Silver 4310 12-core server processor

The Intel Xeon Silver 4310 is a 12-core, 24-thread CPU built for dual-socket LGA 4189 platforms. It runs at a 2.1 GHz base clock with a 3.30 GHz maximum turbo frequency and carries an 18 MB L3 cache. The 10 nm Ice Lake core supports DDR4-2666 across eight memory channels and provides 64 lanes of PCI Express 4.0 connectivity.

Upgrade from older Silver or Bronze SKUs

Moving to this processor adds two extra cores, higher turbo headroom and PCIe 4.0 lanes compared with previous-generation Silver models limited to PCIe 3.0. The eight-channel memory controller also doubles the theoretical bandwidth available to each socket. The jump is worthwhile when workloads need more parallel threads or faster I/O for storage and accelerators.

Suits virtualisation hosts and database nodes

This chip fits environments that licence by socket and benefit from 24 threads within a 120 W envelope. Buyers who need higher single-thread speeds, larger cache per core or support for newer memory standards should evaluate other processor lines. Systems limited to single-socket boards or older chipsets cannot use the LGA 4189 package.

Questions about this item

What socket and power budget must the motherboard provide for the Xeon Silver 4310?

The processor fits an LGA 4189 socket and has a 120W thermal design power, so the board must support that socket and supply adequate cooling for 120W.

How is the CPU seated in the LGA 4189 socket, and what step is often missed?

Align the triangle marker on the processor with the socket corner, lower it straight down without forcing, then close the independent loading mechanism — the separate retention lever is the step installers sometimes forget to latch fully.

When will the DDR4 2666 memory modules paired with this 8-channel controller need replacement?

DDR4 2666 DIMMs typically last the server's lifetime; replace them only if ECC logs report uncorrectable errors or capacity becomes insufficient for the workload.
