System-Specific DDR2 667 Kit

This Kingston 8 GB kit contains two 4 GB 240-pin DDR2 SDRAM modules rated at DDR2 667 (PC2 5300) and 1.80 V. It is built as a dual-channel kit validated for HP/Compaq systems using part numbers 408854-B21 or EV284AA.

Suitable for HP/Compaq DDR2 upgrades

The dual-rank modules suit owners of compatible HP/Compaq workstations or desktops that require DDR2 667 memory in matched pairs. Buyers whose systems demand a different DDR2 speed, a different voltage, registered ECC modules or a higher total capacity should look elsewhere.

DDR2 667 (PC2 5300) speed grade

The modules operate at the DDR2 667 (PC2 5300) data rate with 1.80 V supply voltage. Confirming that the target platform specifies this exact speed grade and voltage is the single check that decides whether the kit will function correctly.

Questions about this item

What does the PC2 5300 rating mean for real-world bandwidth?

PC2 5300 indicates a peak transfer rate of 5300 MB/s per module.

Will the 240-pin DDR2 DIMMs fit my HP/Compaq workstation?

These 240-pin DDR2 DIMMs are built for HP/Compaq systems that accept DDR2 667 memory.

How do I install the two 4GB modules for dual-channel operation?

Insert both modules into matching-coloured DIMM slots — usually slots 1 and 3 — so the memory controller can run in dual-channel mode.
