Processor technology
This workstation uses the Intel® X58 Express chipset to support the latest Quad Core Intel® Xeon™
processor W3500 Series, including processors up to 130W. These processors incorporate an integrated
3-channel memory controller, microarchitecture improvements and large L3 cache to provide superior
performance. In addition, the workstation uses Intel QuickPath Interconnect (QPI) to connect the
processor and I/O controller with speeds up to 6.4 GT/s.
Memory technology
The workstation dual in-line memory modules (DIMMs) are based on DDR3 1333MHz technology, and
are error checking and correcting (ECC)-protected. Three direct attach memory channels permit low
latency accesses and fast data transfer for improved performance. The workstation supports system
memory sizes of up to 16GB (in the 4-DIMM Z400s, using 4-GB DIMMs) and 24 GB (in the 6-DIMM
Z400s, using 4-GB DIMMs).
NOTE:
DIMMs should be distributed across all three memory channels for optimal performance.
Graphics
The workstation supports PCIe Gen2 (PCIe2) bus speeds and can support dual PCIe Gen2 graphics
cards in PCIe2 x16 slots. It supports graphics cards up to 150W in the primary graphics slot. If the
primary graphics card consumes less than 150W, a second graphics card may be supported in the
second PCIe2 x16 slot, subject to the overall 150W power system limitations.
Expansion card slots
The workstation implements one Intel X58 I/O chip to provide a total of six high-performance graphics
and I/O slots. In addition to the two full x16 PCIe Gen2 slots, two additional PCIe x8 (4) slots (x8
