Why We Picked It
The Trident Z5 Neo is G.Skill’s latest offering for AMD 7000 processors. With a blazing-fast speed of 6000 MT/s (spelled as mega transfers per second), it is one of the fastest DDR5 memory modules you can buy for the Zen 4 generation.
G.Skill is a brand that is synonymous with AMD CPUs. The reason for this is AMD normally requires memory to be higher clocked, and historically G.Skill kits have performed very well with them.
This model is no exception in that case. The Trident Z5 Neo supports AMD’s EXPO standard, which allows you to easily overclock from the BIOS using a pre-set profile. After enabling, we were able to run this kit at 6000 MT/s during our mixed suites of tests. The system remained stable with a voltage of 1.35 V, which is a bit higher than what DDR5 supports at stock speeds.
The best part for me was that it looks really good with the right RGB setups. It natively supports AuraSync, Polychrome Sync, and other RGB software from different manufacturers. That means you can easily customize it and sync its color with the rest of your setup.
Our only gripe was that it does not come in white yet, so those looking to build an all-while setup need to look elsewhere. But the matt-black heatsink goes really with a stealth-looking case.
Who It’s For
- Looking for the fastest memory to pair with AMD 7000 series.
- Want to use a built-in overclock profile.
- Has an all-black case.
What We Liked Most
- Super fast clock speeds.

Why We Picked It
The Corsair Dominator has the performance to back up its name. You get super low latencies combined with a fast 6000 MT/s when using the EXPO profile that is built in.
In fact, we even tried to increase the clock speed and marginally tweaked the core voltage. This resulted in the core clock reaching 6200 MT/s quite easily. This is due to the Aluminum heatsink aided by Corsair’s DHX cooling, allowing heat to dissipate quickly.
With Ryzen 9 7900, the high clock speeds meant we regularly got very good frame rates in games. Its high bandwidth came of good use in applications where you need fast memory.
Even though this memory is catered towards high performance, you will not lose out on the looks department. It features 12 very bright LEDS, which can be customized to many pre-set combinations right from Corsair’s iCUE application.
Especially if you have other Corsair products, it fits in very easily. You can basically control every aspect of its RGB elements right from the app. Then a single click can change the whole effect of your setup.
Who It’s For

- »Great performance on EXPO profiles.
- »Superb looks.
- »Comes with great RGB software.
- »Runs at a high voltage.
Why We Picked It
Even though we picked the Corsair Vengeance RGB DDR5 purely on its looks, you are not exactly missing out on any performance.
This is due to a fast 6000 MT/s memory frequency that operates at a CAS latency of 36ns. Yes, this is slower than the others mentioned in this article. But you will not feel this when you are gaming or editing videos.
The memory chips run at 1.40 V to achieve this speed. As a result, this consumes more power. But the included heatsink is more than capable of dissipating it, so heating is never an issue.
It comes with a white translucent plastic that covers the LEDs. This gives it a unique look, with the colors blending really well with the white plastic. When you change the different presets, it really looks cool. And don’t forget just how easy it was to customize custom light effects from the iCUE app.
The Vengence RGB is particularly suited for builds where you pair it with other Corsair components. The ease with which you can control all the RGBs is almost effortless.

How to Buy the Best RAM for Ryzen 9 7900X?
When purchasing memory for your AM5 CPUs, it is a good idea to keep some key metrics in mind. That will help you get the best-performing memory at the lowest prices.
Memory Frequency and Timings
Every RAM is rated to run at certain speeds. For DDR5 memory, this starts at 4800 MT/s. Here MT/s refers to mega transfers per second, which is the data transfer rate between the CPU and the memory.
The fastest DDR5 memory can reach a speed of 6600 MT/s, even though some manufacturers have already breached the 7000 mark in their labs. But right now, for the AM5 platform, the sweet spot seems to lie in the 6000 MT/s mark. So targeting that speed should get you both performance and stability.
After choosing your memory’s frequency, you should try to get the memory with the lowest possible latency. Memory Latency refers to the time between data request and retrieval. Getting one with the lowest latency will improve performance on all your applications. We have covered latency in great detail in our dedicated memory buying guide, which you can go check out.
Capacity
You can buy DDR5 memory in sizes starting at 8 GB. However, you should look to buy sticks of 16 and 32GB due to the ever-increasing memory-hungry games these days.
For gaming, 16 GB should be the starting point. 32 GB should be enough for future-proofing, though. But if your PC will be used for rendering and video editing, getting a 64 GB or higher is not exactly a bad idea. It all depends on how the app you are using utilizes memory. Keep that in mind and allocate your budget accordingly.
Compatibility
There are two things to note when buying the most compatible RAM for your system; memory frequency and clearance with your case.
Check if the RAM that you have selected supports your system. Motherboards have different requirements for memory based on the chipset. A quick look at its specification will reveal the maximum supported memory frequency.
If the RAM comes with a heatsink, that can interfere with the CPU cooler. Then you will have problems installing it. So keep the dimensions of the memory and your cooler in mind before purchasing it.
Build Quality and Design
The overall design of your memory is of great importance once you think about how it goes with the other components of your build. People often get color-matched memory kits to match the case design, even if that requires getting an expensive memory kit.
Also, look out if the memory has RGB support. In our testing, we found Corsair iCUE to have the most robust software to control the light effects. Do check if your memory supports the motherboard’s native RGB app for added convenience.
