Luckily, AMD has an open attitude towards allowing users to tweak settings to their heart’s content, so all of this is adjustable in BIOS. The optimum settings involve ensuring that the RAM speed matches the Infinity fabric frequency 1:1.
Using our Patriot Viper 4400Mhz memory kit, which comprises Samsung B-Die Ram with CL19 timings, we were quickly able to establish that our Ry zen 5800X was stable at 4000MHz with Infinity Fabric (Folk) at 2000MHz. Note that the scale starts at 5000 Points: The difference between these results is small enough not to cause concern, and it’s not possible to consider this a ‘trend’ in performance owing to the marginally lower scores at higher speeds.
Cine bench R20 appears almost oblivious to the RAM speed of the System with even 2133MHz not causing a significant performance deficit. Moving onto key gaming benchmarks, we looked at Rainbow 6 Siege and Shadow of the Tomb Raider.
Both of these titles demonstrated the benefits of faster RAM on Zen2 and again showed the negative impact once the 1:1 infinity fabric to memory clock ratio was broken. Rainbow 6 Siege Here we again see the same performance scaling to 3800MHz, followed by a slight tailing off as RAM speed climbs higher.
Despite maintaining a 1:1 infinity fabric ratio throughout, we’re seeing a similar but less pronounced softening of performance past 3800Mhz just as we did on Zen 2. All tests were conducted at 1080p medium on a GTX 1080 Ti but even that induced a GPU limitation due to the prodigious speed of the Ry zen 5800X.
Finally, we can now make confident recommendations on the basis of these results, which are in line with those obtained by experienced overclocked: 3600MHz RAM is still the best option for Ry zen CPUs. To obtain RAM significantly faster than 3600MHZ prices jump from around $80/16 GB for 3600MHz CL16, to $100 or more for 4000MHZ CL18 which as our investigation above shows will be marginally slower on Zen3.
Finally, investigations by Gamers Nexus indicate that dual-rank Dimes may be slightly faster, making a 32 GB kit in 2×16GB Configuration at 3600MHz likely to be ideal for most people. Using 2 dual-rank 16Gb Sticks with 3600MHz frequency and tight 16-19-19-39 timings mean you’ll be as close to optimized as one click can get you just by enabling the A-XMP profile.
32 GB RAM provides ample for productivity, the most demanding games and light creative work such as video editing. This is the RAM kit we’re confident meets the needs of almost everyone looking to take advantage of the prodigious power of the Zen3 CPUs for gaming and general use.
The 3600MHz speed enjoys widespread compatibility with Zen3 CPUs, whilst the quality of the E-Die chips lend themselves to tweaking and overclocking for even more performance if the mood takes you. The kit ships with discreet black anodized heat spreaders that integrates well with most builds, but it is also available in white or red if that better suits your preferences.
We’ve got a soft spot for a set of four RAM sticks with synchronized RGB here at Premium builds and the G. Skill Trident Z Neo DDR4-3600 CL18 kit certainly scratches that itch. The core specifications are solid with 3600MHz and CAS latency of 18 so your CPU will operate with a near optimum 1800MHz infinity Fabric Clock.
Corsair is a long-standing brand and their LPG line is ubiquitous so obtaining matched RAM for future expansion won’t be a problem. If you need to pack as much RAM as possible as sacrificing a little speed for cost and capacity makes sense which is why this kit is a great buy.
In this iteration they are claiming to have bested Intel in all metrics making these the most powerful consumer CPU’s available. In this article we’ll cast our attention to Zen3 and examine how we anticipate the CPUs will react to RAM speed changes.
Much of the generational improvements in Zen CPUs have been down to reducing memory latency problems and optimizing infinity fabric. Therefore, we can surmise that there are limited improvements in the infinity fabric speeds beyond normal production refinements that occur over time.
We can therefore safely deduce that infinity fabric speeds will not increase massively in Zen3 : AMD’s performance enhancements have come from other areas. There is another major clue left by AMD: In their own benchmarks for the exceptionally high-performance RX 6000 series GPUs the test bench systems use 3200MHz RAM in combination with their Zen3 CPUs: Clearly, AMD are not concerned about ‘slower’ RAM negatively impacting system performance even where their commercial interests are invested in showing their products in the absolute best light.
