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.

이 상품에 대한 질문
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.
