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 128GB DDR5-5600 memory kit. The 128GB memory kit could overclock up to 6400MT/s, but because of possible IMC ratio and loose timings, the best performance could be achieved at 6000MT/s and tighter timings. We used this in the comparison, and we believe it will be the most popular overclocking option for gaming. Most new processors and motherboards shouldn’t have a problem with this setting.
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.
Since the memory kit is high capacity and the EXPO profile is quite standard, we can’t expect low latency. Once we adjust timings manually, the results get slightly better. The 64GB 6400MT/s memory kit, marked in purple, runs at about 20ns lower latency. If we decide on a memory kit for gaming, the Pro Overclocking series seems a better idea, and we won’t need more than 64GB capacity.
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 can see slightly better results at each higher memory frequency, but it’s not as significant as we could see on some other memory kits.
3DMark tests show barely any difference at overclocked settings, but if we examine scores closely, it’s clear that higher-frequency memory is faster. The Crucial Pro is about as fast in UL benchmarks as memory kits at 6400MT/s.
The new Cinebench reacts slightly better to RAM performance in rendering. It’s insignificant, but we can tell which setting is the fastest, especially through this long benchmark. The result at DDR5-5600 EXPO is already pretty good for the given settings. The lower EXPO profile is significantly slower. It’s related to the AMD Ryzen memory controller, which works best between 5600MT/s and 6400MT/s.
We can see the same story in Blender, which favors memory capacity over frequency.
Our results in modern 3D games show that the Crucial Pro memory at 5600MT/s is not the fastest option, but we won’t see the difference in most titles. We tested more games than those three presented, but most act like Avatar or Assassin’s Creed series rather than Cyberpunk 2077. In short, most games at 1440p or higher display resolution will barely show FPS gain on faster memory series. Cyberpunk 2077 is one of the exceptions that gives us even 8FPS more on the Crucial Pro Overclocking at a 6400MT/s.
On the next page, I will tell you more about the overclocking of the new Crucial memory.
