The Supermicro SYS-2027R-72RFTP+ contains a two-socket (LGA 2011) motherboard built for Intel's Xeon E5-2600 and E52600 v2-series processors. The tested system had two Xeon E52690 v2 10-core CPUs running at 3.0GHz. It arrived preconfigured with 64-bit Windows Server 2008 R2 running on 64 GB of 1,866MHz ECC DDR3 memory, a mere fraction of its 1.5-TB LRDIMM maximum. The system's 24 240-pin DIMM slots also support as much as 768 GB of RDIMM or 192 GB of UDIMM. Incidentally, both CPUs must be present for access to some motherboard features, such as PCIe slots and controllers.
