Product Q&A

Q: Is this compatible with desktop PCs?

A: No. This is ECC Registered (RDIMM) memory designed for servers and workstations. Most consumer desktop systems require unbuffered (UDIMM) memory.

Q: Can this be mixed with non-ECC or UDIMM memory?

A: No. RDIMM memory cannot be mixed with UDIMM or non-ECC modules.

Q: What does DR x4 mean?

A: DR x4 refers to the memory chip organisation, commonly used in enterprise environments for improved reliability and error handling.

Q: Will this work at lower speeds?

A: Yes. The module may downclock to match the system’s supported memory speed.

Q: Do I need drivers?

A: No. Memory is detected automatically by the system BIOS/UEFI.
