds scale out guests. Buyers pick the 4610 v3 where socket count with modest clocks beats faster fewer cores on budgets.

Socket and motherboard compatibility

The 4610 v3 fits LGA 2011-v3 on C612 4S Grantley boards. Firmware must list E5-4600 v3 value SKUs. HEDT X99 boards differ in memory support, so use server boards with RDIMMs. Check vendor stepping lists.

Registered ECC DIMMs are required. The Socket vs chipset: what decides whether a CPU works guide covers ideas, vendor docs decide maps. LGA 2011 without v3 never works.

Memory, PCIe and cooling

DDR4 ECC over four channels to 768 GB per socket suits scale out VMs. Value DIMM speeds match the fixed clocks. Even populations protect bandwidth.

PCIe 3.0 with 40 lanes per socket serves networking and storage. Scale out fabrics matter more than accelerators. NUMA balance across four sockets decides throughput.

Cooling uses 105 W server heatsinks with front to back airflow. Fixed clocks ease thermal peaks. Dense rows still need hot aisle management.

Upgrade paths

On the same socket the Intel Xeon E5-4620 v3 adds turbo to 2.6 GHz nearby for bursts, while the Intel Xeon E5-4640 v3 moves to 12 slower cores for denser threads. All share LGA 2011-v3 where listed.

A v4 move needs new firmware. The 4610 v3 covers fixed clock 4S value where predictability matters.
