Frequently Asked Questions

What is the difference between MTC40F2046S1RC56BG1 and MTC40F2046S1RC56BG1R?
MTC40F2046S1RC56BG1R is the Renesas register component variant while MTC40F2046S1RC56BG1 is the standard variant. Electrical specifications are identical — verify your server QVL for the qualified variant.
What is the difference between MTC40F2046S1RC56BG1 (DDR5-5600) and MTC40F2046S1RC48BA1 (DDR5-4800)?
MTC40F2046S1RC56BG1 runs at DDR5-5600 while MTC40F2046S1RC48BA1 runs at DDR5-4800. 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 MTC40F2046S1RC56BG1 delivers 64GB DDR5-5600 ECC RDIMM in 2Rx4 configuration — the BG1 standard revision for Intel Xeon Scalable and AMD EPYC DDR5-5600 server platforms requiring 64GB per slot.
