About this part
Refurbished Intel Xeon Platinum 8280L, a 28-core, 56-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. The L suffix raises the memory ceiling to 4.5 TB per socket.
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. 205 W is the top power class for this socket: in the 1U Dell PowerEdge R640, check Dell's thermal restriction table; some drive layouts call for high-performance fans. HPE ships CPUs of 130 W or more with the high-performance heatsink on the ProLiant DL360 and DL380 Gen10. 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 R840.
When to Choose This
The 8280L is the 28-core flagship with the large-memory option: a 2.7 GHz base and a 4.0 GHz turbo. It is for in-memory databases and for hosts that pair large DIMMs with Optane persistent memory past 1 TB per socket. If the build stays at or under 1 TB per socket, the plain Platinum 8280 has the same cores, clocks and power for less. Trap: 205 W per socket needs matching heatsinks, fans and power supplies. The Platinum 8276L keeps 28 cores and the 4.5 TB ceiling at 165 W on a 2.2 GHz base.
