Capacity and purpose

This A-Tech module delivers 32GB of DDR5 desktop memory running at 4800 MT/s with CL40 latency. It is an unbuffered, non-ECC DIMM built as a compatible replacement for the Samsung M323R4GA3BB0-CQK part number.

Installation notes

The stick uses a standard 288-pin DDR5 DIMM form factor and operates at the 1.10V DDR5 baseline voltage. Alignment keys prevent backward insertion; press evenly until the retention clips click. No heat spreader is fitted, so airflow across the PCB is the only cooling path.

Compatibility checklist

Confirm that your motherboard and processor officially support DDR5 4800 unbuffered non-ECC UDIMMs and that a free 288-pin slot is available. Verify the maximum per-slot capacity and total system limit in the board manual before ordering.

Questions about this item

Will this 32GB DDR5 4800 module fit my desktop motherboard?

It is a 288-pin DDR5 DIMM, so it fits motherboards with DDR5 DIMM slots. Check your board's manual for supported speeds and maximum capacity per slot.

Is this module compatible with my existing DDR5 memory?

It runs at 4800MHz CL40 1.10V. Mixing works best when speed, latency and voltage match your current sticks. Verify your motherboard's qualified vendor list for tested combinations.

Does this module include a heat spreader?

No heat spreader is included. The bare PCB design fits tighter clearances and works with standard CPU coolers. Ensure your case airflow handles the module's operating temperature.
