Should you even bother overclocking the GDDR6X memory on an RTX 3090 or RTX 3080? In this video, I showcase the performance gains that can be achieved with GDDR6X overclocking on an RTX 3090. Additionally, I illustrate that it's a little nuanced this time around thanks to Error Detection and Replay (EDR).
Please note that the results I present in this video are specific to my hardware configuration. Your results may be better or worse depending on a variety of factors.

The RTX 3090 is locked to a frequency of 2100MHz by using Nvidia SMI. Instead of the frequency decreasing as the temperature decreases, the voltage increases as the temperature increases. For a tutorial on using this method to lock your clock speed, see the following video:
