More/better VRM means better power regulation to your CPU and RAM. It is important if you heavily overclock.

Someone correct me if i'm wrong
8+2 means eight phase for the cpu and 2 for the memory, I believe. The more phases it has, the more reliable the power delivery to the cpu is.

Semi-correct. The more quality phases it has, the more reliable power delivery is. 24-phase Intel boards don't actually overclock as well or stable as boards with, say, 8 to 14 phases, because they use better phases. Of course, this is AMD and somewhat a different story.

When cranking the voltage up it can be more stable.
