Compaq Presario CQ5300 and CQ5500 upgrade

This 2 GB DDR2 module is built for Compaq Presario CQ5300F, CQ5300Y, CQ5500F and CQ5500Y desktops. It installs in a 240-pin DIMM slot and runs at 800 MHz with CL6 timing. The stick is unbuffered, non-ECC and operates at 1.8 V.

Owners of listed Presario models needing a single

The kit contains one 2 GB rank 2Rx8 module, matching the systems' two-slot layout and 4 GB maximum. Buyers whose motherboard requires registered or ECC memory should look elsewhere. Systems with only one free slot can still use this module, but total capacity will stay at 2 GB.

DDR2 800 PC2 6400 speed rating

The module carries a PC2 6400 (DDR2 800) specification with 6-6-6 latency. If the target computer needs a different DDR2 speed grade or a lower voltage, this part will not be compatible.

Domande su questo articolo

Will the DDR2 800 CL6 timing hold under sustained workloads?

The module is rated CL6 at 800 MHz with 6-6-6 timings and 1.8 V operation, which are the JEDEC limits for this speed grade.

Does the stick run hot or draw extra power in a Compaq Presario all day?

At 1.8 V with no heat spreader and unbuffered DDR2 design, power draw and thermals stay within standard JEDEC limits for continuous use.

My Presario CQ5300F has two slots — do I need matching modules?

The board accepts up to 4 GB across two sockets; this single 2 GB stick works alone or paired with another identical DDR2 800 DIMM.
