Some more tests on our so beloved tool:

5 x 5870 - all cards can be clocked / over- / undervolted

5970 - tool shows first core with an unavailable fan (which is true), second core is shown with fan; both cores and memory can be adjusted quite easily. Fan cannot be set below 60% manually (seems to be blocked by firmware).

That's it from my side for the moment.
