1GB DDR2 667 PC2-5300 DIMM

This 1GB DDR2 667 PC2-5300 240-pin DIMM is built for HP and Compaq business desktops. It runs at 1.8V with CL5 5-5-5 timing and uses unbuffered, non-ECC chips in a 2Rx8 configuration. The module is designed as a direct drop-in upgrade for the listed workstation models.

Suits owners of HP dc5700, dc7600, dc7700.

Buyers needing ECC error correction or registered buffering should look elsewhere, as this stick provides neither. Systems that require a different pin count, voltage or DDR generation cannot use this module. The single 1GB capacity also limits total memory on boards with few slots.

PC2-5300 667 MHz speed rating

The decisive specification is the PC2-5300 667 MHz rating, which must match the memory controller of the target HP desktop. Installing a module with a different speed grade or latency will prevent the system from booting or force it to run at a lower speed.

Questions about this item

What speed does the DDR2 667 (PC2-5300) interface actually run at in these HP desktops?

The module is rated for DDR2-667 (PC2-5300) at 1.8 V, but several listed systems such as the DC7700P Ultra-Slim and DX2060 only support DDR2-533 MHz, so the memory will downclock to 533 MHz in those models.

Will this 240-pin DIMM fit the small-form-factor and ultra-slim HP chassis listed?

Yes — the stick uses the standard 240-pin DDR2 DIMM form factor, which is the same physical size used across the DC5100 SFF, DC7600 SFF, DC7700 SFF and DC7700 Ultra-Slim desktops.

How do I install the module so the system recognises it in dual-channel mode?

Install the DIMM in the lowest-numbered slot of each memory channel (usually the black slots first); the common mistake is populating only one channel or mixing slots, which forces single-channel operation.
