Xeon W5-2555X 14-core server processor
The Intel Xeon W5-2555X is a 14-core, 28-thread CPU built for single-socket workstations. It runs at a 3.3 GHz base frequency and reaches 4.8 GHz with Intel Turbo Boost Max Technology 3.0. The processor includes 33.75 MB of L3 cache and a quad-channel DDR5 4800 memory controller supporting up to 2 TB of RAM.
Suited for single-socket workstations needing high
This processor fits builders targeting rendering, simulation or virtualization workloads on a single LGA 4677 platform with PCIe 5.0 and 64 lanes. Buyers who need multi-socket scalability or a lower thermal envelope should evaluate other options because this part is rated for 210 W base and 252 W max turbo power with no cooler included.
DDR5 4800 quad-channel memory controller decides
The integrated controller only operates with DDR5 4800 memory in a four-channel topology, so the motherboard and DIMMs must match that exact specification. Systems built around a different memory generation or channel count cannot use this processor.

คำถามเกี่ยวกับสินค้านี้
What motherboard socket and DDR5 speed are required for the Xeon W5-2555X?
The processor fits an LGA 4677 socket and its integrated memory controller runs DDR5 at 4800 MT/s.
Will my existing PCIe 3.0 add-in cards operate with this CPU?
The chip provides 64 lanes of PCIe 5.0, which are backward compatible with PCIe 3.0 devices at their native speeds.
How can I confirm the 14-core, 28-thread processor is running at its rated 3.3 GHz base and 4.8 GHz max turbo?
Monitor core clocks under load with a hardware utility; sustained all-core operation should sit at 3.3 GHz while single-core peaks reach 4.8 GHz.
