Overview
Micron MTC20F2085S1RC48BA1 is a 32GB DDR5 registered DIMM rated at 4800 MT/s (PC5-38400) with CL40 timing. It is dual rank, runs at 1.1V and includes ECC. The MTC20 prefix indicates 20 DRAM packages, which on a dual-rank DDR5 ECC module matches x8 devices (2Rx8).
DDR5-4800 was the launch speed for the first DDR5 server platforms, such as 4th Gen Xeon Scalable and AMD EPYC 9004, so this module fits the memory profile of many servers built from 2023 onward. Like all DDR5 RDIMMs, it has an on-module power management chip and two independent subchannels per module, and it does not fit DDR4 slots. On a newer processor that supports faster memory, it still runs at 4800 MT/s.
Before ordering:
- Match the x8 organization of the memory already installed. Many server makers do not support mixing x4 and x8 DDR5 modules.
- Avoid mixing speeds: when 4800 and 5600 modules share a server, memory generally runs at the slower rate.
- An R-suffixed version (MTC20F2085S1RC48BA1R) is also sold; ask us which label your quote covers.
- If OEM support matters, check whether your server maker requires its own part number.
We have not found a manufacturer or server-OEM source listing specific supported servers, so none are published here. A 32GB module per channel is a common baseline for general-purpose DDR5 servers. ICT Devices can quote single modules or full sets; send us your server model and installed memory.

Frequently asked questions
Is MTC20F2085S1RC48BA1 x4 or x8?
It is dual rank with x8 DRAM (2Rx8), consistent with its 20-package layout.
What is the difference from MTC20F2085S1RC48BA1R?
Resellers sell both labels as the same 32GB dual-rank DDR5-4800 RDIMM. Micron has not published the meaning of the R suffix in any source we could reach, so tell us if you need one exact label.
Can I install it with DDR5-5600 memory?
Mixed speeds generally run at the slower rate, and many servers restrict mixing module types. Use matching modules where possible.
