Frequently Asked Questions

What does the R suffix mean in MTC20C2085S1EC56BD1R?

The R suffix indicates a Renesas component variant. Electrical specifications are identical to MTC20C2085S1EC56BD1 — the difference is the component vendor.

What is the difference between MTC20C2085S1EC56BD1R and MTC20C2085S1EC48BA1?

MTC20C2085S1EC56BD1R runs at DDR5-5600 (PC5-44800) while MTC20C2085S1EC48BA1 runs at DDR5-4800 (PC5-38400). Both are 32GB ECC UDIMM 2Rx8 — choose based on your platform's supported DDR5 speed.

What is the difference between ECC UDIMM and ECC RDIMM in DDR5?

DDR5 ECC UDIMM has no register buffer and suits workstations and entry-level servers. DDR5 ECC RDIMM includes a register buffer required by most enterprise server platforms for higher DIMM counts and signal integrity.

The Micron MTC20C2085S1EC56BD1R delivers 32GB DDR5-5600 ECC UDIMM in 2Rx8 configuration with Renesas component — the BD1R variant for workstations and entry-level servers supporting ECC UDIMM DDR5-5600.
