4GB DDR3 1066MHz SO-DIMM for laptops

This 4GB DDR3 SO-DIMM module runs at 1066MHz with CL3 latency and 1.5V operation. It is built as a compatible replacement for the Corsair CMSA8GX3M2A1066C7 part. The unbuffered, non-ECC design targets laptops, notebooks and all-in-one systems that accept 204-pin DDR3 memory.

DDR3 1066MHz interface limits

The DDR3 1066 standard caps bandwidth at the PC3-8500 rate, so throughput cannot exceed what the memory controller and bus allow at this frequency. CL3 timing is fixed by the module and cannot be tightened without stability risk. Systems requiring ECC, registered modules or voltages other than 1.5V will not accept this stick.

Single 4GB module capacity

A single 4GB stick adds modest headroom for everyday multitasking and typical office workloads on supported platforms. Memory-intensive tasks such as virtualisation, large media editing or modern gaming will exhaust the available capacity quickly. Buyers needing more than 4GB total must populate additional slots with compatible modules.

商品問答

Is this single 4 GB module the right choice if my laptop has two SO-DIMM slots and I want 8 GB total?

Yes, this is a single 4 GB DDR3 SO-DIMM; adding a second identical module will give 8 GB in dual-channel mode if your platform supports it.

What does the PC3-8500 rating mean for actual throughput in my laptop?

PC3-8500 is the JEDEC designation for DDR3 1066 MHz operation, so the module runs at that data rate once installed.

Will the 204-pin DDR3 SO-DIMM interface work in any notebook that takes DDR3 memory?

The module uses the standard 204-pin DDR3 SO-DIMM form factor and 1.5 V voltage required by DDR3 laptop slots.
