Pushing for Speed
With testing out of the way, I endeavored to see if these sticks had any headroom. For Intel, I kept the same procedure I have been using, leaving all settings at their XMP defaults and then increasing the frequency until the system loses stability.
I was able to get 3900 MHz out of this kit with all other XMP settings at their default.
For AMD overclocking, I wanted to dig a little deeper. First, I followed the same procedure as with Intel 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 Vengeance RGB Pro SL, I had no trouble using the "Fast" configuration. 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 only able to squeeze 3866 MHz out of the Corsair Vengeance RGB Pro SL on my MEG X570 ACE with the XMP default timings. For timings, I was not able to achieve either the "Safe" or the "Fast" presets.
