I'm pretty sure I'd be GPU limited with my RX 5700. Maybe once I can source a RX 6800XT for a reasonable price! Dang scalpers are smoking crack!Massive clock for a regular cooling! This is the highest IF clock I have seen till now.
It would be interesting to test scaling from lower IF and memory clock, let's say 3200MHz XMP to your max, tweaked setting in few select games (low res, CSGO, F1, other) and applications (not Cinebench as this won't scale).
It's still a work in progress. My b-die kit seems like it's up to the task. It's playing around blind with all the timings and memory controller related voltages that's the time consuming part. Viewing the Dram Calculator which craps out at 3866MHz isn't much help at all.
