Hey, bro, I also need XTU for Bios version XMAKB3M0P130D,please send me donwload link, many thanksWorked!
I went ahead and tried it anyway. It worked. Now the undervolting options are unlocked in Intel Extreme Tuning Utility, and I was able to undervolt my cpu to -0.105V without crashing. However, I did not see much improvement regarding the temperatures, and the laptop still throttles when the cpu works at 100%. I have not yet checked if the battery life has improved or not, but it probably did so.
I would be glad to share it if someone tells me how to extract my BIOS in that format.
