Performance
Performance has been tested on the AMD platform, including the Ryzen 9 7950X processor, ASRock X870E Taichi Lite motherboard, Colorful RTX4080 Advanced OC 16GB graphics card, Kingston Renegade 2TB NVMe SSD, and FSP 1350W 80+ Platinum PSU.
All results were performed on the KLEVV FIT V 32GB DDR5-6000 memory kit. Our stable overclocking limit was 7000MT/s, but overclocking is not guaranteed. At this clock, the memory could run at respectable timings of CL34-42-42 at the 1.40/1.40V 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, which is probably the best application for checking 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 the difference between the EXPO and 6400MT/s overclocked settings is about 5ns. The 7000MT/s were already lost in this test because of the 1:2 IMC to memory ratio. Even though it has a much higher frequency, latency is slightly worse than the EXPO profile.
AIDA64 tests are fully synthetic and usually do not present real-world performance. The following tests should give a better view of the daily performance.
In PCMark 10, we can see the most significant performance gain between standard settings at the JEDEC profile and the EXPO profile of the FIT V memory. As long as PCMark 10 Applications benchmarks show differences between various RAM settings, we can barely see it in 3DMark benchmarks.
The latest Cinebench 2024 reacts quite well to RAM performance. Even though scores do not seem so different, we can clearly say which memory will be faster in rendering. Again, the most significant gain is when we switch memory profiles between JEDEC 5600MT/s and EXPO 6000MT/s or higher. We must remember that this benchmark takes only a few minutes, and rendering tasks usually take much longer, which may bring more advantages in long-hour runs.
Final Fantasy XV and Superposition benchmarks have all results close to the error margin again.
The most significant improvements are shown in games. At display resolutions like 1440p, the FIT V at 6000MT/s should give us about 3-5 FPS improvements over the standard 5600MT/s memory and the next 2-3 FPS if we overclock it further. We shouldn’t expect significant improvements if we play at higher display resolutions. As long as 1440p is still scaling well, then at 4k, it will be insignificant.
KLEVV FIT V provides high performance out of the box. We don’t have to overclock it to enjoy good results. However, Hynix IC guarantees high overclocking potential, and users who wish can push it much higher than it’s specified.
I will tell you more about overclocking on the next page of this review.
