What the Xeon E5-1620 v3 is
The Xeon E5-1620 v3 is a fast Haswell-EP quad for single socket workstations on LGA 2011-v3. Intel set four cores and eight threads at 3.5 GHz base with turbo to 3.6 GHz. Ten megabytes of Smart Cache serve interactive creation. Power is 140 W on 22 nm from September 2014. High clocks with ECC suit engineers who want response and protection together.
At 3.5 GHz with bursts to 3.6 GHz, modeling steps feel direct while eight threads cover background tasks. ECC DDR4 guards long jobs. Professional graphics handle display, since no integrated GPU exists. NVMe storage shapes project loads. It is a workstation socket for desks where four fast threads beat slower wider server parts for interactive use.
DDR4 ECC over four channels feeds the socket. DMI links the CPU to the C612 companion for workstation I/O. The mix covers single socket towers where speed per core with ECC is the brief.
Socket and motherboard compatibility
The E5-1620 v3 fits LGA 2011-v3 on C612 workstation boards for uniprocessor use. Verify the vendor BIOS matrix for v3 stepping. Server dual boards accept it but follow different memory maps.
ECC UDIMMs or RDIMMs over four channels carry memory per board support. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so use workstation manuals. Cooling is a 140 W tower with strong case airflow.
A six core workstation chip on the same socket adds threads where renders grow. Confirm power before moving between SKUs.
Memory, PCIe and cooling
DDR4 ECC quad channel suits design projects. Thirty two gigabytes covers work with fast storage. Matched sticks unlock bandwidth. Speed follows population per manual.
Forty PCIe lanes feed professional graphics plus NVMe. Layouts favor x16 graphics with storage beside. Chipset lanes add USB and SATA. Manuals detail sharing.
Tower 140 W cooling holds 3.5 GHz sustained loads. Mount pressure on the large package decides thermals. Keep exhausts clear during long jobs.
Upgrade paths
On the same socket the Intel Xeon E5-1630 v3 with four faster threads is a clock step on similar boards. The Intel Xeon E5-1650 v3 with six threads adds width for heavier creation. Both share C612 workstation mounting.
Newer workstation platforms replace Grantley. The E5-1620 v3 covers fast single socket ECC desks where four threads at 3.5 GHz are enough.
