What the Xeon Silver 4310 is
The Xeon Silver 4310 is a 12-core server processor that Intel released in April 2021 with the Ice Lake-SP range for 2-socket systems. Its Sunny Cove cores run 2.1 GHz base to 3.3 GHz turbo with Hyper-Threading for 24 threads. Cache is 18 MB with 1.25 MB of L2 per core.
The chip balances 12 cores with a modest 120 W envelope for dense scale out nodes. The lower 2.1 GHz base keeps heat in check while turbo still reaches 3.3 GHz for short tasks. The 10 nm process pairs 8 channels of DDR4 with 64 PCIe 4.0 lanes for fast storage and network cards.
There is no integrated graphics on this model, so setup relies on board BMC graphics. ECC memory support guards data across long uptime. The socket package is FCLGA4189 at 77.5 × 56.5 mm.
Socket and motherboard compatibility
The 4310 fits the LGA 4189 socket on Whitley boards for Ice Lake-SP. Cedar Island boards for Cooper Lake share the socket name but do not accept this chip, so the board generation must match the processor generation. The server vendor CPU support list names the exact boards for Silver parts.
Two-socket operation is the design point for Xeon Silver parts, with single socket boards possible where the vendor qualifies them. A buyer building dense 2-socket nodes should confirm per-socket licensing before choosing 12 cores over 10 or 16.
Check memory population rules for 2-socket boards when ordering. Sixteen DIMM slots per socket is the platform shape, and both sockets should match in capacity and speed.
Memory, PCIe and cooling
The memory controller supports DDR4 up to 2666 MT/s in 8 channels, up to 6 TB per socket, with ECC support. Scale out nodes use RDIMM pairs across all channels for bandwidth with integrity. Optane persistent memory is a board option on qualifying platforms.
The CPU supplies 64 PCIe 4.0 lanes per socket for network cards and NVMe storage. Two-socket boards split lanes across slots and onboard controllers, so the board specifications state which slots reach full speed. Two UPI links at 10.4 GT/s carry socket to socket traffic.
At 120 W, vendor-qualified air heatsinks with strong directed chassis airflow suffice. Mounting is board specific with no retail pattern, and the CPU cooler compatibility by socket guide explains why server sockets list no desktop bracket.
Upgrade paths
Against the Intel Xeon Silver 4310T, the 4310 trades thermal tolerance for higher clocks in a similar envelope. The T part suits warm edge sites, while this standard part suits cool data halls with more speed. Both share Whitley boards and DDR4-2666 limits.
Moving to LGA 4677 needs new boards and DDR5 memory for Sapphire Rapids generations. The 4310 fits a scale out web tier, a dense virtual host, or a storage controller with light compute.
For used buyers, the 12-core Silver makes sense when thread density beats single thread speed. When clocks matter most, the 8-core 4309Y holds higher bases on the same board.
