1. G.SKILL Trident Z Royal F4-4000C15D-16GTRS
Best High-Speed RAM For Ryzen 5900X/5950X
- Trident Z Royal Silver Edition - with RGB
- 3200MHz memory speed, PC4-25600, CL16
- Two matched 8GB DDR4 modules, 288 pins, Voltage 1.35V
The best high-end RAM for Ryzen 5900x and 5950x right now is G.Skill’s Trident Z Royal is F4-4000C15D.
It comes with a clock speed of 4000MHz, CAS Latency of CL15, and has 15-16-16-36 timings.
As far as the aesthetics go, you would find it hard not to admire these sticks. They come with gold-colored aluminum heat spreaders. Some companies, to dissipate heat quickly, make the spreaders overly large.
Although keeping the temperatures lower, their large profile creates some compatibility issues in SFF builds. Thankfully, this is not the case here, as G.Skill has kept the size within the check.
To control the RGB lighting, these sticks come with G. Skill’s Lighting control software. Using this app, you can control eight LEDs on each of the modules. Not only that, you can change the brightness level as well. Since these sticks get power from the DIMM slots, there’s no extra wiring for the RGB.
Despite coming in with 4000 MHz speed out of the box, there is some headroom for overclocking (thanks to Samsung B-Die IC), and you can go to even 4266 MHz. But still, we recommend it to keep it at the factory speed to avoid any stability issue that may arise in the long term.
In terms of performance, we got mixed results.
What does it mean?
Well, some apps benefited from this higher speed memory, such as Handbrake, while others barely showed any improvement. The same is the case in gaming, where some games like Metro: Exodus and Shadow of the Tomb Raider showed noticeable FPS improvement with this RAM while others, such as Battlefield V, perform just as they would with slightly lower RAMs.
So if you’re a little tight on budget, it would be better to look at other options from this roundup.
But if you want to complement your 5900X/5950X with premium and overclockable RAM sticks, F4-4000C15D is a perfect option.
- Premium design
- Overclocking headroom
- Perfect for 5900X/5950X

- Intel XMP-Ready - Our engineers have predefined Intel Extreme Memory Profiles designed to maximize the performance of our memory modules, reaching speeds up to 3733MHz.
The HyperX Fury HX436C17FB3AK4/32 is the fastest RAM kit featured on this list, offering speeds of up to 3600 MHz.
The RAM kit offers a grand total of four RAM cards, with 8 GB memory each. This is both good and bad, however. Right out of the box, gamers will get 32 GB of RAM for their gaming PC which is plenty.
This does, however, limit the consumer in the future, as all four of their RAM slots will be taken up day-one. Most gamers these days build PCs with 16GB RAM cards or more, so starting off with 8 GB of RAM per slot may not be the greatest.
But on the other hand, this RAM kit offers spectacular speeds as well as RGB lighting, which is always great. So at the end of the day, it’s up to the consumer for what they believe is more important: memory or speed.
This RAM kit is also very fairly priced, with it just over two hundred USD.
- Very High Performance
- Nice RGB Lighting
- Fairly priced
- 4/32GB limits future upgradeability
3. G.SKILL TridentZ RGB

- TridentZ RGB Series - 32GB DDR4 kit - 2x 16GB matched modules
- Timings of CL14 (14-14-14-34) at 1.35V
- Unique heatsink design with vibrant RGB LEDs
The G.SKILL TridentZ RGB F4-3200C14D-32GTZR is an excellent middle-ground for RAM.
This kit offers some excellent speeds, with up to 3200 GHz and includes two RAM cards of 16GB each. With two 16 gig cards, this kit leaves room for additional cards down the road if you’d ever have the desire to fill all four of your motherboard’s RAM slots.
Additionally, this RAM kit is also features some very pretty RGB lighting. Its unique heatsink design also sets it apart from competitors by looking truly aesthetically pleasing, with or without RGB lights turned on.
This RAM certainly has a cool-factor going on, and will certainly add quite a bit of character to any PC build.
The only real downside to the G.SKILL TridentZ RGB F4-3200C14D-32GTZR is its high price point; currently still sitting at over 200 bucks, this RAM kit is not cheap.
If you were to look elsewhere, you could easily find other RAM kits of equal speeds for half the price or less. This RAM kit is much more intended for PC builders looking for kits with high performance in addition to a nice visually pleasing look.
