FAQs

Q: Is this RDIMM or LRDIMM?
A: It is an LRDIMM. Do not mix with RDIMMs in the same system.

Q: Can I mix different capacities or speeds?
A: Mixing is possible within platform rules, but the memory may run at the lowest common speed; symmetric populations are recommended.

Q: Does this module support ECC?
A: Yes, it is ECC-enabled for enterprise reliability.

Q: What workloads benefit from 128GB LRDIMM?
A: Virtualization hosts, databases, in-memory analytics, and other memory-intensive applications.

Q: Will it clock down with certain CPUs or populations?
A: Yes. Actual memory speed depends on CPU generation and DIMM population per channel.
