The fastest of NEMIX's three RDIMM speed grades runs at 6400, rated CL52 — the third timing bin in the same server lineup alongside the CL40 (4800) and CL46 (5600) kits, with no other CAS option sold at this speed.
This 2×64GB configuration is 128GB, rated 6400 MT/s CL52. Capacity again spans 16GB up to a 128GB four-module kit, the same range covered at the other two speeds in NEMIX's RDIMM lineup, so it's the module count rather than the total that changes most between listings.
Like the rest of that lineup, this is registered ECC RDIMM DDR5 for server boards, not a substitute for unbuffered consumer memory in a standard desktop system.
Crucial Pro trades looks for a compatibility-first, overclocking-headroom pitch, and within this 6400 MT/s grade, CAS latency -- not the shared headline speed -- is the number that actually separates one listing from another.
FURY Beast at 6000 spans three CL grades under one name plus a four-module 64GB option its 5600 sibling doesn't offer, which makes matching the exact SKU more important here than with most families.
DDR5 doubled the bandwidth and moved power regulation onto the module. Whether that is worth paying for depends entirely on which platform you are building.
Flare X5 is a heatspreader-only DDR5-6000 line built for clearance-constrained builds, and within this 6000 MT/s grade every listing shares that one headline speed — the CL bin and capacity are the only things actually separating listings.
16 GB is no longer comfortable, 32 GB is the sensible default, and 64 GB is a workload decision rather than a future-proofing one.
CAMM2 and SODIMM are physically incompatible laptop memory formats. The difference is not speed at a given rating but how many channels each module carries, how the module attaches, and whether a machine can ever add memory rather than replace it.
