Hello everyone! I modified the BIOS on my ASUS VIVOBOOK 15 (X540UV) and opened the hidden tabs (I didn’t change the Advanced and Chipset names to the correct ones, they’re called USB Configuration and Graphics Configuration). However, I encountered a problem: after changing the timings in the OverClocking Performance Menu, they’re applied correctly. However, after rebooting, the laptop takes about 2 minutes to boot and resets the BIOS to the settings that were in place before the timing changes. I opened the hidden settings for undervolting and timing adjustments, since CL15 on 2133 is terrible. Is there a solution? If you need the BIOS file, I can attach it without any problem.
