I didn't want to spend weeks of my life fine-tuning every little value so I mostly copied Buildzoid's timings from his C26 6000Mhz kit video (I have the same kit). The only thing I changed was the CL, 30>32 to allow the RAM to run at a lower voltage.
So here are my timings: https://i.imgur.com/fyMlii8.png
I confirmed the current preset to be stable at 1.57V DRAM voltage with many hours of TM5 DDR5 Ryzen3D and Karhu. Anything less than that and it errors out. Ram runs at 40C during gaming and ~44C during stress tests. I used to do a lot of DDR4 overclocking but DDR5 is new to me so I'm looking for any advice to improve further upon this.
