Thank you, I will make a post on the other topic when I do some more tests
I just updated the bios, so I guess this automatically does a clrcmos too. I put very relaxed primary timing at the moment such as 20 20 20 40 and the rest in automatic to try to boot at 4100Mhz, but I keep getting code 61 (and rarely code 23). My ram kit is G.Skill Trident Z RGB F4-3200C14D-16GTZR. I also disabled RBG in the bios, but it doesn't change much. It's just strange that 4000Mhz runs perfectly at 16 16 16 32 (1.40v) and 16 17 17 34 (1.35v), but 4100 just won't boot regardless of voltages or timings.
