NEMIX DDR5-5600 ECC RDIMM 1x128GB vs NEMIX DDR5-6400 ECC RDIMM 1x128GB in detail
True latency
NEMIX DDR5-6400 ECC RDIMM 1x128GB is the lower-latency kit at 16.25 ns, against 16.43 ns for NEMIX DDR5-5600 ECC RDIMM 1x128GB — a difference of 0.18 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. NEMIX DDR5-5600 ECC RDIMM 1x128GB runs 5600 MT/s at CL46; NEMIX DDR5-6400 ECC RDIMM 1x128GB runs 6400 MT/s at CL52.
Transfer rate
NEMIX DDR5-6400 ECC RDIMM 1x128GB is rated 6400 MT/s against 5600 MT/s for NEMIX DDR5-5600 ECC RDIMM 1x128GB — 51200 MB/s per module, against 44800 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
NEMIX DDR5-5600 ECC RDIMM 1x128GB ships as 1 × 128GB and NEMIX DDR5-6400 ECC RDIMM 1x128GB ships as 1 × 128GB — the same number of sticks either way, so both populate a board's slots identically.
Lighting and ECC
On the lighting question: NEMIX DDR5-5600 ECC RDIMM 1x128GB does not have RGB lighting, and NEMIX DDR5-6400 ECC RDIMM 1x128GB does not have RGB lighting. On error correction: NEMIX DDR5-5600 ECC RDIMM 1x128GB is published with ECC support, and NEMIX DDR5-6400 ECC RDIMM 1x128GB 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
At least one of these kits has no tracked price right now, so this page has no buying answer to give: which is worth more depends on what each costs, and that is exactly what is missing. On specifications alone, NEMIX DDR5-6400 ECC RDIMM 1x128GB has the lower true latency at 16.25 ns.
Common questions about this pair
- Is NEMIX DDR5-5600 ECC RDIMM 1x128GB faster than NEMIX DDR5-6400 ECC RDIMM 1x128GB?
- NEMIX DDR5-6400 ECC RDIMM 1x128GB is, on true latency: 16.25 ns against 16.43 ns. NEMIX DDR5-5600 ECC RDIMM 1x128GB runs 5600 MT/s at CL46 and NEMIX DDR5-6400 ECC RDIMM 1x128GB runs 6400 MT/s at CL52; the CAS numbers alone do not settle it, because they count clock cycles rather than time.
