Each processor has either 15 cores (up to 2.8 GHz), 12 cores (up to 2.6 GHz), 10 cores (up to 2.2 GHz), eight cores (up to 2.0 GHz), or six cores (up to 3.4 GHz). There are three QPI links up to 8.0 GTps each. Up to 1600 MHz memory speed. Up to 37.5 MB L3 cache. Intel C602J chipset.

Memory

4 x 8GB PC3-12800 ECC 1600 MHz LP Registered DIMMs

Up to 96 DIMM sockets (24 DIMMs per processor, installed in the Compute Book). RDIMMs and LRDIMMs (Load Reduced DIMMs) are supported, but memory types cannot be intermixed. Memory speed up to 1600 MHz.

Memory maximums

With RDIMMs: Up to 1.5 TB with 96x 16 GB RDIMMs and four processors.

• One PCIe 3.0 x16 (x8-wired), half length, full height (Primary I/O Book)
• One ML2 slot for network adapter (PCIe 3.0 x8) (Primary I/O Book)
• Two optional I/O Books, each with three slots, all full height (using these I/O Books requires four processors). Optional books are hot-swap capable.

Optional I/O Books can be either of the following options:

• Half-length I/O Book: Two PCIe 3.0 x8 slots, one PCIe 3.0 x16 slot.
• Full-length I/O Book: Two PCIe 3.0 x16, one PCIe 2.0 x4 slot; two aux power connectors: 150 W and 75 W. Supports one double-wide GPU up to 300 W.
