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.

Kingston FURY Renegade RGB 32GB (2x16GB) DDR5-7200 CL38 on Amazon (opens in a new tab)
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 timing is a problem.
Why we like it
On CAS latency it sits mid-pack at CL38: the Trident Z5 Royal 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 Trident Z5 Royal, 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 second of 5, between the cheaper Delta RGB 6400 and the pricier Delta RGB 7200, at the time of writing.
Key dimensions & specs

Kingston FURY Beast 64GB (2x32GB) DDR5-6400 CL32 on Amazon (opens in a new tab)
FURY Beast 64GB offers 6400MT/s at CL32 with an EXPO profile across two 32GB sticks.
Best for
- Buyers who put capacity first.
Skip if
- Skip it if rated speed matters most to you; the FURY Renegade 7200 offers 7200MT/s.
Why we like it
On CAS latency it ties with the Trident Z5 Royal at CL32. On rated speed it ties with the Delta RGB 6400 and the Trident Z5 Royal at 6400MT/s. On capacity it leads this guide at 64GB (2 sticks), ahead of the FURY Renegade 7200 (32GB (2 sticks)).

It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots. It was the most expensive pick when we checked, so weigh what it adds over the Trident Z5 Royal. If rated speed is your priority, the FURY Renegade 7200 (7200MT/s) is the stronger choice.
Key dimensions & specs
- CAS latency: CL32
- Rated speed: 6400MT/s
- Capacity: 64GB (2 sticks)
- Profiles: EXPO
- Memory type: DDR5
Pros
- 64GB for heavy multitasking and creative work

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Profiles
- We checked for AMD EXPO and Intel XMP support.
- Capacity
- We focused on two-stick 32GB and 64GB kits.
- Fit
- We noted RGB and low-profile heatspreaders where listed.
- Speed and timings
- We compared listed speed and CAS latency.
What to Look for in a High-Speed RAM
Key buying criteria so you get the right fit the first time.
Where these picks differ: CAS latency
Among these picks, CAS latency runs from CL40 on the Delta RGB 6400 to CL32 on the Trident Z5 Royal. Pick the lowest figure that covers your use; the extra usually costs more than it returns.
DDR5-6000 is the AM5 sweet spot
AMD's Ryzen 7000 and 9000 chips run memory in sync up to about 6000MT/s. Faster kits often fall out of that sync and gain little.
Intel Core Ultra chips handle higher speeds more comfortably.
32GB is the gaming default
32GB covers games with browsers and chat running. 64GB suits video editing, large projects and heavy multitasking.
Check for EXPO or XMP
EXPO profiles set speed and timings in one click on AMD boards; XMP does the same on Intel. Many kits carry both.
Buy one two-stick kit
Two sticks run faster and more reliably than four on DDR5. Buy the capacity you need in one matched kit.

Frequently Asked Questions
Which pick leads on rated speed?
The FURY Renegade 7200 leads at 7200MT/s, ahead of the Delta RGB 7200 at 7200MT/s; the FURY Beast 64GB sits at the other end with 6400MT/s.
Which pick costs the least here?
Start with the Delta RGB 6400, the lowest-priced pick when we checked. The FURY Beast 64GB is the premium end, so the spread between them shows what extra money buys here.
Is DDR5-8000 worth it?
On AM5, rarely; it often runs out of sync with the memory controller. It suits Intel builds tuned for high speeds.
Can I mix two kits?
It often fails to run at rated speed. Buy one kit with all the capacity you need.
Why does a new DDR5 system take long to boot the first time?
The board trains the memory on first boot, which can take a minute or more. Let it finish.
Bottom Line
Our first pick is the FURY Renegade 7200, chosen for Kingston's infrared RGB syncing. Look at the Delta RGB 7200 for SK Hynix A-die memory, the Delta RGB 6400 for undercutting the FURY Renegade 7200 on price when we checked and the Trident Z5 Royal for timings of 32-39-39-102 if those matter more to you.
