Kit Contents
This kit contains two 4 GB DDR3 SO-DIMM modules for a total of 8 GB. It targets owners of the listed Compaq Presario CQ57 notebooks who need a straightforward memory upgrade. The unbuffered non-ECC design matches the original specification for these systems. Installation uses the standard 204-pin slot found in the compatible models.
Sustained Operation
Rated at 1066 MHz with CL7 7-7-7 timings and 1.5 V, the modules maintain their specified speed under continuous workloads. The major-brand chipset and 2Rx8 organisation provide stable data integrity during extended sessions. No heat spreader is fitted, so the notebook’s existing cooling handles thermal load.
Deciding Specification
The 204-pin DDR3 1066 CL7 form factor is the single detail that determines fit. Only notebooks accepting PC3-8500 SO-DIMM memory at this voltage and latency will recognise the full capacity. Buyers whose laptops require a different pin count, voltage or DDR generation cannot use this kit.

이 상품에 대한 질문
How much heat does the 1.5V DDR3 1066 kit produce during all-day use?
The modules run at standard 1.5 V DDR3 voltage with no heat spreader, so they generate only modest warmth typical for low-power SO-DIMMs.
What must my laptop already have for these 204-pin SO-DIMMs to install?
Your notebook needs two free DDR3 SO-DIMM slots and a chipset that accepts PC3-8500 1066 MHz unbuffered memory.
Will the CL7 2Rx8 sticks work beside the original 4 GB module in my CQ57-314NR?
Yes, the kit is validated for the CQ57-314NR and other listed Presario models, so it will run alongside or replace the factory memory.
