I'm a little confused as to why the UD5H gets a 12 phase VRM, but the higher end boards (including the OC specific SOC Force) only get an 8 Phase VRM. Am I missing something here?

By Asus ROG vs Standard, although std. deluxe versions have hybrid ROG/std. VRM, not quite as ROG but not totally mainstream. ROG has higher quality VRM with more amperes and needs less to achieve same efficiency. I think its the same by Gigabyte.

More isn't necessarily better.....
