788321-B21 HPE DL580 Gen9 Xeon E7-8870v3 18-Core Processor

Each HPE CPU kit of this type carries a single Intel Xeon E7-8870v3 for the DL580 Gen9, with 18 cores at 2.1GHz, 45MB of L3 cache, 140W and a 9.6GT/s QPI link.

Two 18-core neighbours bracket it in clock speed: one at 2.0GHz and 115W below, one at 2.3GHz and 150W above. The 140W rating matches two other E7 v3 processors, a 16-core model at 2.2GHz with 40MB of cache and the 4-core 3.2GHz model. It has more cores than either of them and a lower clock than both.

In a DL580 Gen9 the processor count runs from two to four, with one memory cartridge per processor and no fewer than two DIMMs in each cartridge. Four of them add up to 72 cores.

Its replacement processor is spare 802280-001 and the heat sink spare is 735514-001. The memory clock is 1866 with this processor, and different processor models cannot be combined in one server.
