Replacement for Samsung DDR5 Modules

This A-Tech module is built as a direct replacement for Samsung part numbers M323R1GB4DB0-CWM and M323R1GB4PB0-CWM. It delivers 8 GB of DDR5 memory in a single unbuffered DIMM for desktop systems. The stick uses Samsung chipset components and runs at the standard 1.1 V.

DDR5 5600 Speed and Timing Limits

The module operates at 5600 MT/s with a CAS latency of CL40, matching the PC5-44800 designation. DDR5 architecture moves the voltage regulator onto the DIMM itself, so the board must supply a clean 1.1 V rail. Bandwidth and latency are fixed by the JEDEC profile; no higher XMP or EXPO profiles are present on this part.

Simple DIMM Installation and Common Issues

Installation follows the standard 288-pin DDR5 DIMM procedure: align the notch, press firmly until the retention clips click, and verify seating. The most common problems are mixing this stick with different speeds or capacities, which forces the system to run at the lowest common settings, and forgetting to enable the correct memory profile in BIOS if the board defaults to a lower speed.

Questions about this item

Will this 8 GB DDR5 module fit a motherboard with standard 288-pin DDR5 DIMM slots?

Yes, the module uses the 288-pin DDR5 DIMM form factor, which is the standard desktop DDR5 slot layout.

Does the 1.10 V operating voltage match the DDR5 baseline so no manual BIOS voltage change is needed?

The module runs at the DDR5 standard 1.10 V, so it will operate at the default voltage without any BIOS adjustment.

Is the CL40 latency at 5600 MT/s suitable for a typical desktop board that only supports JEDEC speeds?

CL40 is the standard JEDEC timing for DDR5-5600, so the module will run at its rated speed on any board that follows the JEDEC profile.
