M323R2GA3DB0-CWM0D Samsung 16GB DDR5 5600MHz Memory

Samsung M323R2GA3DB0-CWM0D 16GB DDR5 Memory

Product family overview  

The Samsung M323R2GA3DB0-CWM0D is a single-module 16GB DDR5 desktop memory solution designed to deliver high bandwidth, low voltage operation, and reliable single-rank performance for modern PCs and workstations. Built to the JEDEC DDR5 standard, this UDIMM (unbuffered DIMM) module operates at an effective data rate of 5600 MT/s (PC5-44800 / sometimes labeled PC5-5600B depending on platform naming), uses a 288-pin form factor, and runs at a nominal supply voltage of 1.10 V—helping platforms achieve higher throughput while controlling power draw and thermal output. 

These primary attributes make the M323R2GA3DB0-CWM0D an attractive, standardized upgrade option for users seeking a balance between price, capacity, and performance in mainstream and enthusiast desktop systems.  

Performance and practical benefits

Higher bandwidth for modern applications

DDR5-5600 offers substantially greater raw bandwidth than DDR4-based modules; a 5600 MT/s module like Samsung’s raises the ceiling for memory-bound workloads such as content creation (video encoding, image processing), large dataset manipulation, virtualization, and heavy multitasking. For gamers and prosumers, higher sustained memory throughput reduces frame-time variance in memory-sensitive scenes and accelerates texture streaming and physics calculations when the CPU interacts heavily with system RAM.  

Energy efficiency and thermal considerations

Operating at 1.10 V (JEDEC nominal), DDR5 modules reduce power consumption relative to higher-voltage predecessors while enabling higher speeds. This lower voltage helps desktop systems run cooler under sustained loads, and is particularly relevant in compact or thermally constrained builds where case airflow is limited. The lower nominal voltage also benefits multi-module configurations and densely populated motherboards where cumulative power draw matters. 

Single-rank 1Rx8: compatibility and density tradeoffs

Single-rank (1R) modules generally have simpler signaling and can be a better first-choice for platform compatibility, particularly on motherboards that can be sensitive to rank/population configurations. A 1Rx8 organization means the module is built from x8 devices and presents a single rank to the memory controller—this can improve compatibility with many consumer motherboards while still enabling straightforward capacity scaling (e.g., 2×16GB for 32GB).  

Compatibility checklist 

Motherboard and CPU support

• Confirm that your motherboard supports DDR5 memory (DDR4 and DDR5 are not interchangeable; they use different slots and electrical specs).
• Check the motherboard QVL (Qualified Vendor List) for part numbers if you want guaranteed validation; Samsung modules are commonly supported but QVL lookup confirms tested compatibility for your exact board firmware version.
• Verify maximum supported DIMM speed—some motherboards will run DDR5-5600 natively, while others may require enabling XMP/EXPO profiles or BIOS tuning to achieve full rated speeds.

If you are building on a platform released in the DDR5 era (modern Intel or AMD desktop chipsets that explicitly support DDR5), the M323R2GA3DB0-CWM0D is typically supported as a standard UDIMM part. However, always check specific motherboard documentation and BIOS updates when pushing memory to higher speed bins.  

BIOS/firmware and XMP/EXPO considerations

Many DDR5 modules ship with JEDEC standard timings that allow them to run at the advertised speed under JEDEC or manufacturer profiles. To run at a platform’s advertised XMP/EXPO speed (if provided), you may need to enable the appropriate profile in the BIOS. Samsung’s module here is advertised as JEDEC-spec DDR5-5600; if your board exposes performance profiles, enabling them may ensure the module runs at its rated timings and voltage. 

Typical use cases and target audiences

PC builders and upgraders

For users upgrading older systems (that support DDR5), a 16GB DDR5-5600 UDIMM is an excellent balance between cost and capability—offering enough capacity for modern gaming and productivity while adding the speed advantage of DDR5. Builders seeking a baseline “future-proof” configuration often pick 2×16GB kits later to reach 32GB dual-channel configurations for heavier workloads. Retail listings for the M323R2GA3DB0 part indicate it’s sold both singly and by resellers as an individual module for incremental upgrades.  

Gamers and esports enthusiasts

While gaming rarely saturates memory bandwidth the way content creation can, faster RAM can reduce minimal frame drops and improve consistency in CPU-bound scenarios—especially at lower resolutions where the CPU matters more. Gamers who stream or run concurrent applications will see a more tangible benefit from increased bandwidth and capacity. Samsung’s 5600 MT/s 16GB module provides a low-latency, high-throughput base for those builds.  

Small workstations and creators

Video editors, 3D artists, and multitasking professionals benefit from a combination of sufficient memory capacity and high throughput; a 16GB stick is often used as part of a larger kit (2× or 4×) to reach 32–64GB total, at which point DDR5-5600 helps reduce swap activity and accelerate memory-intensive operations. As a JEDEC-compliant module from Samsung, it provides the stable baseline many creators prefer when assembling predictable, reliable workstation builds.  

Physical and electrical design details

Form factor and mechanical notes

The module adheres to the 288-pin DIMM mechanical standard; it installs into standard DDR5 UDIMM slots. Because it is unbuffered and non-ECC, the module lacks the additional register/buffer chips that appear on server DIMMs, making it ideal for consumer hardware where simplicity and lower latency are desirable. Many retail images show the bare PCB module without a large heatspreader, which reduces overall module height and improves fit in builds with tall CPU coolers.  

Thermal behavior and recommended cooling

DDR5 JEDEC modules such as this one are engineered for normal desktop temperatures. If you run high-TDP CPUs, frequent benching, or overclocking, consider airflow over the DIMM area or aftermarket low-profile heatspreaders—especially if you populate all DIMM slots, which can raise temperatures inside the chassis. Many users pair these modules with motherboards that provide passive DIMM-slot airflow management via case fans oriented to move air across the memory banks.  

DDR5-5600 vs. common alternatives

DDR5-5600 vs DDR4 (general)

Compared with DDR4, DDR5 at 5600 MT/s offers both higher peak bandwidth and features introduced in DDR5 such as improved power management (usually via on-DIMM power management ICs on the module) and double the burst length—this yields better performance for demanding multi-threaded workloads and scaling on multicore CPUs. DDR5’s baseline voltage is lower, which translates into savings in power at similar or better performance tiers. However, DDR5 requires a compatible motherboard and CPU.  

DDR5-5600 vs DDR5-4800

DDR5-5600 provides roughly ~16.7% higher raw data rate than DDR5-4800. In practice, the real-world benefit depends on workload memory sensitivity: memory throughput-bound tasks (certain simulation workloads, large database caching, scientific computing) will scale more noticeably, while lightly memory-bound tasks will see modest to negligible differences. Pricing and availability often guide the choice—if DDR5-5600 is cost-competitive, it’s a sensible step up.  

Technical glossary: terms explained

UDIMM

Unbuffered DIMM—standard consumer desktop memory without register/buffer chips. Unbuffered modules tend to have slightly lower latency than registered ECC modules used in servers.  

1Rx8 (single rank x8)

Refers to the internal organization of memory chips on the module. “1R” means single rank; “x8” indicates each DRAM device has an 8-bit data width. This impacts how the memory controller addresses the module and can affect compatibility and performance characteristics in multi-DIMM systems.  

PC5-44800 / PC5-5600B

Marketing/standard labels for DDR5-5600 class modules: “PC5-44800” denotes the theoretical peak bandwidth (in MB/s), and platform vendor naming conventions sometimes append suffixes like “B” depending on the profile or timing pack. JEDEC timing/voltage standards define the official operating points.
