The Best High-Speed RAM
Five memory kits compared, from the Delta RGB 6400 to the FURY Beast 64GB, with the trade-offs of each named.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated

Kits at 6,400MT/s and above help memory-sensitive work, if the CPU and board can run them. Every pick is rated at 6,400MT/s or faster, ordered by speed.
We sorted these picks by CAS latency, rated speed and capacity, working from the makers' own data; if a maker skips profiles, the guide says so, and no figure here comes from our own testing.

Also Consider1 of 5
Kingston FURY Renegade RGB 32GB (2x16GB) DDR5-7200 CL38
FURY Renegade 7200 offers 7200MT/s at CL38 with XMP, for Intel boards that support high memory speeds.
Best for
- Buyers who want Kingston's infrared RGB syncing.
Skip if
- Worth skipping when xMP profile only, so AM5 boards may need manual timings is a problem.
Why we like it
On CAS latency it sits mid-pack at CL38: the FURY Renegade White offers CL32, and the Delta RGB 6400 comes in at CL40. On rated speed it ties with the Delta RGB 7200 at 7200MT/s. Like the Delta RGB 7200 and FURY Renegade White, it has XMP profiles, while the FURY Beast 64GB uses EXPO profiles.
It also comes with Kingston's infrared RGB syncing. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots.
RGB heatspreaders are taller than plain ones, so check the clearance under a large tower cooler. On price it sat third of 5, between the cheaper FURY Renegade White and the pricier Delta RGB 7200, at the time of writing.

How We Chose
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

- How these picks were ranked
- We compared five kits on CAS latency, rated speed, capacity and profiles, using each maker's published specs. These are research figures, not bench results: 1 of 5 picks leave out profiles.
- The shared baseline
- All 5, from the FURY Renegade 7200 to the FURY Beast 64GB, state CAS latency, rated speed and capacity and share DDR5 memory type.
- Where the specs have gaps
- The Delta RGB 6400 gives no profiles; the FURY Beast 64GB gives no RGB.
- Price range
- At our last check the picks ran from the Delta RGB 6400 ($500 to $1000) to the FURY Beast 64GB ($1000 to $1500).
