ZADAK Spark RGB 32GB DDR5-6000 CL40 Memory Kit Review

Performance

Our test platform contains an AMD Ryzen 9 7950X processor, Gigabyte B650E AORUS Master motherboard, and Powercolor RX6800XT Red Devil 16GB graphics card. All tests were performed on Windows 11 Pro x64 with the latest updates.

Our comparison includes overclocking results and settings where the ZADAK Spark RGB 32GB DDR5-6000 memory kit was stable. The maximum stable frequency using the mentioned motherboard was DDR5-6400 CL36-38-38 1.40V.

We will start with the AIDA64 Memory and Cache benchmark, probably the best application to check memory bandwidth and latency.

AIDA64 bandwidth results are high, but the overclocking results are clearly better. The EXPO profile performs well, and its bandwidth is as high, if not higher, than that of competitive DDR5-6000 CL40 memory kits. Considering how easily we could set CL36, I hope that ZADAK decides to release lower-latency memory kits soon.

Latency results at EXPO settings are a bit better than at competitive memory kits with Hynix IC. It’s a matter of safe settings for some timings, and overclocking results usually change this situation. Our overclocking results show much lower latency without much work on the timings table.

In rendering tests like Blender, the differences between various settings are insignificant. We can still tell that the higher frequencies or lower latencies improve the performance.

PCMark 10 Applications benchmark shows the performance gains from overclocking more clearer. Differences are mainly visible in Excel and PowerPoint.

3DMark series benchmarks show results close to the error margin. In all tests, RAM overclocking barely helps.

The same barely visible differences are in Final Fantasy XV and Superposition benchmarks. We can’t make much more to gain higher performance on these fast platforms with already fast RAM.

Even in popular games, we can’t see a big difference in our settings. At a lower display resolution in Tomb Raider, we can expect about 6FPS better results. At higher resolution, it’s between 2-3FPS. Even though there are some FPS more, it won’t change the gaming experience, so we have to ask ourselves if the hassle related to RAM overclocking is worth it.

Our results show we can expect high performance at the EXPO profile, but those who want something more can read a couple of words about overclocking on the next page.
