SAMSUNG M323R2GA3BB0-CQK DDR5-4800 16GB 1Rx8 PC5-38400R CL40 1.1V desktop RAM

SKU CH-6R23-MCJ1J

16 GB DDR5-4800 desktop module with single-rank x8 organisation, CL40 latency and 1.1 V operation

  • DDR5-4800 speed delivers responsive multitasking performance
  • 16 GB single module provides ample capacity for modern workloads
  • 1 V operation reduces power draw and heat
  • CL40 latency supports quick data access
  • U-DIMM form factor fits standard desktop memory slots

Single-rank DDR5-4800 UDIMM module

This Samsung M323R2GA3BB0-CQK is a 16 GB desktop memory stick built on DDR5 technology. It runs at 4800 MT/s with a CL40 latency and operates at the standard 1.1 V. The single-rank 1Rx8 layout and PC5-38400R rating identify it as a registered UDIMM for mainstream platforms.

Not for ECC or high-capacity kits

Builders who need error-correcting code support cannot use this non-ECC module. Systems that require multi-rank densities or matched multi-stick kits for quad-channel bandwidth should look at alternative configurations. Buyers wanting speeds above 4800 MT/s or lower latencies than CL40 must choose a different specification.

Registered UDIMM form factor

The decisive specification is the registered UDIMM form factor combined with non-ECC operation. Only motherboards that explicitly support registered non-ECC DDR5 DIMMs will accept this part.

Questions about this item

How much heat does the 1.1V DDR5-4800 module produce during continuous operation?

The module runs at the standard DDR5 voltage of 1.1V, which is lower than previous generations and helps limit heat output during all-day workloads.

Does my motherboard need to support RDIMM and non-ECC DDR5 to use this 16GB stick?

Yes, the module is an RDIMM with non-ECC error correction, so the board must accept registered DDR5 DIMMs without ECC functionality.

Can I add this PC5-38400R CL40 stick to an existing DDR5 kit running at a different speed?

The system will downclock all modules to the lowest common speed and loosest timings, so mixing with faster or tighter-timed DDR5 will reduce overall performance.
