DDR4 vs DDR5 Spec Breakdown
Memory Speed
The OWC 16GB DDR5 4800MHz ECC UDIMM offers a base frequency of 4800MHz. This is a significant jump from the OWC 64GB DDR4 3200MHz ECC UDIMM Kit, which runs at 3200MHz. Higher bandwidth allows data to move faster between the memory and the processor. For workstations handling large datasets, this speed difference can reduce processing times. The DDR5 standard provides a wider data path and improved efficiency compared to the older DDR4 technology. You will notice this performance gain in memory-intensive applications.
Total Capacity
The OWC 64GB DDR4 3200MHz ECC UDIMM Kit provides a total of 64GB of RAM. It consists of four 16GB modules. The OWC 16GB DDR5 4800MHz ECC UDIMM is a single stick with 16GB of capacity. If you need to run multiple virtual machines or edit high-resolution video, the larger 64GB kit allows for more simultaneous tasks without swapping data to the storage drive. The DDR5 module is better suited for systems that only require a small amount of additional memory or for upgrading a single slot.
Voltage Requirements
Power efficiency differs between the two modules. The OWC 16GB DDR5 4800MHz ECC UDIMM operates at 1.1V. The OWC 64GB DDR4 3200MHz ECC UDIMM Kit requires 1.2V. Lower voltage reduces heat generation and power consumption. This is important for servers and workstations that run continuously. The DDR5 module is slightly more energy-efficient. However, the difference is small. Both modules are designed to meet strict OEM specifications for stability and compatibility with enterprise-grade hardware.
CAS Latency
Latency affects how quickly the memory responds to commands. The OWC 64GB DDR4 3200MHz ECC UDIMM Kit has a CAS Latency of CL22. The OWC 16GB DDR5 4800MHz ECC UDIMM has a CAS Latency of CL40. A lower number generally means faster response times. However, DDR5 runs at a much higher frequency. The absolute latency in nanoseconds is often comparable or better in DDR5 despite the higher CL number. For most users, the speed increase outweighs the latency difference.
Form Factor
Both modules use the 288-pin UDIMM form factor. This means they fit into standard desktop and workstation slots. The OWC 64GB kit includes four sticks, filling all available DIMM slots in many systems. The OWC 16GB module is a single stick, leaving three slots open for future expansion. If your motherboard has only two slots, the DDR5 kit allows you to keep one slot free. If you have four or more slots, the DDR4 kit fills them completely for maximum capacity.
Choose the right OWC RAM for you
Users needing maximum capacity for heavy workloads
This kit provides 64GB total capacity using four 16GB modules. It runs at 3200MHz with CL22 latency and 1.2V. If your workstation requires large memory pools for virtualization or data processing, this higher capacity option supports your intensive tasks without bottlenecking.
Users prioritizing speed and modern architecture
This module delivers 4800MHz speed with CL40 latency and 1.1V operation. It uses the DDR5 generation for higher bandwidth. Choose this if your system supports DDR5 and you need faster data transfer rates for specific workstations, despite the lower 16GB capacity.
Professionals requiring extensive multi-tasking memory
With 64GB spread across four sticks, this kit maximizes available memory space. It maintains ECC support for data integrity. This configuration is ideal if you run multiple large applications simultaneously, as the higher capacity reduces the need to swap data to slower storage.

Frequently asked questions
Can I mix the 64GB DDR4 kit with the 16GB DDR5 module?
No, you cannot mix these modules. They use different memory generations, DDR4 and DDR5, which are physically and electrically incompatible. Your motherboard supports only one generation at a time. You must choose either the DDR4 kit or the DDR5 module for your system to function correctly.
Is ECC support available on both memory options?
Yes, both products feature ECC support. This error correction capability helps maintain data integrity during professional tasks. Whether you select the high-capacity DDR4 kit or the faster DDR5 module, you get the same protection against single-bit memory errors for your workstation or server.
Which module is better for single-slot upgrades?
The OWC 16GB DDR5 4800MHz ECC UDIMM is better for single-slot upgrades. It is a single 16GB stick designed to fit into one memory slot. The 64GB option comes as a four-module kit, requiring four available slots on your motherboard to install the full capacity.
What is the main speed difference between these two kits?
The DDR5 module runs at 4800MHz, while the DDR4 kit runs at 3200MHz. This 1600MHz difference means the DDR5 option offers higher bandwidth for data transfer. If raw speed is your priority, the DDR5 module provides a faster data rate than the older DDR4 standard.
Does the 64GB kit include four separate sticks?
Yes, the 64GB kit consists of four 16GB modules. You need to install all four sticks to achieve the total 64GB capacity. This configuration is ideal for systems with four memory slots that require large amounts of RAM for virtualization or heavy data processing workloads.
Are both modules unbuffered DIMMs?
Yes, both products use the UDIMM form factor. This stands for Unbuffered DIMM, which is standard for most workstations and servers. It allows for direct communication with the memory controller without the latency added by registered memory, making both options suitable for general professional use.
