Intel Xeon W — Workstation CPUs with ECC Support
Intel Xeon W is the workstation branch of the Xeon family: single-socket processors with high clocks, full ECC memory support and professional platform features that desktop Core chips lack. PC Server & Parts stocks tested pulls across the W-2100 and W-2200 series (LGA 2066) — including the Intel Xeon W-2102, W-2123, W-2125, W-2133, W-2223 and W-2235 — plus W-3200 series (LGA 3647) parts such as the W-3223, with current-generation Xeon w3/w5/w7/w9 processors rotating through as trade-in stock allows. Every CPU is tested in same-generation hardware before listing; if your exact SKU is missing, email us.
Which Workstations Take Xeon W
- Dell Precision 5820 Tower: W-2100 series out of the box; W-2200 supported on later BIOS revisions.
- HP Z4 G4: W-2100/W-2200 series (Xeon W variant of the board).
- Lenovo ThinkStation P520: W-2100/W-2200 series.
- Apple Mac Pro 2019: W-3200 series on LGA 3647.
- Memory: quad-channel DDR4 ECC — 2666 MT/s (W-2100) or 2933 MT/s (W-2200/W-3200).

Quick Answers: Intel Xeon W
What does Xeon W offer over a Core i7/i9?
ECC memory support (with quad-channel bandwidth and much higher capacity ceilings), more PCIe lanes for GPUs and storage, and vPro/RAS platform features — on the same or better clocks than the desktop parts of their era. For CAD, simulation and content pipelines where a flipped bit or a crashed session costs real money, ECC is the reason these platforms exist.
Which Xeon W series fits my machine?
W-2100 and W-2200 (LGA 2066) go into the Dell Precision 5820 Tower, HP Z4 G4 and Lenovo P520 — W-2200 usually needs a newer BIOS where the machine shipped with W-2100. W-3200 (LGA 3647) belongs to the Mac Pro 2019 and high-end C621 boards. The newer w3/w5/w7/w9-2400/3400 chips use socket LGA 4677 and only fit current-generation workstations.
Are used Xeon W CPUs covered by a warranty?
Loose processors follow our 90-day parts return policy: dead-on-arrival or non-conforming CPUs come back for a full refund, with PCSP covering return shipping on defective items. Every unit is tested in real hardware before it ships.
