SKU CH-XYK2-7JJGH

Adds 1 GB of DDR2 desktop memory at 800 MHz PC2-6400U in a DIMM module

  • Capacity16GB
  • 1 GB DDR2 capacity upgrades legacy desktops

Dell XG691 DDR2 Memory Module

This Dell XG691 module adds 1GB of DDR2 memory to a desktop PC. It runs at 800MHz under the PC2-6400U standard and uses a standard DIMM form factor. The unit is non-ECC and built with a 2Rx8 rank configuration.

Suitable for owners of legacy desktops needing

This module fits systems that accept PC2-6400U DDR2 DIMMs and have a free slot. It is not for owners of boards that require ECC memory, nor for anyone whose platform only accepts a different memory generation or form factor. Capacity seekers should note the 1GB limit per module.

The PC2-6400U 800MHz DDR2 specification decides fit

Match this exact speed and standard against your motherboard manual before ordering. The 128X64 rank layout and non-ECC design must also align with the board requirements. If the manual lists a different DDR2 speed or requires ECC, this part will not work.

Questions sur cet article

Will the 1 GB DDR2 module run at its rated 800 MHz speed continuously without throttling?

The module is specified for PC2-6400U at 800 MHz. Sustained operation at that data rate is within its rated limits; thermal throttling is not a published constraint for this part.

How much heat and noise does the XG691 add when the system runs all day?

As a passive DDR2 DIMM the module generates only modest heat and no audible noise. Typical case airflow is sufficient for continuous operation.

What existing hardware must I already have for this 128X64 ranked DIMM to function?

A desktop motherboard with DDR2 DIMM slots that accepts PC2-6400U non-ECC memory is required. The board must support 1 GB unbuffered modules.
