Plus 7950x undervolted to negative 27 on all cores. These settings all together are rock solid. I tried many overnight Y cruncher sessions, gaming, editing, EU5 editor with demanding sample scenes and also let the PC to idle on desktop for long periods of time. Works perfectly.
Thanks to help of people in this thread, as I have very little idea what I’m doing. I think the RAM OC could be pushed even more in my case, but I just lack the knowledge and patience. This is good enough for me.
Behold my push pull 420 AIO and RAM cooling solution (3x 6k fans, capped at reasonably quiet 3k). Both AIO and RAM coolers had to be attached by questionable DIY methods, but hey. It works.
