Dell PowerEdge and Precision Memory Kit

This 4GB kit contains two 2GB modules of 240-pin DDR2 SDRAM rated at 533 MHz (PC2-4200). It is built for Dell PowerEdge 1950, 2900 and 2950 servers plus Precision Workstation 490 and 690 desktops. The matched pair installs directly into supported systems to restore or expand memory capacity.

Suited for Dell Server and Workstation Owners

Administrators maintaining the listed Dell PowerEdge or Precision models can use this kit to replace failed modules or populate empty slots. Builders working on platforms that require a different pin count, voltage or DDR generation should select memory qualified for those specific systems instead.

240-Pin DDR2 533 Form Factor

The 240-pin DDR2 interface at 533 MHz is the single specification that determines fit and function. Only systems designed for this exact module type will recognise and operate the kit correctly.

Questions about this item

Will the 240-pin DDR2 modules fit the DIMM slots on my Dell PowerEdge 2950?

Yes — the kit is built as 240-pin DDR2 SDRAM at 533 MHz (PC2 4200) and matches the memory specification for the PowerEdge 2950.

What is the correct way to seat both 2 GB sticks so the server recognises the full 4 GB?

Insert each module into the paired slots for a single channel, press down evenly until the retention clips click, then power on and verify 4 GB in the BIOS.

If a module fails years from now, can I replace just one 2 GB stick or must I swap the pair?

Each stick is a standalone 2 GB DDR2 533 module, so a single failed unit can be replaced with another DDR2 533 240-pin 2 GB DIMM.
