Frequently Asked Questions

What is the difference between MTC20F2085S1RC64BH1 and MTC40F2046S1RC64BH1?
Both are 64GB DDR5-6400 ECC RDIMM 2Rx4. MTC20F and MTC40F indicate different module PCB/component configurations — verify your server QVL to confirm which variant is qualified for your platform.
What is the difference between DDR5-6400 and DDR5-5600?
DDR5-6400 (PC5-51200) provides approximately 14% higher bandwidth than DDR5-5600 (PC5-44800). DDR5-6400 requires server platform support — verify your server's maximum supported DDR5 speed.
What does 2Rx4 mean?
Dual Rank x4 — two ranks of x4 (4-bit wide) DRAM devices providing higher capacity and bandwidth per DIMM.

The Micron MTC20F2085S1RC64BH1 delivers 64GB DDR5-6400 ECC RDIMM in 2Rx4 configuration for Intel Xeon Scalable and AMD EPYC DDR5-6400 server platforms requiring maximum bandwidth at 64GB per slot.
