Performance
Performance has been tested on the Intel platform, which contains the i7-14700K CPU, ASUS Z790 APEX motherboard, Colorful RTX4080 Advanced OC graphics card, and Deepcool PX1000P 80+ Platinum PSU.
All tests were performed on the Crucial Pro OC 32GB DDR5-6000 memory kit. The 32GB memory kit could overclock up to DDR5-7000 and CL38-45-45 1.40V, which is a pretty good result and, so far, our best with Micron IC. The DDR5-7000 CL38 setting was stable in our tests. You can expect it from the memory kit as long as your motherboard and CPU’s memory controller can handle it.
Let’s begin the tests.
AIDA64 memory benchmark scales well with the memory frequency. We can see that we gain a couple more GB/s with each step. The results are pretty good, but nothing spectacular. They’re still not far from 6000-6200 CL30/32 kits of other brands.
The latency is clearly improved if we compare the Pro OC series to regular modules. 20ns lower latency makes a significant difference.
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 us the differences between popular Microsoft Office applications. The most significant performance gains can be seen in Excel, where overclocking settings are faster than the XMP. It’s also the most demanding test. In everything else, all settings show similar results.
3DMark tests show barely any difference at overclocked settings, but if we take a closer look at scores, then it’s clear that higher frequency memory is faster. I don’t think it matters out of competitive benchmarking.
The new Cinebench reacts slightly better to RAM performance in rendering. It’s not significant, but we can tell which setting is the fastest, especially though this benchmark is quite long.
The result at DDR5-6000 XMP is already pretty good. The lower XMP profile is significantly slower.
Final Fantasy XV and Superposition results at high display resolutions are barely different. The difference between the slowest and fastest settings is not much higher than the error margin. Since the story more often repeats, we will have to think about replacing these two already old tests.
Our results in modern 3D games are also nearly the same as on the black version of the Pro OC memory kit. In Cyberpunk 2077 at 1080p, with disabled Ray Tracing and DLSS, we can see up to 6FPS between various memory settings. In some other games, like the already old Shadow of the Tomb Raider, we can see even up to 30FPS gain. On the other hand, higher display resolutions at higher details rely more on graphics card performance, and then we can see significantly lower gains – about 2FPS in titles like Assassin’s Creed Valhalla. FarCry 6 unexpectedly shows a 6 FPS gain between the lowest XMP profile and the highest OC setting.
The XMP 6000 profile is quite well-balanced between standard and highly overclocked settings, but the 6400MT/s seems like the perfect option for gamers. We wish to see Crucial Pro OC at higher frequencies out-of-the-box, but honestly, it wouldn’t change the user’s experience.
On the next page, I will tell you some more about the overclocking of the new Crucial memory.
