Vcore and V-dimm regulation are one of the most important things, that should be avail in bios of our motherboards. Asrock miss that thing, but if you correct that mistake in your products, motherboards branded by asrock will be the best choices for most of sockets (low prize good quality, and o/c abilities). V-mods are too hard for couple of users, but without it, asrock mobos are only a piece of sh***. ;)
Change it, please :)
