Performance
Performance has been tested on the Intel platform, including the i7-13700K 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 8000MT/s, but overclocking is not guaranteed. At this clock, the memory could run at respectable timings of CL36-47-47 at the 1.45V VDD/VDDQ. The voltage is suitable for daily usage, and memory modules shouldn’t overheat, even in PCs with limited 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 how high the difference is between the XMP and overclocked settings. 64.5 ns at the XMP profile is still a pretty good result compared to some memory kits previously reviewed, but we wish it to be lower.
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.
In previous reviews, we could see higher differences at overclocked settings, while here, the XMP is not so much slower. It confirms that the XMP performs well, even though its frequency is significantly lower than the overclocked settings.
One more time, 3DMark benchmarks barely show any differences in all our settings.
Rendering benchmarks like Cinebench R23 use mainly CPU power. If we used more RAM, then we would see more significant differences. During long rendering on large files, faster RAM may save time.
The same Final Fantasy XV and Superposition benchmarks 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 can see that the average FPS in the Shadow of the Tomb Raider at 1080p can improve even by 30 FPS.
KLEVV CRAS V RGB DDR5-6400 seems like a well-balanced memory kit, which should give high results on AMD or Intel platforms. It also shows very high overclocking potential. I will tell you more about overclocking on the next page of this review.
