Intel^® 5000X chipset

At the core of Dell Precision 64-bit dual-socket workstations is the Intel 5000x chipset, designed to support the technologies that can open up performance-impacting bottlenecks in primary subsystems. Power users -and the application providers who support them - have access to more bandwidth, more compute power than the previous generation, and to massive memory expansion up to 32GB¹.

Memory

Quad-Channel² DDR2 Full Buffered DIMM Memory
FB-DIMMs are an improved implementation of the current DDR2 standard for memory. With FB-DIMMs, you get the high-speed DDR2 internal architecture with a new, and more reliable, bidirectional serial bus which passes sequentially through every module.The Benefits:

Up to 5X more memory bandwidth with quad-channel² memory over the previous generation platform

Memory scalability up to 32GB¹ with new DDR2 fully-buffered ECC DIMMs

Up to 32GB¹ quad-channel² DDR2 Fully-Buffered DIMM 533MHz ECC memory

(512MB, 1GB, 2GB or 4GB DIMMS; 512MB DIMM not available on the 1KW chassis)

Up to 8 DIMM slots

Hard Drives

Serial Attached SCSI (SAS)

The latest generation of storage technology is SAS (Serial Attached SCSI), which delivers up to 50% higher performance than SATA 10K.

The Dell Precision 490 supports up to three hard drives for a potential capacity of 1.5TB⁴. And with RAID 0, 1 and 5 options, you can configure your storage to meet your needs, whether it's for storing extremely large files, backing them up, or helping to improve performance with data-striping.

SATA 3.0Gb/s 7200RPM with 16MB DataBurst Cache^TM up to 500GB⁴

SATA 3.0Gb/s 7200RPM with 8MB DataBurst Cache^TM up to 250GB⁴

SATA 10K RPM with 16MB DataBurst Cache^TM up to 160GB⁴

SAS 10K RPM up to 300GB; SAS 15K RPM up to 146GB⁴
