System-Specific DDR3 Upgrade

This 8 GB kit contains two 4 GB DDR3-1066 SO-DIMM modules built for Compaq Presario Cq56-200Sv and Cq56-200La notebooks. It targets owners of those models who need to reach the platform's maximum supported memory.

DDR3-1066 Interface Limits

The modules run at 1066 MHz with PC3-8500 bandwidth, CL7 latency and 1.5 V unbuffered operation. Performance is bounded by the DDR3-1066 memory controller in the host laptop; faster DDR3 speeds will downclock to this rate.

Two-Stick SO-DIMM Build

Each stick uses a 204-pin edge connector and 2Rx8 organisation with major-brand chips. No heat spreader is fitted, keeping the profile low for tight SODIMM slots. The pair installs side by side to populate both memory channels.
