Performance
Performance has been tested on the latest AMD platform, including the Ryzen 7 7800X3D processor, ASRock B650E PG-ITX WiFi motherboard, Nvidia RTX4070 FE 12GB graphics card, and Lian-Li SP850 850W Gold 80+ PSU.
All tests were performed on the Crucial Pro 96GB DDR5-5600 memory kit. The 96GB memory kit could overclock up to DDR5-6400 and CL38, which is more than I was expecting from such a high-density IC. The DDR5-6400 CL38 setting was stable in our tests but didn’t pass extended stability tests. It’s what you can expect from the memory kit, as long as your motherboard and CPU’s memory controller can handle it. As we know, it’s not so easy on AMD and 1:1 IF/IMC ratios with 32GB and 48GB memory modules.
Let’s begin the tests.
AIDA64 shows us how well is scaling the memory with frequency. In synthetic bandwidth tests, the latency affects results less than in DDR4, but it’s still visible. Because of more relaxed timings, the EXPO#2 at 5200MT/s is sometimes even faster than the EXPO#1 5600MT/s profile. Overclocked settings, as usual, are better than the guaranteed manufacturer profiles.
The latency at EXPO profiles is just standard for DDR5 at such a high capacity. Sub-timings make it work, and it’s hard to improve it, like 16GB or 24GB memory modules. We can still expect to lower the latency by 10-15ns with some manual adjustments and a higher frequency.
The difference in synthetic bandwidth and latency tests does not always show the whole story, so let us look at other tests.
PCMark 10 Applications benchmark shows us differences in popular Microsoft Office. The most significant performance gains can be seen in Excel. It’s also the most demanding if we use various macros and add-ons. We can see that the 5200MT/s profile is faster in the most demanding Excel test.
3DMark tests show barely any difference at overclocked settings in all our settings.
Since the new version of Cinebench was released recently, we also switched to the new 2024 version.
The new Cinebench reacts slightly better to RAM performance in rendering. It’s not visible much, but we can tell which setting is the fastest, especially though this benchmark is quite long.
Final Fantasy XV and Superposition results at high display resolutions are also barely different. The difference between the slowest and fastest settings is not much higher than the error margin.
Even modern games don’t react much to all the RAM changes of the Crucial Pro memory. Manual overclocking gives us up to 4FPS gain, int he best case scenario, so it’s not even worth spending the time on overclocking and stability tests.
Crucial Pro DDR5 is designed for high stability, low temperatures, and a reasonable price. We can’t count on the highest performance. On the other hand, the performance of the tested memory kit is pretty good, considering the memory capacity and relaxed timings. It looks even better on AMD chipsets than Intel. Especially when we use it with a Ryzen X3D series CPU, the large and fast cache will cover RAM’s latency.
