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.
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).
DIMMs should be distributed across all three memory channels for optimal performance.
