SKU CH-FZZ4-T3V4P MPN PK8071305129200

Six-core workstation processor with 12 threads, 2.1 GHz base clock and DDR5-4800 memory support

  • Supported memory speedDDR5 4800
  • 6 cores and 12 threads handle parallel workloads
  • 1 GHz base clock with 4.2 GHz turbo adapts to burst demands
  • 15 MB Smart Cache reduces latency for frequent data
  • DDR5 4800 memory controller supports high-throughput workstation tasks
  • FCLGA4677 socket fits compatible server and workstation platforms

Workstation Xeon 6-Core Tray Processor

The Intel Xeon W3-2423 is a six-core, twelve-thread server CPU built on Intel 7 lithography for professional workstations. It operates at a 2.1 GHz base clock and reaches 4.2 GHz max turbo frequency. The processor includes 15 MB of Smart Cache and supports DDR5 4800 memory across four channels.

Suits Multi-Threaded Workloads, Not High Core Counts

This CPU fits workstations running multi-threaded applications such as rendering, simulation or code compilation that benefit from twelve threads and large memory capacity. Builders needing higher core density or higher base frequencies for specialised compute clusters should evaluate other processor options.

FCLGA4677 Socket and DDR5 4800 Support

The processor installs exclusively into an FCLGA4677 socket and requires a compatible workstation chipset. It controls DDR5 memory at 4800 MT/s with a maximum addressable capacity of 2 TB across four channels. Verify motherboard qualification before purchase.

Questions about this item

What memory speed does the FCLGA4677 interface cap at with this Xeon W3-2423?

The integrated controller runs DDR5 at 4800 MT/s, so that is the practical ceiling for memory speed on this socket.

What socket and clearance does the W3-2423 need to fit?

It requires an FCLGA4677 socket; the tray package has no bundled cooler, so you must provide a workstation-grade heatsink that clears the 4677 mounting pattern.

How is the W3-2423 installed, and which step is often missed?

Seat the processor in the FCLGA4677 socket, close the load plate, then apply thermal paste and mount the cooler — skipping the paste or using a cooler not rated for the 4677 pattern causes overheating.
