Frequently Asked Questions

Is ECC UDIMM the same as RDIMM?

No — ECC UDIMM is unbuffered and used in workstations and select consumer platforms. RDIMM (Registered DIMM) uses a register buffer and is designed for server platforms. They are not interchangeable.

Does the Ryzen 9000 series support ECC UDIMM?

AMD Ryzen 7000/9000 processors support ECC UDIMM at the CPU level, but actual ECC functionality depends on motherboard firmware support. Check your specific board's QVL.

What does BD1 die revision mean?

BD1 refers to Micron's internal die revision identifier for this DDR5 module, indicating the specific DRAM die used — relevant for overclocking compatibility and QVL matching.

The Micron MTC20F2085S1RC64BD1 is purpose-engineered for professionals who need the speed of DDR5-6400 with the reliability of ECC error correction — a combination that makes it well-suited for mission-critical workstation and compute-intensive deployments.
