The following figure shows the typical system board block diagram.
The x1 and x16 designators describe the mechanical length of the slot. The number in
parentheses lists the number of electrical PCIe lanes routed to the expansion slot. For example, x16(4)
means that the expansion slot is mechanically a x16 length connector, with four PCIe lanes connected.
This computer uses the Intel® Series 3450 chipset, including support of Quad Core Intel Xeon™
processors and processors of up to 95W. These processors incorporate an integrated 2-channel
memory controller, microarchitecture improvements, integrated graphics, and L3 caching to improve
performance. In addition, the computer uses Intel DMI interface to connect the processor to the I/O
The computer dual in-line memory modules (DIMMs) are based on DDR3 1333MHz technology, and
are error checking and correcting (ECC). Two direct-attach memory channels permit low latency access
and fast data transfer to improve performance. System memory sizes up to 16GB (using 4GB DIMMs)
To optimize performance, distribute the DIMMs across both memory channels. See
on page 105
The system supports multiple graphics cards as long as the total power usage of all graphics cards is
less than 45W, and the total of all I/O power usage is less than 80W.