- Beautiful RGB lighting
- Great performance, more than enough memory
4. Corsair Vengeance RGB Pro
Best Budget RAM For Ryzen 5900X/5950X
- Dynamic Multi-Zone RGB Lighting
- Next Generation Software
- Custom Performance PCB. Tested Voltage - 1.35V. Tested Speed - 3000MHz. SPD Voltage - 1.2V. SPD Speed - 2133MHz
And finally, we come to the beast of a RAM kit that is the Corsair CMW64GX4M4C3000C15. This RAM kit offers 64GB of DDR4 RAM across four 16GB cards. With so much included memory, your PC will be set for years, without any need to upgrade for a very long time.
With that said, it is a tiny bit unfortunate that the RAM card’s maximum speeds are only 3000 MHz, while other kits on this list can go up to 3200 MHz and 3600 MHz, respectively.
This isn’t a huge downgrade, as the sheer amount of memory is still very good, but it is worth pointing out that it doesn’t offer the fastest speeds.
With that said, Corsair’s offering isn’t all bad. It also features some very pretty RGB lighting, and with all four cards installed together, they certainly make for a beautiful sight to see. The kit is also very fairly priced, with the whole 64GB package clocking in at under $300.
For just over 50 bucks more than the G.SKILL TridentZ RGB F4-3200C14D-32GTZR, gamers get double the amount of RAM with just a very minor downgrade in speed.
This RAM kit is perfect for anyone that wants to fill out all of their RAM slots day-one, while also getting some beautiful RGB and decent performance. While it might look very expensive, purchasing all four RAM cards at once will save the consumer money in the long run, over buying the RAM cards individually.
- Tons of memory
- Beautiful RGB lighting
- Saves money over buying RAM cards individually
- Not the fastest of speeds
Overall, you really can’t go wrong with any one of these RAM kits discussed today. They all have their own positives and negatives, and the best option for you simply depends on your preferences.
While TEAMGROUP T-Force Delta TUF PC4-21300 is by far the cheapest option, it is also the slowest kit by far. The HyperX Fury HX436C17FB3AK4/32, while having the fastest speeds, consists of four 8GB RAM cards, which negates any future upgradability.
If we were to pick one, we’d have to go with G.SKILL TridentZ RGB F4-3200C14D-32GTZR: it offers two 16GB RAM cards with excellent performance, while also looking great visually and offering great RGB lighting.
With that said, each and every one of these RAM kits are great and all come recommended by us. If you’re interested in reading further about these processors, you can check our Ryzen 5900X/5950X motherboard guide as well.
Best RAM For Ryzen 9 5900X / 5950X – FAQs
How much RAM does Ryzen 5900X and 5950X need?
Both Ryzen 5900X and 5950X are flagship processors and designed to dominate heavy AAA titles as well as productivity apps.
The 5900X will go well with 16GB RAM because most games have a recommended RAM size of 8 GB these days. So 16 GB will make sure you remain ahead of the curve and ready for future titles.
The 5950X is targeted more towards the content creators and professionals, so we would recommend a 32 GB RAM for it.
Can I use all 4 RAM slots?
Yes, you can use all 4 DIMM slots of your motherboard but make sure to use the modules of the same speed, same size, and same brand for optimal performance.
In Dual-channel platforms like AMD’s AM4, using all four RAM slots instead of two (using 4×4 GB RAMs instead of 2×8 GB RAMs, for example) can result in slightly higher performance in some games.
What RAM is compatible with Ryzen 5900X And 5950X?
Although the Ryzen processors are compatible with a wide range of RAMs, not all of them are suitable of these CPUs.
These processors are designed to perform well with high-frequency RAM sticks, it’s becoming more and more true with each passing generation.
According to this TechSpot article, 3600 MHz CL16 is the ideal memory type for Ryzen 5900X and 5950X, while other reviewers have recommended going as high as 4000 MHz.
In our opinion, anything equal to or greater than 3600 MHz will be good.
Can your RAM die?
Like all of your PC components, the RAM will die eventually. But it’s a super long process and will take a lot of years in normal circumstances. Some of the factors which play role in RAM dying include heat, power surges, low-quality power supplies, and low-quality motherboards.
Can RAM affect FPS?
No, if a RAM has more memory than what’s the minimum requirement for a game, it’ll be good to go regardless of its size. A higher-speed RAM will get you more FPS than lower-speed RAM, but its effect will be minimal and will vary from game to game.
