Klevv Bolt XR & Cras XR RGB 4000MHz 16GB Memory Review

Compute and Productivity Tests

Thanks in large to its single-rank IC configuration, Klevv’s 4GHz and 3800MHz setups cannot compete with the higher capacity dual-rank kits in 7-Zip compression. Corsair’s single-rank 3600MHz Vengeance RGB Pro SL modules are outperformed by Klevv’s faster set, though, provided capacity differences are not a concern.

7-Zip decompression is more favourable on the 3800MHz setup with Klevv’s kit whereas the out-of-the-box 4000MHz configuration drops to bottom place. This is thanks to the improved memory controller performance  for the 1900MHz FCLK and UCLK configuration.

Blender is also best on the 3800MHz setting whereby Klevv modules match higher capacity and tighter latency Patriot sets. The 4000MHz setting is left towards the chart bottom, joining Corsair’s single-rank 3600MHz modules.

Cinebench again does well with the 1900MHz FCLK and UCLK benefit of the 3800MHz DDR4 mode. This once again highlights the benefits that higher speed memory – through increased Fabric Clock flexibility – can bring. 4000MHz mode on Klevv with the slower memory controller clock still manages to outperform Corsair’s chart bottom.
