i asked the responsible bios engineer to seperate northbridge and htt multipliers and it took me weeks to convince him that this is possible to begin with...
Yeah, that would be definitely the best and most logic way to adjust that option, also this is the common way by nearly every other brand like asus, ga, asrock and so on. It is hard to understand that especially foxconn cannot implement this matter of course. And I didn't mention the issue that the CPU NB voltage also cannot be modified.
