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 Alex Morgan, PC Hardware Editor
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
Flare X5 16GB offers 5600MT/s at CL36 and 1.20V with EXPO, in a low-profile design.
Best for
- Keeping the cost under $500.
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
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.

Tightest CAS Latency4 of 5
Patriot Viper Elite 5 RGB 32GB (2x16GB) DDR5-6000 CL30
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).
On capacity it ties with the Crucial Pro 6400 White and the Delta RGB White at 32GB (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 Crucial Pro 6400 White and cheaper picks cost less, and the Delta RGB White cost more.

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, since the Flare X5 16GB costs less.
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)).
It also comes with one of the lowest prices among the white kits. 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. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the Viper Elite 5 RGB and the rest.

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.

- What we compared
- We set side by side five kits on CAS latency, rated speed, capacity and profiles from manufacturer specifications. We did not test them in-house, and CAS latency and RGB are missing for at least one pick.
- The shared baseline
- All 5, from the Flare X5 16GB to the Delta RGB White, state rated speed, capacity and profiles and share DDR5 memory type.
- Where the specs have gaps
- The Vengeance RGB RS 16GB gives no CAS latency; the Flare X5 16GB and the Crucial Pro 6400 White give no RGB.
- Price range
- From the Flare X5 16GB to the Delta RGB White, all sat in the $250 to $500 tier when we checked.
What to Look for in an RAM for AM5
Key buying criteria so you get the right fit the first time.
Rated speed across these picks
Across these 5 picks rated speed spans 5600MT/s (the Flare X5 16GB) to 6400MT/s (the Crucial Pro 6400 White). For less, the Vengeance RGB RS 16GB is the runner-up at 6000MT/s.
Capacity
Here capacity runs from 16GB (2 sticks) on the Vengeance RGB RS 16GB to 32GB (2 sticks) on the Crucial Pro 6400 White, a 100% spread. If capacity is your first filter, the Crucial Pro 6400 White sets the ceiling at 32GB (2 sticks).

Memory modules installed in a motherboard's DIMM slots How much CAS latency you need
Here CAS latency runs from CL38 on the Delta RGB White to CL30 on the Viper Elite 5 RGB, a 21% spread. For less, the Crucial Pro 6400 White is the runner-up at CL32. The Vengeance RGB RS 16GB gives no CAS latency figure, so 4 of 5 picks are compared here.
RGB
The Vengeance RGB RS 16GB, the Viper Elite 5 RGB and the Delta RGB White have it.
Features beyond the spec table
The Crucial Pro 6400 White: a white heatspreader without lighting. The Viper Elite 5 RGB: RGB lighting on a 6000MT/s CL30 kit. The Delta RGB White: one of the lowest prices among the white kits.

Frequently Asked Questions
Is the Crucial Pro 6400 White ahead of the Vengeance RGB RS 16GB on rated speed?
The Crucial Pro 6400 White leads at 6400MT/s, with the Vengeance RGB RS 16GB at 6000MT/s. The Flare X5 16GB is at the other end of this group with 5600MT/s.
Which has the tightest CAS latency: the Viper Elite 5 RGB or the Crucial Pro 6400 White?
The Viper Elite 5 RGB is lowest on CAS latency at CL30; the Crucial Pro 6400 White follows at CL32, 6% apart. The Delta RGB White closes the ranking at CL38. The Vengeance RGB RS 16GB doesn't state a CAS latency figure, so it sits outside this comparison; 4 of 5 picks are ranked.
Is the Delta RGB White worth paying more than the Flare X5 16GB?
On paper it adds rated speed (6000MT/s against 5600MT/s) and capacity (32GB (2 sticks) against 16GB (2 sticks)). It does not win everywhere: the Flare X5 16GB still leads on CAS latency (CL36). Both sat in the $250 to $500 tier when we checked, so the gains in rated speed and capacity cost little extra by tier.
What makes the Flare X5 16GB the Lowest Price Here?
It carries the badge for the cheapest way into this group, below the Vengeance RGB RS 16GB. It makes sense for keeping the cost under $500.
Do the Flare X5 16GB and the Vengeance RGB RS 16GB differ on profiles?
The Flare X5 16GB uses EXPO; the Vengeance RGB RS 16GB, the Crucial Pro 6400 White, the Viper Elite 5 RGB and the Delta RGB White use EXPO and XMP.
Beyond the specs, what sets the Flare X5 16GB and the Vengeance RGB RS 16GB apart?
The Flare X5 16GB: a 1.20V rating. The Vengeance RGB RS 16GB: iCUE lighting control. The Crucial Pro 6400 White: Micron memory from Crucial's parent company.
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.
