FAQs

Q: Does my platform support 256GB RDIMMs?
A: Check your server/CPU memory QVL; not all platforms support 256GB per-DIMM density or 8Rx4 rank.

Q: Can I mix with lower-capacity DDR5 RDIMMs?
A: Yes, but match type (RDIMM) and aim for symmetric channel population for best results.

Q: Is this ECC memory?
A: Yes, ECC Registered (RDIMM) with DDR5 on-die ECC.

Q: Will this work in a desktop motherboard?
A: No, RDIMMs require server/workstation boards that support registered memory.

Q: What is 8Rx4?
A: Eight ranks of x4 DRAM enabling very high capacity per DIMM; platform support is required.
