HP 512MB DDR2 DIMM module

This is a single 512MB DDR2 SDRAM DIMM manufactured by HP for desktop systems. It operates at 667MHz and conforms to the PC2-5300 standard with non-ECC error checking. The module uses a 240-pin interface and a 1Rx8 organisation. It suits owners of compatible legacy workstations or servers needing a direct replacement.

Included module and identification

The package contains one memory module labelled with part number 377725-888 and the Samsung die code M378T6553EZS-CE6 0712. No additional brackets, cables or software utilities are supplied. The stickers provide the exact specifications required for verification against the system service manual.

512MB capacity limit

The module provides exactly 512MB of addressable memory. Systems requiring larger individual DIMMs or higher total capacity cannot use this part to meet those requirements. Buyers needing 1GB or more per slot should select a different module.

Questions about this item

Will the 512MB DDR2 module need replacement if I later move to a motherboard that requires 240-pin DDR2 ECC memory?

This stick is non-ECC, so a board that only accepts ECC DIMMs would require a different module.

What limit appears first when the 512MB DDR2-667 DIMM runs at full speed for long periods?

The 512MB capacity is the first bottleneck; sustained workloads will exhaust the address space before the 667MHz data rate saturates.

How much heat and power does the 240-pin DDR2 stick produce when it runs all day?

Standard DDR2 DIMMs of this density draw only a few watts and stay cool enough for passive airflow in a typical chassis.
