Micron DDR5-4800 ECC RDIMM 1x32GB vs NEMIX DDR5-5600 ECC RDIMM 2x16GB in detail

True latency

NEMIX DDR5-5600 ECC RDIMM 2x16GB is the lower-latency kit at 16.43 ns, against 16.67 ns for Micron DDR5-4800 ECC RDIMM 1x32GB — a difference of 0.24 ns. That figure is what reconciles the two spec sheets: CAS latency counts clock cycles, so it only means something next to the clock it counts. Micron DDR5-4800 ECC RDIMM 1x32GB runs 4800 MT/s at CL40; NEMIX DDR5-5600 ECC RDIMM 2x16GB runs 5600 MT/s at CL46.

Transfer rate

NEMIX DDR5-5600 ECC RDIMM 2x16GB is rated 5600 MT/s against 4800 MT/s for Micron DDR5-4800 ECC RDIMM 1x32GB — 44800 MB/s per module, against 38400 MB/s. That is peak transfer rate, not access time: reaching a higher clock costs more cycles on each access, which is why the CAS numbers differ too, and why the true latency above is the figure that compares directly.

Kit layout

Micron DDR5-4800 ECC RDIMM 1x32GB ships as 1 × 32GB, NEMIX DDR5-5600 ECC RDIMM 2x16GB ships as 2 × 16GB. That is a real difference and not a ranking: more sticks fill more channels on a board that has them, while fewer sticks leave slots free for a later addition. Which suits depends on the board and on whether more memory is planned.

Lighting and ECC

On the lighting question: Micron DDR5-4800 ECC RDIMM 1x32GB does not have RGB lighting, and NEMIX DDR5-5600 ECC RDIMM 2x16GB does not have RGB lighting. On error correction: Micron DDR5-4800 ECC RDIMM 1x32GB is published with ECC support, and NEMIX DDR5-5600 ECC RDIMM 2x16GB is published with ECC support. Whether ECC is worth having depends on the platform as much as the modules — the board and the CPU have to support it too.

Which to buy

Without a tracked price for both, this page cannot say which to buy — the answer depends on cost, and cost is what is absent. What the specifications do say is that NEMIX DDR5-5600 ECC RDIMM 2x16GB has the lower true latency, 16.43 ns.

Common questions about this pair

Is Micron DDR5-4800 ECC RDIMM 1x32GB faster than NEMIX DDR5-5600 ECC RDIMM 2x16GB?
NEMIX DDR5-5600 ECC RDIMM 2x16GB is, on true latency: 16.43 ns against 16.67 ns. Micron DDR5-4800 ECC RDIMM 1x32GB runs 4800 MT/s at CL40 and NEMIX DDR5-5600 ECC RDIMM 2x16GB runs 5600 MT/s at CL46; the CAS numbers alone do not settle it, because they count clock cycles rather than time.
