Intel Xeon W-2145 socket: LGA 2066

What the Xeon W-2145 is

The Xeon W-2145 is an eight core, sixteen thread workstation processor from Skylake-W. It launched in August 2017 with a 3.7 GHz base and up to 4.5 GHz Turbo at 140 W. Eight cores at very high clocks cover workstations where both interaction and rendering matter.

Eleven megabytes of L3 cache feed eight cores. The 3.7 GHz base leads workstation parts for responsive work, while 4.5 GHz boost leads peaks. One hundred forty watts need robust tower cooling.

No integrated graphics are present. Quad channel DDR4-2666 ECC suits large projects with error cover. Forty eight PCIe lanes allow professional GPUs.

Intel aimed the W-2145 at high clock workstations above the W-2133. Creators who model and render on one tower benefit most. Locked multiplier keeps fleets stable.

Socket and motherboard compatibility

The W-2145 fits LGA 2066 on C422 with ECC. X299 boards lack workstation features. Check the board CPU list.

Four channels and 48 lanes suit single socket towers with strong GPUs. The Socket vs chipset: what decides whether a CPU works guide explains C422 use.

The Xeon W-2135 is the six core clock sibling on the same socket. The W-2155 adds two cores where threads help.

Memory, PCIe and cooling

DDR4-2666 ECC in four channels up to 512 GB is the target. Quad channel kits hold bandwidth for large assemblies. ECC protects long jobs.

Forty eight PCIe lanes feed GPUs and NVMe scratch. Towers balance graphics and storage per manuals.

One hundred forty watts cool with workstation air or liquid. High clocks need steady airflow.

Upgrade paths

On C422 the step is W-2155 for more cores, reusing board and DDR4.

Past LGA 2066 a new platform is required.
