Test Setup
We will be utilizing two test systems today, one based on the 13900K CPU and the MSI MAG Z790 Tomahawk Wifi motherboard and the other based on the GIGABYTE B650 AERO G motherboard with the 7900X CPU. We will operate the Intel system using the XMP profile and the AMD system with the EXPO profile.
Our testing will include looking at the Lexar ARES RGB DDR5 32GB (2x16GB) 6000MHz Memory in its XMP, EXPO (6000MHz), and overclocked configurations.
Overclocking
From an overclocking perspective, we focused on the 13900K platform as it has the most headroom related to memory capabilities. We started by boosting the voltage to 1.4V and escalated the memory clock until it did not post at 6800MHz. Dropping down to 6600MHz, we got into Windows and were stable until we fired up some games, to which we quickly crashed back to the desktop. At 6400MHz, we had a fully stable system and were able to complete our benchmark suite.
We elected to maintain the XMP timings instead of pushing those further given the decent bump in memory speed that we achieved.
