Micron DDR5-5600 ECC RDIMM 1x32GB vs NEMIX DDR5-6400 ECC RDIMM 1x32GB in detail

True latency

NEMIX DDR5-6400 ECC RDIMM 1x32GB is the lower-latency kit at 16.25 ns against 16.43 ns for Micron DDR5-5600 ECC RDIMM 1x32GB, 0.18 ns between them. That is the figure that reconciles the two spec sheets: a CAS number counts cycles, and cycles mean nothing apart from the rate they are counted at. Micron DDR5-5600 ECC RDIMM 1x32GB runs 5600 MT/s at CL46; NEMIX DDR5-6400 ECC RDIMM 1x32GB runs 6400 MT/s at CL52.

Transfer rate

NEMIX DDR5-6400 ECC RDIMM 1x32GB carries the higher rating, 6400 MT/s to 5600 MT/s for Micron DDR5-5600 ECC RDIMM 1x32GB — 51200 MB/s per module against 44800 MB/s. That is peak transfer rate, not access time: a higher clock is reached by counting more cycles for each access, which is why the CAS numbers differ too and why the true latency above is the directly comparable figure.

Price and tracked history

Micron DDR5-5600 ECC RDIMM 1x32GB is tracked at $1,999.00, or $62.47 per gigabyte; NEMIX DDR5-6400 ECC RDIMM 1x32GB at $1,446.74, or $45.21. At the same 32GB, that puts NEMIX DDR5-6400 ECC RDIMM 1x32GB $552.26 less than Micron DDR5-5600 ECC RDIMM 1x32GB. NEMIX DDR5-6400 ECC RDIMM 1x32GB's $1,446.74 sits 38% under its own 90-day median.

Kit layout

Micron DDR5-5600 ECC RDIMM 1x32GB ships as 1 × 32GB and NEMIX DDR5-6400 ECC RDIMM 1x32GB ships as 1 × 32GB — the same number of sticks on both sides, so they populate a board's slots the same way.

Lighting and ECC

On lighting: Micron DDR5-5600 ECC RDIMM 1x32GB is published with no RGB lighting, and NEMIX DDR5-6400 ECC RDIMM 1x32GB is published with no RGB lighting. On error correction: Micron DDR5-5600 ECC RDIMM 1x32GB supports ECC, and NEMIX DDR5-6400 ECC RDIMM 1x32GB supports ECC. ECC is a board and CPU feature as much as a module one, so it is worth having only where the platform can use it.

Which to buy

Both axes this page measures point to NEMIX DDR5-6400 ECC RDIMM 1x32GB: 16.25 ns of true latency against 16.43 ns, and the lower of the two tracked prices.
