What this module is

A-Tech supplies a 16GB DDR5 DIMM rated at 5600MHz with CL40 timings and 1.1V operation. The unbuffered non-ECC stick uses Samsung chips and matches the Samsung M323R2GA3DB0-CWM part number for direct replacement.

Who this suits

Desktop owners needing a single 16GB DDR5 module to replace a failed stick or add capacity will find the spec match useful. Systems that require ECC, registered memory or a different voltage should look at other modules.

Installation notes

The 288-pin DIMM seats in any standard DDR5 desktop slot without extra tools or configuration. Most issues arise when the motherboard firmware does not recognise the 5600MHz speed or when mixed kits prevent the system from posting.

Questions about this item

Will this 16GB DDR5 5600MHz module fit my desktop motherboard?

The module uses a standard 288-pin DDR5 DIMM form factor; check your motherboard manual to confirm it supports DDR5 memory before installing.

Does this RAM require a heat spreader or extra cooling?

No heat spreader is included; the module runs at the standard 1.1V DDR5 voltage and is designed to operate within normal case airflow.

Can I mix this CL40 stick with my existing DDR5 memory?

Mixing modules with different CAS latencies is possible but the system will run all sticks at the slowest timing; for best stability use identical modules.
