16GB DDR5-6400 ECC RDIMM

This 16GB registered DDR5 module targets servers and workstations that require error-correcting memory. It replaces specific Micron part numbers including MTC10F1084S1RC64BA1, MTC10F1084S1RC64BD1 and MTC10F1084S1RC64BD2. The single-rank 1Rx8 design uses Micron DRAM ICs and operates at the standard 1.10V.

DDR5 RDIMM platform constraints

DDR5 RDIMMs only function in motherboards built for registered DDR5 memory with 288-pin slots. The registered buffer adds one clock cycle of latency and the module will not work in consumer boards that expect unbuffered DIMMs. Verify your system manual for supported speeds, channel population rules and maximum capacity per slot.

1Rx8 rank and ECC decide fit

The 1Rx8 organisation with on-die ECC determines whether this module matches your server's memory controller requirements. Dual-rank or x4 configurations behave differently and may not be interchangeable in the same channel. Confirm the exact rank and ECC type before ordering.

Questions about this item

Should I choose the 16GB module or add a second stick for 32GB total?

Each module is 16GB; adding a second identical stick gives 32GB in dual-channel if your board supports it.

What does the 6400MHz rating deliver in a live server?

The module runs at DDR5 6400 (PC5-51200) with CL32 latency at 1.1V, providing high throughput for registered ECC workloads.

How does the 288-pin RDIMM interface limit real-world speed?

The 288-pin DDR5 RDIMM slot caps operation to the JEDEC 6400MT/s standard; the registered buffer adds one cycle but ensures signal integrity at that rate.
