Compatible Compaq Presario upgrade

This 4 GB DDR3 module is built for Compaq Presario CQ5700Y, CQ5700F, CQ5806LA and CQ5810 desktops. It targets owners of those systems who need a straightforward capacity increase without guessing compatibility. The 240-pin DIMM fits the two available memory sockets and supports the platform's maximum of 32 GB total expansion.

Single-stick kit with dual-channel note

The package contains one unbuffered non-ECC stick rated at PC3-10600 1333 MHz with CL9 9-9-9 timing at 1.5 V. HP documentation states the memory bus runs at 1066 MHz, so the module will operate at that speed. Modules may be installed one at a time, but like pairs are required to enable dual-channel operation on this platform.

Standard DIMM form factor

The stick uses a plain green PCB without a heat spreader, keeping the profile low for tight chassis clearances. Gold-edge 240-pin connectors ensure reliable seating in the system's DIMM slots. A 64-bit operating system is needed to address more than 4 GB, and installed memory may be recognised as 3.5 GB or less depending on system configuration.

Questions about this item

Will the 240-Pin DDR3 module need any firmware updates or re-timing after years of use?

No firmware or re-timing is required; the module runs at its rated 1333 MHz CL9 1.5 V settings for its service life.

What speed ceiling appears first when the memory runs continuously in the Presario CQ5700Y?

The system memory bus locks to 1066 MHz, so sustained throughput is capped at that rate regardless of the module's 1333 MHz rating.

How much heat or fan noise does the unbuffered 1.5 V DIMM add during all-day operation?

Without a heat spreader the stick runs at standard JEDEC 1.5 V, adding negligible heat and no audible noise to the chassis airflow.
