24-Core Xeon Gold 5318Y Server CPU

The Intel Xeon Gold 5318Y is a 24-core server processor built on 10 nm Ice Lake architecture. It operates at a 2.1 GHz base frequency with a 3.40 GHz maximum turbo frequency. The chip provides 48 threads through Hyper-Threading support and includes 36MB of L3 cache. It fits the LGA 4189 socket and has a 165W thermal design power.

Suits dense virtualisation

The eight-channel DDR4 2933 memory controller and 64 PCI Express 4.0 lanes support large memory footprints and extensive I/O connectivity. Virtualization technology is included for hypervisor deployments. Buyers who need integrated graphics or single-thread frequencies above 3.40 GHz should consider a different processor class.

LGA 4189 socket compatibility decides fit

This processor only installs in motherboards equipped with an LGA 4189 socket. The 165W thermal design power requires a cooling solution rated for that heat output. Verify the platform supports 10 nm Ice Lake Xeon processors before purchase.

Questions about this item

What memory speed and channel count does the Xeon Gold 5318Y support?

The integrated controller runs DDR4 at 2933 MT/s across eight channels, providing the maximum supported bandwidth for this processor.

What socket and thermal design power does the CD8068904656703 require?

It fits an LGA 4189 socket and has a 165 W TDP, so the cooler and motherboard power delivery must be rated for that heat load.

How is the processor installed in the LGA 4189 socket, and what step is often missed?

Align the notches, place the CPU gently, close the carrier and torque the four captive screws in a cross pattern; skipping the cross-pattern tightening is the common mistake.
