Micron 64GB DDR5-5600 ECC RDIMM 2Rx4 — MTC40F2046S1RC56BD1

The Micron MTC40F2046S1RC56BD1 is a 64GB DDR5-5600 ECC Registered DIMM (RDIMM) in 288-pin form factor operating at 5600MHz (PC5-44800) with CL46 latency at 1.1V. Configured as Dual Rank x4 it delivers high-capacity ECC-protected server memory for 5th Gen Intel Xeon Scalable and AMD EPYC platforms requiring 64GB per slot at DDR5-5600 speeds.

Key Features

  • 64GB capacity — DDR5-5600 ECC RDIMM for high-density server memory
  • DDR5-5600 (PC5-44800) — high-speed DDR5 server memory
  • ECC Registered — error correction and registered buffer for server reliability
  • Dual Rank x4 (2Rx4) — high-density x4 die configuration
  • CL46 latency at 1.1V
  • 288-pin DIMM — standard server memory form factor
  • Micron genuine server memory

Frequently Asked Questions

What is the difference between MTC40F2046S1RC56BD1 and MTC40F2046S1RC56BD1R?
The R suffix in MTC40F2046S1RC56BD1R indicates a Renesas register component variant. Both modules have identical electrical specifications — the difference is the register chip vendor used in manufacturing.
What is the difference between MTC40F2046S1RC56BD1 and MTC40F2046S1RC64BH1?
MTC40F2046S1RC56BD1 runs at DDR5-5600 (PC5-44800) while MTC40F2046S1RC64BH1 runs at DDR5-6400 (PC5-51200). Both are 64GB 2Rx4 ECC RDIMMs.
What does 2Rx4 mean?
2Rx4 means Dual Rank x4 — the DIMM has two ranks of memory chips with x4 (4-bit wide) DRAM devices allowing higher capacity per DIMM.

The Micron MTC40F2046S1RC56BD1 delivers 64GB of DDR5-5600 ECC registered server memory in 2Rx4 configuration — purpose-built for Intel Xeon Scalable and AMD EPYC DDR5 server platforms requiring high-density 64GB per slot at DDR5-5600 speeds.

Frequently Asked Questions

Why do I see an incorrect image for this item?

Product images are meant for illustrative purposes alone, and you may not always see the original image.

What do you mean by term Refurbished?

Refurbished means a used computer part or device that has been cleaned, checked, and repaired to make sure it works properly again. Unlike regular second-hand items, refurbished products go through testing and fixing so they can perform like new.

How many days does it take to ship goods to customers?

All orders are processed within 1-2 business days. Orders placed on weekends or public holidays will be processed on the next business day. For more info visit shipping policy.

What is your return policy?

Our Return Policy comprises a 30-day warranty for Refurbished products. There will be a restocking fee applied when you return non-defective returns. For further details, kindly take a look at our Return Policy page.

Do you deliver my ordered items in their original retail box?

For Brand New items, you will receive them in their original retail box. For Refurbished items, you will receive them in a Brown Box or Bulk Packaging.

Do your printers come with ink cartridges?

Refurbished printers do not come with ink cartridges or toners.
