The IBM 47C9552 is the system board for the IBM System x3750 M4, machine types 8752 and 8718. IBM service parts carry a separate board for the GA P7LB variant, part number 00FL809. The two boards are separate entries.
The type 8752 x3750 M4 is a 2U rack server for up to four Intel Xeon E5-4600 v2 processors, each with up to 12 cores and up to 30 MB of L3 cache. Two sockets sit on the system board and two on the processor and memory expansion tray. Memory speed reaches 1866 MHz.
The server has up to 48 DIMM sockets, 24 on the system board and 24 on the expansion tray. Capacity is up to 768 GB with 16 GB RDIMMs or 1.5 TB with 32 GB load-reduced DIMMs. Drive bays are up to 16 2.5-inch hot-swap SAS/SATA bays or up to 32 1.8-inch eXFlash SSD bays, with RAID 0, 1 and 10 on the integrated ServeRAID M5210e.
There are up to eight PCIe 3.0 x8 slots: five on the system board and up to three on an optional riser. A dedicated mezzanine slot takes a 2-port 10 GbE or 4-port 1 GbE adapter, and the rear has two USB 2.0 ports, one video port, one serial port and a systems management port. Cooling is by six N+N redundant hot-swap fans.
