44E4488 IBM Microprocessor Board Assembly, System x3850 M2/x3950 M2 (7233/7234)

44E4488 is the microprocessor-board assembly for the IBM System x3850 M2 and System x3950 M2 machine types 7233 and 7234. Machine type 7141 takes a different board, 43W8670; check the machine type before choosing between the two.

IBM's service parts for these servers include the processors that fit the 7233 and 7234 board: a 2.13 GHz quad-core at 50 W, a 2.13 GHz six-core at 65 W, 2.13 GHz quad-cores at 90 W with 8 MB or 12 MB cache, 2.4 GHz quad-core and six-core processors at 90 W, and a 2.67 GHz six-core at 130 W. The server takes up to four microprocessors on a 1066 MHz front-side bus.

The board carries microprocessor sockets 3 and 4, mounted with their release levers on opposite sides and turned 180 degrees from each other. It also holds the VRM connectors for the four sockets, the connectors for the memory cards and the ScaleXpander key that enables multi-node operation. LEDs on the board include the FPGA heartbeat and BMC heartbeat indicators.

Each of the four memory cards has eight DIMM connectors for registered ECC PC2-5300 DDR II memory in 1 GB, 2 GB, 4 GB or 8 GB sizes, up to 256 GB in a single node. If the server reports microprocessor error 00019xxx, the service steps are to reseat the board and the processor, then replace the processor and finally the board, which only a trained service technician replaces.
