Four green FB-DIMM DDR2 modules with gold contacts

SAMSUNG

SAMSUNG 8GB (4x2GB) FB-DIMM DDR2 PC2-5300 667MHz ECC memory upgrade

SKU CH-XFFG-PHBWW

8GB fully buffered DDR2 ECC kit with four 2GB modules running at 667MHz for Dell Precision 690 workstations

  • Capacity8GB (4 x 2GB)
  • 8GB total capacity for demanding workloads
  • Fully buffered DDR2 architecture improves signal integrity
  • ECC protection detects and corrects data errors
  • 667MHz PC2-5300 speed matches system requirements
  • 240-pin FB-DIMM form factor fits Precision 690

Compatible Dell Precision 690 upgrade

This 8 GB kit contains four 2 GB FB-DIMM modules built for the Dell Precision Workstation 690. Each stick runs at 667 MHz on the PC2-5300 standard and includes ECC error correction. The fully buffered design matches the workstation's memory architecture.

Suited for 690 owners needing ECC capacity

Buyers restoring or expanding a Precision 690 can install this kit directly into the 240-pin slots. Systems that require unbuffered or standard registered DDR2 cannot use these fully buffered modules. Shoppers after higher densities or different form factors should consider other options.

FB-DIMM DDR2 PC2-5300 667 MHz interface

The modules operate at 1.8 V with a 256Mx72 organisation across four banks. Refresh timing is specified at 7.8 µs for 8K cycles. Only platforms designed for FB-DIMM DDR2 at this speed will recognise and run the kit correctly.

Questions about this item

How much heat and power does the 667MHz FB-DIMM draw when the workstation runs continuously?

Each 2GB module operates at 1.8V SSTL signalling; four modules scale the total power draw proportionally, and the fully buffered architecture adds the AMB chip heat that a workstation chassis is designed to dissipate.

What must the system already provide for these 240-pin FB-DIMMs to function?

A Dell Precision 690 or compatible platform with an FB-DIMM memory controller, four available 240-pin DDR2 slots, and ECC support in the chipset and BIOS.

Will the PC2-5300 667MHz speed work alongside slower DDR2 modules I might keep installed?

The memory controller will clock all populated channels down to the slowest module's rated speed, so mixing with slower DDR2 FB-DIMMs forces the 667MHz kit to run at that lower rate.
