System x3950 X6 specifications [18].

ProcessorUp to eight Intel Xeon E7-8800 v2 processors, each in a compute book. Each processor has 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.

MemoryUp to 192 DIMM sockets (24 DIMMs per processor, installed in the compute book). RDIMMs and load-reduced DIMMs are supported, but memory types cannot be intermixed. Memory speed up to 1600 MHz.
