What the Xeon E5-1680 v3 is

The Xeon E5-1680 v3 is a single socket Haswell-EP eight core for workstations on LGA 2011-v3. Intel set eight cores and 16 threads at 3.2 GHz base with turbo to 3.8 GHz. Twenty megabytes of Smart Cache serve creation and simulation. Power is 140 W on 22 nm from September 2014. Uniprocessor design targets desks that need ECC without dual socket cost.

High clocks with eight threads suit interactive creation where response and throughput both matter. At 3.2 GHz base with bursts to 3.8 GHz, modeling steps feel direct while renders use all cores. ECC DDR4 guards long jobs against errors. Discrete professional graphics carry display duties, since no integrated GPU exists. An NVMe array shapes project load times. Buyers pick the 1680 v3 where single socket ECC workstations must stay fast.

DDR4 ECC over four channels feeds the socket. DMI links the CPU to the C612 companion for workstation I/O. The mix is a workstation socket for engineers who want eight fast threads with protection at 140 W.

Socket and motherboard compatibility

The E5-1680 v3 fits LGA 2011-v3 on C612 workstation boards for single socket use. Firmware must list the v3 stepping. Check the vendor matrix for the minimum BIOS. Server dual socket boards accept it but waste dual capability on a workstation chip.

ECC RDIMMs or UDIMMs 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 for maps. Cooling is vendor or tower 140 W units with strong case airflow.

A six core on the same socket trims cost where threads matter less. Confirm memory type support before swapping workstation parts.

Memory, PCIe and cooling

DDR4 ECC quad channel suits creation with large scenes. Thirty two to 64 gigabytes cover projects with fast storage. Matched sticks unlock bandwidth. Speed follows DIMM count per manual.

Forty PCIe 3.0 lanes feed professional graphics plus NVMe for project files. Workstation layouts wire x16 to graphics with remaining lanes for storage. Chipset lanes add USB and SATA. Manuals show sharing with U.2 ports.

Large tower cooling holds 3.2 GHz sustained loads with bursts to 3.8 GHz. The FCLGA2011-3 package needs a 140 W rated mount with firm pressure. Keep memory airflow in mind during long renders.

Upgrade paths

Within the socket the Intel Xeon E5-1650 v3 with six cores at 3.5 GHz to 3.8 GHz trims threads for lower cost on similar boards. The Intel Core i7-5960X with eight cores is an HEDT alternative without ECC for single socket creation. Both need platform checks.

Newer workstation sockets replace Grantley. The E5-1680 v3 covers single socket ECC desks where eight fast cores are wanted.
