  • 288-pin DIMM fits standard desktop slots
  • Non-ECC unbuffered design ensures broad compatibility

16 GB DDR5 desktop module

This 16 GB DDR5 module is built for desktop systems that need a single unbuffered DIMM running at 1.10 V. It fits standard 288-pin slots and is validated as a direct replacement for the Samsung M323R2GA3BB0-CQK part number. The kit suits builders upgrading mainstream workstations or home PCs.

DDR5 4800 speed rating

The decisive specification is the DDR5 4800 (PC5-38400) rating, which sets the maximum data rate the memory controller will see. If your platform only supports lower DDR5 speeds this module will down-clock, but it cannot exceed 4800 MT/s without manual overclocking. Confirm the motherboard QVL before purchase.

Sustained-load behaviour

Under continuous workloads the module operates at the standard 1.10 V DDR5 voltage, keeping power draw predictable during long render or compile sessions. Non-ECC unbuffered organisation means error correction is handled by the CPU, so data integrity scales with the processor’s own capabilities. Thermal performance follows the JEDEC baseline for this density and speed.

Questions about this item

What does the DDR5 4800 speed mean for my desktop once the module is installed?

The module operates at 4800 MT/s, the rated data rate for DDR5 4800, so the memory controller can move data at that speed when the system is configured to run at the JEDEC standard frequency.

How does the PC5-38400 designation relate to the bandwidth I will see?

PC5-38400 is the peak transfer-rate label for DDR5 4800; it represents the theoretical maximum bandwidth in megabytes per second that the module can deliver under standard timing.

Will the 288-pin DIMM fit my motherboard's memory slots?

Yes, the 288-pin DDR5 DIMM form factor matches the standard desktop DDR5 slot, so it will seat correctly in any board that supports DDR5 memory.
