The Best RAM for AM5
Five memory kits compared, from the Flare X5 16GB to the Delta RGB White, with the trade-offs of each named.
By The PC Journal editorial team
12 min read5 products evaluated
AM5 Ryzen chips run best with DDR5-6000 and an AMD EXPO profile. Every pick is DDR5 with EXPO support, ordered from the lowest price.
Our comparison rests on published figures for CAS latency, rated speed and capacity; where a maker leaves out CAS latency, we say so, and no figure here comes from our own testing.

Our Picks
Lowest Price Here1 of 5
G.SKILL Flare X5 16GB (2x8GB) DDR5-5600 CL36 on Amazon (opens in a new tab)
Flare X5 16GB offers 5600MT/s at CL36 and 1.20V with EXPO, in a low-profile design.
Best for
- Keeping the budget tight.
Skip if
- Skip it if rated speed matters most to you; the Crucial Pro 6400 White offers 6400MT/s.
Why we like it
On CAS latency it sits mid-pack at CL36: the Viper Elite 5 RGB offers CL30, and the Delta RGB White comes in at CL38. On rated speed it trails the group at 5600MT/s, while the Crucial Pro 6400 White offers 6400MT/s. It matches the Vengeance RGB RS 16GB on capacity (16GB (2 sticks)).
No other pick in this guide offers EXPO profiles; compare the Viper Elite 5 RGB, which has EXPO and XMP profiles. It also comes with a 1.20V rating and timings of 36-36-36-89. 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. It undercut the Vengeance RGB RS 16GB and every other pick on price at the time of writing.

Also Consider2 of 5
CORSAIR Vengeance RGB RS 16GB (2x8GB) DDR5-6000 on Amazon (opens in a new tab)
Vengeance RGB RS 16GB offers 6000MT/s with both EXPO and XMP profiles and iCUE lighting.
Best for
- Buyers who want iCUE lighting control.
Skip if
- Skip it if you need to know its CAS latency before buying; the maker doesn't publish one.
Why we like it
It matches the Viper Elite 5 RGB and the Delta RGB White on rated speed (6000MT/s). On capacity it ties with the Flare X5 16GB at 16GB (2 sticks). 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. When we checked, only the Flare X5 16GB cost less, and the Crucial Pro 6400 White cost more. If you want a confirmed CAS latency, look to the Viper Elite 5 RGB instead: it offers CL30, while this one gives no figure.

The Viper Elite 5 RGB is a 6000 CL30 kit with EXPO and XMP.
Best for
- Buyers who put CAS latency first.
Skip if
- Price-first buyers should look at the Flare X5 16GB, which cost less when we checked.
Why we like it
It is a straightforward, lower-cost RGB option. Nothing else here matches its CL30 CAS latency; the Crucial Pro 6400 White comes closest at CL32. It matches the Vengeance RGB RS 16GB and the Delta RGB White on rated speed (6000MT/s).

Delta RGB White offers 6000MT/s at CL38 with both profiles and a wide lightbar at a low white-kit price.
Best for
- Buyers for whom price is not the deciding factor.
Skip if
- Skip it if CAS latency matters most to you; the Viper Elite 5 RGB offers CL30.
Why we like it
On CAS latency it trails the group at CL38, while the Viper Elite 5 RGB offers CL30. On rated speed it ties with the Vengeance RGB RS 16GB and the Viper Elite 5 RGB at 6000MT/s. It matches the Crucial Pro 6400 White and the Viper Elite 5 RGB on capacity (32GB (2 sticks)).

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Fit
- We noted RGB and low-profile heatspreaders where listed.
- Profiles
- We checked for AMD EXPO and Intel XMP support.
- Speed and timings
- We compared listed speed and CAS latency.
- Capacity
- We focused on two-stick 32GB and 64GB kits.
What to Look for in an RAM for AM5
Key buying criteria so you get the right fit the first time.
How much CAS latency you need
Among these picks, CAS latency runs from CL38 on the Delta RGB White to CL30 on the Viper Elite 5 RGB. 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.
Intel chips take faster kits
13th and 14th Gen Core chips handle 6400MT/s and faster DDR5 more readily than AM5, especially on Z790 boards. Check the board's memory support list above 6400MT/s.

Frequently Asked Questions
How do these memory kits compare on capacity?
The Crucial Pro 6400 White leads at 32GB (2 sticks), ahead of the Viper Elite 5 RGB at 32GB (2 sticks); the Vengeance RGB RS 16GB sits at the other end with 16GB (2 sticks).
Which is the cheapest pick in this guide?
The Flare X5 16GB. It undercut the Vengeance RGB RS 16GB when we checked, while the Delta RGB White cost the most of the group.
Can I mix two kits?
It often fails to run at rated speed. Buy one kit with all the capacity you need.
What happens if I don't enable EXPO or XMP?
The kit runs at a slower default speed. Enable the profile in the BIOS to get the rated speed.
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.
Bottom Line
Our first pick is the Flare X5 16GB, chosen for the cheapest way into this group, below the Vengeance RGB RS 16GB. Look at the Vengeance RGB RS 16GB for iCUE lighting control, the Crucial Pro 6400 White for the fastest rated speed here (6400MT/s) and the Viper Elite 5 RGB for the tightest CAS latency here (CL30) if those matter more to you.
DDR5-6000 is AM5's sweet spot; faster kits rarely help.
