Performance
Performance has been tested on the AMD platform, which contains the Ryzen 9 7950X, Gigabyte X870E Pro ICE motherboard, Gigabyte RTX5070Ti AERO OC graphics card, and FSP 1350W 80+ Platinum PSU.
All tests were performed on the Crucial Pro OC 64GB DDR5-6400 memory kit. The 64GB memory kit could overclock up to 7000MT/s, but because of possible IMC ratio and loose timings, the best performance could be achieved at 6400MT/s and tighter timings. This is what we used in the comparison, and we believe it will be the most popular overclocking option for gaming. If your motherboard and CPU’s memory controller can handle it, you can expect it from the memory kit. Most new processors and motherboards shouldn’t have a problem with that.
Let’s begin the tests.
The AIDA64 memory benchmark scales well with the memory frequency. With each step, we gain a couple more GB/s. The results are not bad, but could be better. They’re still significantly better than JEDEC profiles.
Latency is also not bad, but could be better.
The difference in synthetic bandwidth and latency tests does not always tell the whole story, so let’s examine other tests.
The PCMark 10 Applications benchmark shows the differences between popular Microsoft Office applications. This time, we see slightly better results at each higher memory frequency. We can especially see improvements in Word and Excel.
3DMark tests show barely any difference at overclocked settings, but if we take a closer look at scores, it’s clear that higher-frequency memory is faster. This matters mostly in competitive benchmarking. The Crucial Pro OC is about as fast in UL benchmarks as memory kits at 6400MT/s and CL30 or CL32.
The new Cinebench reacts slightly better to RAM performance in rendering. It’s insignificant, but we can tell which setting is the fastest, primarily through this long benchmark. The result at DDR5-6400 EXPO is already pretty good compared to the overclocked settings.
The same in Blender, EXPO profiles show pretty good performance and are significantly better than the JEDEC profile. Optimal for AMD is anything between 6000 and 6400MT/s.
Our results in modern 3D games show that the Crucial memory at 6400MT/s gives us optimal results, and anything at tighter timings or higher frequencies on the AMD chipset barely helps.
On the next page, I will tell you more about the overclocking of the new Crucial memory.
