FAQs

Q: Will 2Rx4 DDR5 RDIMMs work alongside 1Rx8 or other organizations?
A: Mixing different rank/organization types may be limited by platform rules. Follow your server’s memory population guidelines for best results.

Q: Can I combine this with other DDR5 capacities?
A: Many platforms allow mixed capacities, but optimal performance and interleaving often require matching DIMMs per channel.

Q: Does this DIMM support ECC?
A: Yes. It is a registered ECC module designed for server platforms requiring ECC memory.

Q: What happens if my server does not support 6400 MT/s?
A: The module will clock down to a supported speed defined by the CPU and motherboard.
