Server processor for dual-socket platforms

The Intel Xeon Gold 5520+ is a 28-core server processor built for LGA 4677 platforms. It delivers a 2.2 GHz base frequency and a 4.0 GHz maximum turbo frequency across 56 threads. The part includes 52.5 MB of L3 cache and supports DDR5 memory at 4800 MHz over eight channels.

Suited to dual-socket enterprise workloads

This processor targets dual-socket servers that need 28 cores and 80 lanes of PCI Express 5.0 connectivity. It is not intended for single-socket workstations or builds that require lower thermal output than the 205 W design power. Buyers needing more than 4 TB of memory per socket should evaluate other options.

LGA 4677 socket and 205 W TDP define compatibility

The CPU fits only LGA 4677 server boards designed for a 205 W thermal envelope. It provides 80 PCIe 5.0 lanes and eight DDR5 channels with a 4 TB maximum memory capacity. Systems without the matching socket and power delivery cannot use this part.

Questions about this item

Does the LGA 4677 socket and 205 W TDP require a specific server chassis and cooler?

This processor uses the LGA 4677 socket and has a 205 W thermal design power. You need a server motherboard with that socket and a cooler rated for at least 205 W, plus a chassis with adequate airflow for sustained loads.

What is the correct installation procedure for the LGA 4677 package, and which step is most often missed?

Align the notches on the processor with the socket keys, place it gently without pressure, and close the load plate. The step most often missed is torquing the retention screws in the specified diagonal sequence to ensure even contact pressure.

When should the thermal interface material be replaced on this 28-core processor?

Replace the thermal interface material whenever the cooler is removed or reseated. For continuous 205 W operation in a server environment, inspect and consider refreshing the paste every one to two years to maintain optimal heat transfer.
