G.SKILL Trident Z5 CK RGB DDR5 8400MT/s 48GB CU-DIMM Memory Review

Cinebench 2026 shows that the memory performance can affect the rendering performance overall here. Moving up to XMP Profile 2 actually improves performance by 2.3%. Enabling XMP Profile 1 at 8400MT/s improves performance by 4% over the default. At 8800MT/s, performance is about the same.

In the Blender Benchmark under the monster scene, moving up to XMP Profile 2 improves performance by 1%, while XMP Profile 1 improves performance by 3% over the default. 8800MT/s regresses slightly, but is still above default.

There seem to be larger differences in the junkshop scene, with the higher memory speeds being beneficial. Enabling XMP Profile 2 improves performance by 3% over the default, and XMP Profile 1 improves by 4%.

In the classroom scene, the results are smushed pretty close together. There’s an ever-so-slight difference in support of the higher memory XMP profiles, but it is very small.

In the V-RAY 6 benchmark, there is a clear advantage with the higher memory profiles. Enabling XMP Profile 2 improves performance by 2% over the default. Enabling XMP Profile 1 improves performance by 4% over the default, and 8800MT/s slightly regresses.

When transcoding video in HandBrake, the higher memory speeds make a definite difference in speeding up your video rendering. When we move to just XMP Profile 2 at 6400MT/s, the time reduces by almost .10 seconds. Moving up to XMP Profile 1 improves that even more and has the quickest render time at 7.19 minutes and seconds.

The higher memory profiles do wonders for 7-Zip compression performance. Even just simply utilizing XMP Profile 2 at 6400MT/s improves compression performance by 8%. However, when you enable XMP Profile 1 at 8400MT/s with CL40 timings, the best performance is achieved and is 17% faster than the default 6400MT/s performance.

In decompressing, performance is only slightly affected. XMP Profile 1 is 2% faster than the default setting.
