Two months ago, we tested the KLEVV CRAS XR5 RGB DDR5-6200 with Intel XMP. Today, the kit we have now is a new revision that includes both Intel XMP and AMD EXPO profiles. This time, our focus will be on the AMD platform, and we’re eager to see how far we can push this kit.

Unboxing
When KLEVV first launched the CRAS XR5 RGB, only the DDR5-6000 and DDR5-6200 kits were available. This time we can see more options from KLEVV that go up to DDR5-8000. That aside, we can also see the addition of the 24GB modules to the lineup, which is known for its outstanding overclocking capability.
These days, most DDR5 kits are fairly straightforward, without many extra bells and whistles, and that’s just fine. When it comes to design, it has a white heat spreader featuring debossed patterns, mirror-finished accents, and an RGB lightbar.

Memory Overview
Most manufacturers nowadays usually offer memory profiles for both Intel and AMD systems (XMP for Intel, EXPO for AMD), but they tend to stick to more conservative settings to ensure compatibility across a wide range of computers. However, if you’re comfortable tweaking the settings, you can often overclock DDR5 kits to achieve better performance. The extent to which you can increase memory speed depends on the quality of the memory chips, as well as the capabilities of your CPU and motherboard.
Since many DDR5 memory kits with Hynix A-die chips have been shown to easily reach speeds above DDR5-7600+ on Intel’s Z790 chipset, in this test, we are using a motherboard with the AMD X670E chipset to find out how the AMD camp handles the kit. Additionally, AMD has made significant progress with its AGESA firmware updates, allowing DDR5 kits to surpass DDR5-6400 speeds. We thought it would be interesting to see how far we could push this memory on an AMD platform.
With the EXPO profile enabled, this kit runs at DDR5-6200 with CL32-38-38-78 timings, offering better performance than older DDR5-4800 kits and even some of the newer DDR5-5600 kits. If you prefer optimizing the performance of the kit instead of overclocking it for higher frequencies, you can consider fine-tuning some key settings.
- tRFC to somewhere around 380
- tRAS to 30
- tRRDS to 4
- tRRDL to 6
- tRTP to 12
- tFAW to 16
- tCWL to 30
- leave the rest on auto
- DRAM voltage at 1.43V
If you’ve been using AMD Ryzen 7000 series desktop processors, you might have found it challenging to reach DDR5-6400 speeds without a high-end X670E motherboard and a top-performing CPU. However, with recent AGESA firmware updates, reaching DDR5-6400 is now much easier, even without a significant increase in voltage—especially if you’re not aiming for aggressively tight timings.
In our experience, we achieved DDR5-6400 at CL28 with minimal adjustments. We kept the sub-timings consistent with our DDR5-6000 CL28 settings, adjusted the primary timings to CL28-38-38-26, and set the DRAM voltage at 1.47V. While this performance boost might not be noticeable during basic tasks like web browsing and office work, it does improve 1% lows in gaming, resulting in a smoother experience.
For experimentation, we tried to reach DDR5-8000 with this kit and were able to do so after several attempts. However, we don’t recommend running the kit at this setting for daily use because the performance improvement doesn’t justify the trade-off in stability and heat management. If you want to give it a try just for fun, it’s crucial to have adequate cooling around the DIMM slots, as the additional heat generated at these frequencies requires proper heat management to maintain consistent stability at higher speeds.
Final Thoughts
Despite its rated speed of DDR5-6200, we’re able to achieve DDR5-8000 with minimal effort and that’s a good thing, especially for users who are experienced in memory overclocking because of the free performance boost you can get without having to spend that extra bucks on kits with higher rated speed that usually comes at a much higher price. For those who are aiming for high memory frequency settings, your result may vary depending on your processor and motherboard setup, as higher-end CPUs and motherboards tend to offer better overclocking capabilities.
All in all, the KLEVV CRAS XR5 RGB DDR5-6200 has demonstrated promising overclocking capabilities on both Intel and AMD platforms, according to our test results. At the price of RM 639, it presents a compelling option for those looking for a quality DDR5 kit—not only for overclocking but also for gaming.
