Essencore KLEVV CRAS V RGB 32GB DDR5-8000 CL38 Memory Kit Review


Performance has been tested on the Intel platform, including the i7-14700K processor, ASUS Z790 APEX motherboard, Colorful RTX4080 Advanced OC 16GB graphics card, Kingston Renegade 2TB NVMe SSD, and Corsair 1200W 80+ Platinum PSU.

All results were performed on the KLEVV CRAS V RGB 32GB DDR5-6400 memory kit. Our stable overclocking limit was 8400MT/s, but overclocking is not guaranteed. At this clock, the memory could run at respectable timings of CL38-52-52 at the 1.52/1.49V VDD/VDDQ. The voltage is suitable for daily usage in PC cases with good airflow.

We will start with the AIDA64 Memory and Cache benchmark, probably the best application to check memory bandwidth and latency.

The results in the AIDA64 benchmark almost always look better at higher frequencies, so it is no wonder that our overclocked settings give higher bandwidth. It does not always translate into a performance gain in daily work but suggests that well-balanced frequency and timings provide the best results.

The latency test shows that the difference between the XMP and overclocked settings is about 6ns. It’s not so much, and we can say that the XMP is pretty fast, as some competitive memory kits had worse results.

AIDA64 tests are fully synthetic and usually do not present real-world performance. The next tests should give a better view of the daily performance.

As long as PCMark 10 Applications benchmarks show differences between various RAM settings, then we can barely see it in 3DMark benchmarks.

The latest Cinebench 2024 reacts to RAM performance quite well. We can clearly say which memory will be faster in rendering, even though scores seem not so much different. We have to remember that this benchmark takes only a few minutes, and rendering tasks usually take much longer.

Final Fantasy XV and Superposition benchmarks one more time have all results close to the error margin.

Results in games finally show something higher. Less demanding titles or low display resolutions can take advantage of faster RAM. More demanding games at high display resolutions push graphics cards to the limits and don’t rely so much on the CPU or RAM. Then, the FPS gain is not so significant. We have changed one of the benchmarks to F1 22, and it reacts well to RAM performance with a 6FPS difference between the best and the worst pass. However, it wouldn’t matter much as the average FPS is over 200.
It looks about the same in Ubisoft games at 1440p. The performance gain at higher memory frequency is visible, but it’s not very spectacular.

KLEVV CRAS V RGB DDR5-8000 is one of the fastest memory kits we reviewed. Since prices are now lower and keep going down for higher series memory kits, then it’s a reasonable option for a high-end gaming PC. On the other hand, if you wish to save some money, then lower frequency KLEVV CRAS V memory kits will also be great and not so much slower.

I will tell you more about overclocking on the next page of this review.
