I have been trying to undervolt my 13600k with Gigabyte B660M Gaming X for ages. At first nothing would work, because I believe IA CEP is enabled, and even if you disable "Undervolt protection" in bios, nothing changes. As soon as you apply even -0.02 offset, you start loosing performance in cinebench r23. Naturally, undervolting in Windows with XTU or Throttlestop also doesnt work.
Now this is where it gets interesting. I flashed the oldest available bios which supports 13th gen, and "Undervolt protection" setting is gone from bios. Undervolting in bios still results in loss of performance, BUT, strangely, undervolting now works with Throttlestop. I applied -0.1 offset to core and cache and cinebench score actually increased from usual ~23800 to 24100, while consuming 145w instead of 180w. Also I shaved atleast 15c from cpu temperature. So obviously undervolting works perfect now. So Im kinda happy, but instead of autorunning Throttlestop, I would love to just achieve the same using bios. It doesnt make sense to me, if IA CEP (Undervoltage protection) is kicking in and not letting me undervolt in bios, shouldnt it also block undervolt with Throttlestop? Wth is happening here? Appreciate any ideas or explanations
