UDIMM vs SODIMM Comparison
form factor
The most critical difference lies in the physical design. Product A uses a 288-pin UDIMM format, which is the standard for desktop computers. Product B utilizes a 260-pin SODIMM design, intended for laptops and mini PCs. You cannot install the UDIMM in a laptop slot, nor the SODIMM in a desktop motherboard. The pin count and physical length differ significantly. Product A is longer and heavier, measuring 5.3 inches. Product B is compact, designed to fit tight spaces. Choosing the wrong form factor will prevent your system from booting. This distinction dictates which hardware you can actually use.
compatible device
Your choice depends entirely on your computer type. Product A is built for desktop PCs and workstations. It requires a motherboard with standard DIMM slots. Product B is designed for laptops, notebooks, and All-In-One systems. It fits into SODIMM slots found in portable devices and compact mini PCs. If you have a desktop tower, you must select the UDIMM. If you are upgrading a laptop, the SODIMM is the only option. The compatibility is mutually exclusive. Using the wrong module will not work due to physical and electrical differences in the socket.
memory speed
Both modules offer identical performance specifications regarding speed. Product A runs at 2400MHz, labeled as PC4-2400T. Product B also operates at 2400MHz with the same PC4-2400T rating. This means they handle data transfer rates equally well within their respective systems. Neither module provides a speed advantage over the other. If your system supports 2400MHz, both will perform at that baseline. You will not see faster frame rates or quicker load times from one over the other based on speed alone. The timing characteristics are matched.
cas latency
Latency affects how quickly the RAM responds to commands. Both Product A and Product B feature a CAS latency of CL17. This value indicates the delay between the memory controller requesting data and the data being available on the pins. Since both modules share this exact specification, there is no difference in access time. You will experience the same responsiveness in everyday tasks. Whether you are browsing the web or editing documents, the latency remains constant. This spec does not differentiate the two products.
voltage
Power efficiency is identical for both modules. Product A operates at 1.2V, which is the standard voltage for DDR4 memory. Product B also uses 1.2V. This low voltage helps reduce heat generation and power consumption compared to older DDR3 standards. Since both use the same voltage, there is no impact on your power supply or battery life relative to this spec. Neither module runs hotter or cooler due to voltage differences. The electrical requirements are perfectly matched.
Choose the right RAM for your system
Desktop PC owners needing a simple upgrade
You need the 288-pin UDIMM form factor for your desktop motherboard. This module fits standard desktop slots and provides 16GB of capacity at 2400MHz. It runs at 1.2V with CL17 latency. The dual rank configuration ensures stable performance for general computing tasks and multitasking on your desktop workstation.
Laptop or mini PC users upgrading memory
Your device requires the compact 260-pin SODIMM format. This module is designed specifically for laptops, notebooks, and mini PCs. It offers the same 16GB capacity and 2400MHz speed as the desktop version but in a smaller physical package. It fits into the SODIMM slots found in portable and small form factor systems.
Buyers seeking universal compatibility with non-ECC
Both options provide non-ECC unbuffered memory, which is standard for consumer systems. If your desktop supports standard UDIMM slots, this choice ensures proper fit and function. You get reliable 1.2V operation and plug-and-play installation. The specifications match the requirements for most modern desktop computers without needing specialized server-grade components.
