Pushing for Speed
With testing out of the way, I endeavored to see if these sticks had any headroom. I left the voltages and timings at their XMP defaults and started increasing the frequency divider until the system failed to boot. At that point, I backed it down to the last bootable configuration and did some basic stability testing using MemTest64.
I was only able to get 3700 MHz out of this kit with all other XMP settings at their default. While higher speeds would boot, they could not pass any stability testing.
For AMD overclocking, I endeavored to find the maximum possible frequency with XMP timings. Next, I set the frequency to 3600 MHz and used DRAM Calculator for Ryzen to optimize the timings. In the case of the Thermaltake TOUGHRAM XG RGB, I had trouble using the "Fast" configuration and had to settle on the "Safe" settings. I then benched each setting with AIDA64 to showcase what kind of benefits you can expect from each. I also included the default (non-XMP) settings as a base reference point.
I was able to get 4000 MHz out of the Thermaltake TOUGHRAM XG RGB on my MEG X570 ACE with the XMP default timings. For timings, the TOUGHRAM XG RGB managed the "Fast" preset without issue.

Looking at the graphs, there is some benefit to overclocking this kit past XMP settings, at least for use with Ryzen systems.
