Dominator Titanium RGB sits alongside Vengeance in Corsair's DDR5 range, sold under a 6600 name that also covers 5600- and 6000-rated kits at looser CL30/CL36 timings.
The 2×16GB kit here totals 32GB, rated 5600 MT/s CL36. Configurations run from two-module 32GB kits to four-module sets as large as 96GB, and because several speed and CL combinations share one product name, the figure on the specific listing — not the "6600" in the title — is what to check against a board's supported speeds.
Every kit in this line carries RGB lighting, and all of it is unbuffered DDR5 UDIMM for desktop platforms.
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.
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.
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.
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.
Capacity avoids stutter caused by running out of memory; speed affects how efficiently the CPU feeds data to the GPU. They solve different problems, and buying enough of the first one before spending on the second is the right order.
