2GB DDR2 SO-DIMM for Acer Aspire 4730

This 200-pin DDR2 SO-DIMM module delivers 2GB of system memory at 667MHz with CL5 latency. It operates at 1.8V and uses an unbuffered, non-ECC design. The CM256645300SO is built specifically for compatible Acer Aspire 4730 and 4730Z series laptops requiring PC2-5300 standard memory.

Suits owners upgrading a supported Acer Aspire model

This module suits owners of an Acer Aspire 4730 or 4730Z series laptop needing a direct 2GB DDR2 replacement or expansion. Builders working on any other platform, including different Acer series or desktop systems, should look elsewhere because the 200-pin SO-DIMM form factor and DDR2 voltage are not interchangeable with other memory types.

Single stick enables immediate installation

The package contains one 2GB memory stick with major brand chips, ready to install without additional components or software. No heat spreader is included, keeping the low-profile height suitable for tight laptop chassis. The limited lifetime warranty from Computer Memory Solutions covers the module itself when purchased directly from the manufacturer.

Questions about this item

What laptop slot must be free to install this CM256645300SO module?

Your Acer Aspire 4730 or 4730Z needs an available 200-pin SO-DIMM socket that accepts 1.8 V DDR2 memory.

Can this 2 GB stick run together with the original memory already fitted in my 4730Z?

Yes, provided the original module is also a 200-pin DDR2 SO-DIMM; the system will operate both at the lower of the two speeds.

How can I verify the stick is recognised at the correct 667 MHz speed after fitting it?

Open the BIOS or a system-information tool such as CPU-Z and confirm the memory frequency reads 667 MHz with CL5 timings.
