What the Xeon E5-1660 v3 is
The Xeon E5-1660 v3 is a Haswell-EP eight core for single socket workstations on LGA 2011-v3. Intel set eight cores and 16 threads at 3.0 GHz base with turbo to 3.5 GHz. Twenty megabytes of Smart Cache serve creation and simulation. Power is 140 W on 22 nm from September 2014. Balanced clocks with eight threads suit interactive desks that also render.
At 3.0 GHz base with bursts to 3.5 GHz, modeling stays direct while all core renders use every thread. 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 engineers who want eight threads without reaching for ten and twelve core premiums.
DDR4 ECC over four channels feeds the socket with DMI to the companion. The mix covers single socket towers where eight fast threads with protection are the brief.
Socket and motherboard compatibility
The E5-1660 v3 fits LGA 2011-v3 on C612 workstation boards for uniprocessor use. Check the vendor BIOS matrix for v3 stepping. Server dual boards accept it but follow different 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 ten core on the same socket adds threads where renders queue. Confirm power before moving between workstation SKUs.
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 population per manual.
Forty PCIe lanes feed professional graphics plus NVMe. Workstation wiring favors x16 graphics with storage beside. Chipset lanes add USB and SATA. Manuals detail U.2 sharing.
Tower 140 W cooling holds 3.0 GHz sustained loads with bursts to 3.5 GHz. Firm pressure on the large package matters. Keep exhausts open during long jobs.
Upgrade paths
On the same socket the Intel Xeon E5-1680 v3 with eight faster threads is a clock step on similar boards. The Intel Xeon E5-1650 v3 with six faster threads trims threads for response focused desks. Both share C612 workstation mounting.
Newer workstation platforms replace Grantley. The E5-1660 v3 covers balanced single socket ECC desks where eight threads at 3.0 GHz are ideal.
