I can’t give you a good recommendation, since I find the BIOS to be really annoying, at least with my Hynix SSD. Others are reporting issues as well, but it might depend on your SSD/BIOS combination.
Perhaps i can even change the bios speeds after unlock… Greetings Tom
I don’t know what “BIOS speeds” you want to change (eMMC?), but in my v5 Ezbook it was already set to the highest possible value after I unlocked the BIOS, so I wouldn’t expect that you can increase speeds beyond that.
