There are some modded bios' for them that allow overclocking, they're on a Russian site and quite a few people are having much luck with it. OPnce I'm up and running I'll try them and report back. The bios's cant just be flashed straight over, you need some strings from the bios that it comes with, then you add it to the tweaked bios, flash that and you gain multiplier options and a few others. I'll see if I can find the link again.
I've gone the way of getting the highest clocked 6 core for the system to start with, then until I get the modded bios I'll still have quad-channel and NVME boot as a starter course, then flash the bios once I'm more read up on it for OC'ing dessert.
This is the board I have ordered, it has overclocking options available but no voltage control, but that can be fixed with modded bios, everything else like NVME boot/setup is there though. Huanan deluxe X79
