Micron 32GB DDR5 5600MT/s PC5-44800 CL46 ECC UDIMM - MTC20C2085S1EC56BG1R

The Micron MTC20C2085S1EC56BG1R is a 32GB DDR5 5600MT/s (PC5-44800) ECC Unbuffered DIMM (UDIMM) with CL46 latency. Unlike registered DIMMs, UDIMMs connect directly to the memory controller — making them suitable for workstations and entry-level servers supporting ECC UDIMM. DDR5 delivers significantly higher bandwidth and improved power efficiency compared to DDR4, while ECC ensures data integrity for professional workloads.

Frequently Asked Questions

What is the difference between ECC UDIMM and ECC RDIMM?

ECC UDIMM connects directly to the memory controller without a register buffer — suitable for workstations and entry-level servers. ECC RDIMM uses a register buffer for signal integrity, enabling more DIMMs per channel in high-capacity server configurations.

Is DDR5 ECC UDIMM compatible with consumer motherboards?

Most consumer DDR5 motherboards do not support ECC. ECC UDIMM DDR5 requires a platform that explicitly supports ECC — such as Intel Xeon W or AMD Ryzen Pro with ECC support.

What is the benefit of DDR5 over DDR4 for ECC workloads?

DDR5 provides significantly higher bandwidth (up to 2x DDR4), lower operating voltage (1.1V vs 1.2V), and on-die ECC in addition to system-level ECC — improving both performance and reliability.
