Installation and Configuration
We installed the Skywalker Plus DDR4 64GB (2x32GB) 4000MHz Memory into our MSI MEG X570 UNIFY motherboard that is paired with a 5900X processor.
By default, the modules load up the base timings but throwing the XMP/D.O.C.P. switch bumped it up to PC4-32000 (4000MHz) at timings of 18-22-22-42. We were able to boot into Windows 11 and start benchmarking without an issue.
Test Setup
We will be utilizing our test system based on the 5900X CPU and the MSI MEG X570 UNIFY motherboard to test memory today.
Our testing will include looking at the Skywalker Plus DDR4 64GB (2x32GB) 4000MHz Memory in its default and XMP/D.O.C.P. (4000MHz) configurations and then seeing how high we could go with an overclock on the modules. Note the FLCK was left at the default 1800MHz for the AMD platform.
Overclocking
From an overclocking perspective, we found some, but not a lot of headroom to drive a bit more speed out of them. As they are the middle of five parts, we’d expect that better-performing ICs would get binned into the faster products.
We boosted voltage to 1.45V and got to work, initially finding that a bump to 4200MHz was a no go at the standard timings. We loosened the timings up to 20-24-24-46 and were met with stability in our testing suite. Whether this trade-off of timings in exchange for a bit more speed is worthwhile will be shown in the performance graphs.
