Frequently Asked Questions

What is the difference between MTC40F2046S1RC48BA1 and MTC40F2046S1RC48BA1R?

MTC40F2046S1RC48BA1R is the Renesas register component variant while MTC40F2046S1RC48BA1 is the standard base revision. Electrical specifications are identical — verify your server QVL for the qualified variant.

What is the difference between MTC40F2046S1RC48BA1 (DDR5-4800) and MTC40F2046S1RC56BG1 (DDR5-5600)?

MTC40F2046S1RC48BA1 runs at DDR5-4800 while MTC40F2046S1RC56BG1 runs at DDR5-5600. Both are 64GB 2Rx4 ECC RDIMM — choose based on your server”s supported DDR5 speed.

What does 2Rx4 mean?

Dual Rank x4 — two ranks of x4 (4-bit wide) DRAM devices providing high capacity and bandwidth per DIMM slot.

The Micron MTC40F2046S1RC48BA1 delivers 64GB DDR5-4800 ECC RDIMM in 2Rx4 configuration — the BA1 standard base revision for Intel Xeon Scalable and AMD EPYC DDR5-4800 server platforms requiring 64GB per slot.
