About this part
Refurbished Intel Xeon Platinum 8256, a 4-core, 8-thread processor for LGA 3647 two-socket and four-socket servers. The Xeon Platinum 8200 series is the top bin of Intel's 2nd Gen Xeon Scalable (Cascade Lake-SP) family: up to 28 cores, six DDR4-2933 channels at one DIMM per channel, 48 PCIe 3.0 lanes and Optane persistent memory support. It scales past two sockets for the largest hosts.

Compatibility
This Cascade Lake-SP part fits LGA 3647 boards only, not LGA 4189 servers. A 1st Gen Xeon Scalable server needs a Cascade Lake capable BIOS first (2.1.x or newer on Dell 14th gen), flashed with the old CPUs installed; do not mix generations. The HPE ProLiant DL560 Gen10 needs mezzanine kit P07991-B21 for sockets three and four. In a two-socket build, run a matched pair: the same SKU in both sockets; a four-socket build needs four matching CPUs. Browse matching parts for the Dell PowerEdge R940.
When to Choose This
The Platinum 8256 is a four-core licensing part with Platinum scaling: a 3.8 GHz base, DDR4-2933 and support for up to eight sockets. It suits four-socket servers running software licensed per core, where memory footprint matters more than threads. The Gold 5222 gives the same four cores and clocks for two- and four-socket builds at lower cost. Trap: four cores per socket is weak for anything else.
