FAQs

Q: What is the benefit of dual-rank vs single-rank?
A: Dual-rank modules can improve effective bandwidth on some platforms due to increased bank interleaving, though behavior varies by CPU and memory controller.

Q: Can I mix dual-rank and single-rank DIMMs?
A: Often yes, but follow the server’s memory population rules. Mixing ranks may affect achievable speeds and maximum capacity per channel.

Q: Is this DIMM hot-pluggable?
A: Standard RDIMMs are not hot-pluggable. Power down and follow ESD-safe procedures before installation.

Q: Will ECC work automatically?
A: On platforms that support ECC, error correction is automatic without special OS drivers.

Q: Does this module require pairing?
A: One module can run by itself, but for optimal bandwidth populate memory channels symmetrically per your system guide.
