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.

Otázky k tomuto produktu

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.
