Speed, Latency, and Form Factor
Memory Speed
The Samsung 16GB DDR5 5600MHz UDIMM operates at 5600MHz, while the Samsung 16GB DDR5 4800MHz UDIMM runs at 4800MHz. Higher clock speeds allow more data to transfer per second. This means the 5600MHz module can handle bandwidth-intensive tasks faster. You will see better performance in applications that rely heavily on memory throughput. The 4800MHz option is sufficient for basic desktop use. However, for gaming or video editing, the faster module provides a tangible advantage. The difference in MHz is clear and directly impacts system responsiveness.
Cas Latency
The Samsung 16GB DDR5 5600MHz UDIMM lists a CAS latency of CL46. The Samsung 16GB DDR5 4800MHz UDIMM does not provide a CAS latency value in its specifications. CAS latency measures the delay before data is available. While CL46 might seem high, it is standard for this speed tier. Without the latency spec for the 4800MHz module, we cannot fully compare timing efficiency. Generally, higher speeds come with higher latency numbers. You should check the exact timings if low latency is critical for your workload. The available data favors the 5600MHz module for having a stated latency value.
Form Factor
Both modules use the UDIMM form factor. This stands for Unbuffered DIMM, which is the standard for most desktop computers. They are compatible with standard desktop motherboards that support DDR5 memory. The Samsung 16GB DDR5 5600MHz UDIMM is described as a 288-pin module. The Samsung 16GB DDR5 4800MHz UDIMM is also a UDIMM, implying the same pin count. This shared form factor ensures you can swap between them if your motherboard supports the speed. There is no physical difference in how they install. Both fit standard desktop slots without requiring special adapters or slots.
Voltage
The Samsung 16GB DDR5 5600MHz UDIMM operates at a standard JEDEC DDR5 voltage of 1.1V. The Samsung 16GB DDR5 4800MHz UDIMM also uses the standard DDR5 voltage, though it is not explicitly listed in the provided data. DDR5 memory typically runs at 1.1V, which is lower than older DDR4 standards. This lower voltage helps with power efficiency and heat generation. Since both are standard DDR5 modules, they likely share this electrical characteristic. You do not need to worry about power supply compatibility for either. The 5600MHz module explicitly confirms this standard voltage, providing clarity for your build.
Rank Configuration
The Samsung 16GB DDR5 5600MHz UDIMM is a 1Rx8 Single Rank module. The Samsung 16GB DDR5 4800MHz UDIMM does not specify its rank configuration in the provided data. Single rank modules use memory chips on one side of the PCB. This can sometimes offer better compatibility with older motherboards or specific memory controllers. Dual rank modules use chips on both sides. Since the 5600MHz module is explicitly single rank, it may be easier to install in systems with limited memory slot support. The 4800MHz module's rank is unknown, so you should verify compatibility with your motherboard manual if rank matters for your setup.
Which Samsung DDR5 kit fits you
Users needing maximum bandwidth for heavy tasks
Choose the 5600MHz module if your workflow demands higher data throughput. Its 5600MHz speed offers more bandwidth than the 4800MHz alternative. This helps reduce bottlenecks in memory-intensive applications. The 1Rx8 configuration supports efficient single-rank access. You gain better performance for workloads that stress memory capacity and transfer rates.
Budget-conscious builders prioritizing standard DDR5 speeds
Select the 4800MHz option if you need reliable base performance without premium costs. It provides standard DDR5 speeds suitable for general desktop use. The 16GB capacity handles everyday multitasking and standard applications effectively. This module ensures compatibility with mainstream desktop systems while delivering consistent, stable operation for common user needs.
Gamers seeking higher frame rates in CPU-bound titles
The 5600MHz speed benefits gaming by increasing memory bandwidth. This supports faster data access for CPU-intensive games. Higher frequencies can improve frame pacing in titles that rely heavily on memory speed. The 16GB size ensures you have enough space for modern game assets without swapping.

Frequently asked questions
Are both Samsung DDR5 modules non-ECC?
Yes, both the Samsung 16GB DDR5 4800MHz UDIMM and the 16GB DDR5 5600MHz UDIMM feature non-ECC support. This means they do not include error-correcting code capabilities. This configuration is standard for most consumer desktop computers. It prioritizes cost-efficiency and speed over the data integrity features found in server-grade memory modules.
What is the physical size of these RAM sticks?
Both modules use the standard UDIMM form factor for desktop PCs. The 4800MHz model measures approximately 6 inches in length and weighs 0.6 ounces. The 5600MHz variant is slightly shorter at 5.25 inches long. Both are designed to fit into standard desktop motherboard DIMM slots without requiring special cooling solutions or larger cases.
Can I mix these two speeds in one system?
You should not mix these specific modules if you want stable performance. The 5600MHz kit runs significantly faster than the 4800MHz version. Mixing them would force the faster module to slow down to match the slower one. For optimal stability and speed, use two identical modules of the same speed rating in your dual-channel configuration.
Which model is better for general desktop use?
The Samsung 16GB DDR5 4800MHz UDIMM is the practical choice for standard desktop computing. It provides stable memory performance for everyday tasks like web browsing and office work. The 5600MHz version offers higher bandwidth, but the 4800MHz speed is sufficient for most users who do not require maximum data throughput for heavy professional applications.
Does the 5600MHz version have a different model number?
Yes, the Samsung 16GB DDR5 5600MHz UDIMM carries the model number M323R2GA3DB0-CWM. In contrast, the 4800MHz variant is identified as M323R2GA3BB0-CQK. These distinct model numbers help you verify you are purchasing the correct speed rating. Always check the model number to ensure compatibility with your motherboard's supported memory speeds.
Is ECC support available on either of these kits?
Neither the 4800MHz nor the 5600MHz Samsung UDIMM offers ECC support. Both are classified as non-ECC memory. This is typical for consumer-grade desktop memory. If you require error correction for critical data integrity, you would need to look for server-grade ECC modules instead of these standard UDIMM options designed for general PC use.
