Xeon W5-2565X 18-core server CPU

The Intel Xeon W5-2565X is an 18-core, 36-thread processor built for single-socket workstations. It runs at a 3.2 GHz base frequency and can reach 4.8 GHz with Intel Turbo Boost Max Technology 3.0. The chip uses the LGA 4677 socket and includes 37.5 MB of L3 cache.

Suited for DDR5 workstations needing 64 PCIe 5.0

This CPU targets professionals who need quad-channel DDR5 4800 support and up to 2 TB of memory capacity. It is not for builders who require multi-socket scalability or a platform that supports registered ECC DIMMs beyond the stated maximum. Buyers needing integrated graphics or a lower thermal envelope should look elsewhere.

240 W base power with 288 W max turbo

The processor has a 240 W TDP and a 288 W maximum turbo power, so the cooling solution must handle sustained loads at that level. No cooler is included in the box. The 10 nm manufacturing process and 64-bit architecture complete the core specification.

Questions about this item

What motherboard socket does the Xeon W5-2565X require?

The processor uses an LGA 4677 socket, so the motherboard must provide that exact socket for installation.

How is the Xeon W5-2565X installed, and what step is often missed?

Seat the CPU into the LGA 4677 socket, close the retention mechanism, then attach a compatible cooler because no cooling device is included in the box.

What memory will the Xeon W5-2565X need later for upgrades or replacement?

It supports DDR5 4800 in quad-channel mode up to 2 TB total capacity across the memory channels.