This mirrors our own investigation where whilst frame rate improvements are observable, they’re at settings levels that artificially induce a CPU bottleneck. We can see from this graph the wide availability and affordability of RAM at 3600MHz, spanning CL 16 and CL18 timings and ranging from $60-$80 for the majority of 16 GB kits.

If you need to pack as much RAM as possible as sacrificing a little speed for cost and capacity makes sense which is why this kit is a great buy. We’ve selected the Bertram for AMD Zen3 5600X, 5800X, 5900X, and 5950X processors to help you get the best out of the new Ry zen chips.
AMD announced support for higher memory clock speeds over Zen 2. But more on that later, let’s first check how memory channels and ranks can impact your gaming performance.
When building a computer, most people tend to focus on memory capacity and frequency. Well, that works great for most users, especially if building a PC for daily use and maybe some gaming.
If you install one memory stick to your PC, you’ll be running in a single-channel configuration. Gamer Nexus affirms having four memory sticks instead of two yields 10% performance increase.
AMD and AGES are working on new BIOS updates, which will bring optimizations for 1900-2000MHz fabric clocks. That means you will be able to achieve a 1:1 ratio with 4000MHz memory and 2000MHz Infinity Fabric (FOLK) for optimal performance.
But if you don’t want to spend a fortune on these kits, getting a 3600MHz memory with lower latency should do your setup justice. This RAM kit consists of two 16 GB sticks running at 4000MHz, which should be the “sweet spot” once AMD works with AGES to reach 2000MHz fabric clocks.
The Trident Z Royal Series 32 GB Kit is dual-ranked, so you get the benefits of quad rank operations with only two sticks. This model features highly polished silver aluminum heat spreaders for efficient heat dissipation allowing for maximum performance and extreme overclocking at lower temperatures.
On top of that, you get a unique crystalline RGB design to bring your gaming rig to life. The best features of the G.SKILL Trident Z Royal Series 32 GB Kit is not only the likely 2Ghz infinity fabric but also you get the benefits of dual-channel and four ranks operations, which improves performance efficiency.
You can tighten the timings in the BIOS, but so you know, you’ll be adding instability to your system with no significant performance gains. The Trident Z Royal Series 32 GB Kit offers excellent performance without any extra tweaks and tuning.
PROS High 4000MHz clock speeds Great aesthetics Decent timings Solid build quality with heat sink You can customize the RGB lights to match your gaming rig via downloadable software, such as ASUS Aura Sync, depending on your motherboard.
Onboard it has efficient heat spreaders and a handy fin design to ensure higher performance at lower temperatures. In terms of performance, the G. Skill Trident Z RGB DDR4-4000MHz boasts 4000MHz speeds and a CAS latency of 18.
However, you’re still losing some performance efficiency compared to the G.SKILL Trident Z Royal Series 32 GB Kit since this memory is single ranked. If you put four of these memory sticks, you will get the benefits of four ranks, which improves performance efficiency.
If you want the best memory for AMD Ry zen 5900X processor, look no further than the Crucial Ballistic MAX RGB 32 GB Kit. You can add four (4×16 GB) sticks of the Crucial Ballistic MAX RGB, which gives you four ranks for that extra 10 percent performance boost.
You also reap the benefits of having a higher 64 GB memory capacity, making it the best configuration for any high-end gaming rig. The Crucial Ballistic MAX RGB 32 GB Kit is also a top contender for the best -designed memory.
That’s because until AMD and AGES release the next BIOS update with 2000MHz fabric clocks, you can only hit 1800MHz FOLK at the moment. The Corsair VENGEANCE RGB PRO 32 GB Kit with 3600MHz clock speeds and C18 latency makes an excellent option for 5800X and 5900X Ry zen builds.
The Corsair VENGEANCE RGB PRO 32 GB provides good performance gains with only two sticks since it is dual ranked. You can also easily achieve a 1:1 ratio for your memory clock and the Infinity Fabric for optimum performance.
Make sure your infinity fabric runs at 1800Mhz, and you will hit sweet performance scores. The memory also promises better performance and stability, thanks to its highly efficient aluminum heat spreaders.
Corsair VENGEANCE RGB PRO 32 GB is a nice RAM kit that will make justice to your mid-range and even high-end Ry zen build. It takes advantage of four ranks with only two sticks and a 1:1 ratio with a 1800MHz infinity fabric, which should be easily attainable.
