System-specific DDR3 SODIMM

This 4 GB DDR3 module runs at 1600 MHz with CL11 timing and 1.5 V operation. It uses a 204-pin SO-DIMM form factor and unbuffered, non-ECC architecture. The kit contains a single stick built with major-brand chips and no heat spreader. Computer Memory Solutions guarantees compatibility with Asus S56Ca series notebooks.

Sustained-load behaviour

Under continuous workloads the memory maintains its rated 1600 MHz speed and 11-11-11 timings at standard voltage. The dual-rank 2Rx8 organisation supports stable throughput for everyday multitasking and office applications. Without a heat spreader the module relies on the notebook’s internal airflow, which is sufficient for typical sustained use in the validated platform.

Pre-order checks

Verify your notebook is an Asus S56Ca series model before ordering. Confirm the system has a free 204-pin DDR3 SO-DIMM slot and supports 1.5 V unbuffered non-ECC modules. The platform maximum is 16 GB across two sockets, so total capacity after this upgrade must not exceed that limit. Ensure the BIOS is current for reliable memory initialisation.

Questions about this item

Does the 1.5V DDR3 1600MHz module run hot or draw extra power during all-day use?

It operates at the standard 1.5V for DDR3, so heat and power draw stay within normal limits for this generation.

What must my Asus S56Ca already have for this 204-pin SODIMM to work?

An available 204-pin DDR3 SO-DIMM slot and a BIOS that accepts PC3-12800 CL11 memory.

Will this CL11 1600MHz stick run correctly alongside the original memory still installed in my S56Ca?

The system will clock both modules to the lowest common speed and tightest shared timings.
