HP-Compatible 4GB DDR3 Module

This 4GB DDR3 module is a direct replacement for HP part numbers 655410-D88, 717046-001 and 688600-001. It operates at 1600MHz with a CL11 latency and standard 1.5V voltage. The unbuffered, non-ECC DIMM uses a 240-pin interface and a 2Rx8 chip organisation. It is built for desktop systems that require these exact HP specifications.

Suitable for HP Desktop Upgrades

This module suits owners of compatible HP desktops needing a 4GB DDR3 upgrade to match the original factory specification. Systems that require ECC memory, registered DIMMs, a different voltage, or a higher density per slot should look at alternative modules. Compatibility depends on the motherboard accepting 2Rx8 unbuffered DDR3 at 1.5V.

2Rx8 Organisation Decides Fit

The 2Rx8 chip organisation is the critical specification that determines whether this module will work in a given HP desktop. Some HP platforms only accept 1Rx8 or 1Rx16 configurations and will not post with a 2Rx8 stick. Verify the original module label or the system service manual for the rank and organisation details before purchasing.

Questions about this item

What does the DDR3 1600 PC3-12800 rating mean for real-world throughput?

The module runs at 1600 MHz with a peak transfer rate of 12800 MB/s; actual bandwidth depends on the motherboard's memory controller and whether it operates in single- or dual-channel mode.

Will this 240-pin DIMM fit the memory slots on my HP desktop?

The stick uses the standard 240-pin DDR3 DIMM form factor, so it fits any desktop board that accepts unbuffered non-ECC DDR3 DIMMs; verify your model's maximum capacity per slot before installing.

How do I install the module and what is the common mistake to avoid?

Power off the PC, open the case, align the notch on the 240-pin edge connector with the slot key, press firmly until both retention clips click, then power on; the frequent error is stopping before the clips latch, leaving the module partially seated.
