Intel Xeon E5-1630 v4 socket: LGA 2011-v3

What the Xeon E5-1630 v4 is

The Xeon E5-1630 v4 brings Broadwell-EP to LGA 2011-v3 for single socket workstations with DDR4. It launched in June 2016 with a 3.7 GHz base and up to 4.0 GHz boost at 140 W. Intel targets CAD desks that need four fast cores with ECC on one chip.

Ten megabytes of Smart Cache carry models and assemblies. The high base clock keeps interactive work responsive. Eight threads cover design apps plus background renders.

There is no integrated GPU, so a discrete workstation card is required. The process is 14 nm. The multiplier is locked. DDR4-2400 with ECC in four channels feeds cores with up to 1.5 TB on server boards.

Buyers add cooling at purchase because no cooler ships in the box. The 140 W rating needs a tower with steady airflow. Turbo Boost Max 3.0 lifts favored cores for single threads where modeling needs it.

Socket and motherboard compatibility

The Xeon E5-1630 v4 fits LGA 2011-v3 on C612 workstation boards and X99 boards with DDR4 slots. Makers list Broadwell-EP with 2016 BIOS builds. Early stock may need an update before posting.

Single socket builds are the case because this SKU links no QPI for 2S. Dual socket racks need E5-2600 v4 parts instead. The Socket vs chipset: what decides whether a CPU works guide covers board matching.

Tower workstations with one socket are the deployment. Growth means another LGA 2011-v3 chip on the same board where listed. Power supplies need solid rails for 140 W plus graphics.

Memory, PCIe and cooling

DDR4-2400 with ECC in four channels suits workstations with large assemblies. Quad channel bandwidth helps simulation. Start with 32 GB for CAD work.

PCIe 3.0 with 40 lanes from the CPU allows two workstation cards plus NVMe per board layout. Chipset lanes cover extra SATA and USB for arrays.

Cooling follows the 80 by 80 mm LGA 2011 pattern in the CPU cooler compatibility by socket guide. A 140 W tower holds boost during renders. No cooler ships in the box. ECC guards memory against single bit errors.

Upgrade paths

On the same socket, the Intel Xeon E5-1620 v4 trims to 3.5 GHz base for lower cost desks with the same 10 MB cache. The Intel Xeon E5-1650 v4 moves to six cores for heavier multitasking. Both share LGA 2011-v3 boards and DDR4.

HEDT Intel Core i7-6850K gives six fast cores without ECC for gaming rigs. It needs X99 boards and a different use case.

Past workstations move to Skylake-W or Xeon W. The E5-1630 v4 covers 2016 CAD desks where four fast cores with ECC must deploy on Grantley boards.
