I was curious about this too, I asked Roccat about their supposed V2 of Valo when I questioned them about some problems I had, and they said that there was no such revision. Can someone from OCuK confirm this?
My Roccat OSD driver seems to work fine though, so perhaps yours is an isolated incident. Although when I select CPU usage for my LCD it is stuck at 40%, which is apparently a problem a few people are having.
The only gripe I have with this board at the moment (and mine was one of the first) is of course the whine, but also the fact that it doesn't seem to load up properly until it gets to windows. For example, when stating up and you have to press 'Delete' or 'F1' or whatever to get into Bios, I cannot do this, so when I need to change settings or Overclock, I need to change keyboard. Does anyone else have this problem?
