Dell DDR2 ECC module for legacy servers

This is a 2 GB DDR2 ECC SODIMM operating at 533 MHz with a PC2-4200E rating. It uses a 2Rx8 organisation and gold contacts. The module is a working pull from a tested system and carries the part number HYS72T256020HU-3.7-A.

Suits maintainers of listed Dell PowerEdge

It fits the PowerEdge M600, 1950, 2950, 1900, 1955, R900, 2900 and SC1430 plus Precision 490, R5400, T5400, 690 and T7400. Buyers who need larger capacities, non-ECC memory or a different form factor cannot use this stick.

Single specification that decides fit: ECC DDR2

Only systems that explicitly support ECC DDR2 at 533 MHz in a 2Rx8 SODIMM will accept this module. Check the platform documentation for that exact combination before ordering.

Questions about this item

Does the HYS72T256020HU-3.7-A module ship with any brackets or screws, or is it just the stick?

The listing describes a single 2GB DDR2 533Mhz PC2-4200E ECC memory stick with gold leads. No brackets, screws or additional accessories are mentioned.

Should I choose the ECC registered version or a non-ECC alternative for a Precision T7400?

The module is DDR2 533Mhz PC2-4200E ECC registered memory. Precision Workstation T7400 is listed as a compatible system, so this ECC registered stick is the correct type for that workstation.

Will the 533Mhz PC2-4200E rating run at full speed in a PowerEdge 2950 server?

The stick is rated PC2-4200E at 533Mhz. PowerEdge 2950 appears in the compatible systems list, so the module will operate at its rated speed in that server.
