Specifications

The following figure shows the typical system board block diagram.

NOTE: The x1, x4, 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.
Processor technology
This computer uses the Intel® 3450 chipset, including support of the Quad Core Intel® Xeon™
processor W3450 Series and processors of up to 95W. These processors incorporate an integrated 2-
channel memory controller, microarchitecture improvements, and L3 caching to improve performance.
In addition, the computer uses the Intel DMI interface to connect the processor and I/O controller.
Memory technology
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)
are supported.
NOTE: To optimize performance, distribute the DIMMs across both memory channels. See Memory
on page 92 for more information.
Graphics
The computer supports PCIe Gen2 graphics cards in one PCIe2 x16 slot. The system supports multiple
graphics cards as long as the total power usage of all cards fits within the total PCI power budget of
100W.
