A-Tech 4GB DDR3 1066MHz PC3-8500 CL3 1.5V 204-Pin SO-DIMM laptop RAM

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.
