4GB DDR3 1600MHz desktop module

This A-Tech module is a 4GB DDR3 DIMM rated at 1600MHz with CL11 latency and 1.5V operation. It is built as a direct replacement for several Corsair part numbers including CMZ8GX3M2A1600C9B. The unbuffered, non-ECC design fits standard desktop platforms that accept DDR3 memory.

Suits owners of the listed Corsair kits needing

It matches the speed, voltage and timing of the original modules so it can fill an empty slot or replace a failed unit. Systems that require ECC, registered memory, or a different DDR generation will not be compatible with this module.

Handles everyday desktop workloads

Four gigabytes is enough for web browsing, office applications and media playback on older DDR3 platforms. Heavier tasks such as modern gaming, video editing or running multiple virtual machines will exceed the capacity of a single 4GB module.

Questions about this item

Will this 4 GB DDR3 module fit my Corsair CMZ8GX3M2A1600C9B kit?

Yes, it is a compatible replacement for the CMZ8GX3M2A1600C9B and matches the DDR3 1600 CL11 1.5 V specification.

Does my motherboard need to support 240-pin DDR3 DIMMs for this to work?

The module uses the standard 240-pin DDR3 DIMM form factor, so your board must accept DDR3 desktop memory.

Can I add this stick alongside my existing Corsair memory without changing BIOS settings?

It runs at the same 1600 MHz speed and 1.5 V voltage, so it will operate at the rated CL11 timings automatically.
