I'm not interested in 7970, but i can confirm that rev.1 7950 are not hardware voltage locked. Some of them come with locked voltage bioses, but they can be reflashed... 7950 GB rev. 2 for now are hardware voltage locked. About 7970s - all i know that most of them are voltage locked irrespective of the kind - oc or not.
Most 7970's are not voltage locked. AFAIK the Gigabyte is the only one that is, and I don't know that even that one is for certain. For example, people were reporting that the Sapphire V2 was voltage locked and it turns out that you just need the latest version of Trixx to access the voltage control.
