Buyer Questions Answered (FAQ)

What is the difference between RDIMM and UDIMM?
RDIMMs (Registered) include a hardware register that buffers signals to improve stability in high-capacity server environments, whereas UDIMMs (Unbuffered) are typically for desktops and lack this buffer.

Is this memory compatible with my desktop PC?
No. This is ECC Registered server memory and will not function in standard consumer motherboards. It requires a server or workstation motherboard that supports RDIMMs.

What does "Single Rank 1Rx8" mean?
It refers to how the memory chips are organized on the module. Single-rank modules often provide better performance in specific server configurations and exert less electrical stress on the memory controller.

Compared to Previous Generation

• Speed Boost: 3200MT/s provides a significant bandwidth increase over older 2666MT/s or 2933MT/s DDR4 standards.
• Thermal Efficiency: Modern 16Gb die density allows for cooler operation and higher reliability than older 8Gb density components.
• Wider Compatibility: Specifically tuned for optimized performance on the latest generations of Intel Xeon Scalable and AMD EPYC processors.
