Crucial 64GB DDR5-4800 Memory Kit Review

Performance

Our test platform contains an Intel i5-12600K processor, ASUS Strix Z690-I Gaming WiFi motherboard, and EVGA RTX3060 XC 12GB graphics card. All tests were performed on Windows 11 Pro x64 with the latest updates.

Our comparison includes overclocking results and settings at which the Crucial 64GB DDR5-4800 memory kit was stable. The maximum stable frequency using the mentioned motherboard was DDR5-5400 CL38-40-40 1.2V. Results with MSI Z690 Unify-X and Aorus Z690 Master were about the same.

The tested memory kit is dual-rank, as I mentioned before. There was no point in adding results on single rank memory kits to the comparison as in our tests, they’re nearly the same. We could see differences in DDR4 or earlier generations but at least the current platform can’t utilize dual-rank RAM. It still gives us a higher capacity, so we can confirm that the performance on a dual-rank memory kit is not lower at the same frequency. This situation was happening on DDR4 as higher capacity RAM required more relaxed timings. I assume we will still see even higher capacity modules at 64GB or 128GB. Right now, the retail market doesn’t really need them, so also manufacturers are not focusing on higher capacities for home and office computers.

As usual, we will start with AIDA64 Cache and Memory benchmark, which is probably the best software for synthetic memory speed tests.

Memory bandwidth, as usual, scales well with memory frequency. We could pass 80GB/s in our tests and it can be higher if we work some more on sub-timings. Out of the box, modules can pass 70GB/s in memory read, write and copy bandwidth.

Even though latency isn’t any special, Crucial DDR5-4800 has about 5ns better results than regular DDR5-4800 modules or typical SPD JEDEC settings. After overclocking we could easily drop it next 7.5ns.

PCMark 10 is showing us high performance in mixed load tests. In this test, we can see that even not the highest frequency of our memory kit gives us high performance, not much worse than that of top DDR5 kits. Our overclocked results are nearly the same as the default profile of the Crucial memory.

It’s time for some 3D benchmarks from UL.

Depending on the whole PC specification, we can often see more significant differences between RAM settings. In this case, results are nearly the same in all settings.

The same we can observe in all UL benchmarks from 3DMark and VRMark series. Overclocking gave us a 1FPS gain which is more of an error margin than the real difference.

In the Final Fantasy XV and Superposition benchmarks at high display resolutions, we can see that all results are very close to each other. However, the final scores are nearly the same at the default profile and overclocked settings.

Benchmarks based on popular games are usually showing us higher differences in scores. This time, even games are showing nearly the same performance at XMP and overclocked settings.

Regardless of how we see DDR5, the new memory series is fast even at standard settings. Crucial improved the performance and at given high capacity, we should be satisfied with results. A quick conclusion is that no matter how we set current higher capacity modules, the overall performance will be nearly the same, so it’s not worth spending time on overclocking. There will be always users who want something more, so let’s move to the next page where I tell you some more about overclocking of the Crucial DDR5.
