Current version 1.61: http://www.mediafire.com/?6tx6wewldrdr5p4
IF you really feel the need to donate, switch pool to BTC Guild or Eligius (if you aren't there already)!
History:
1.61 Reads hard limits on each GPU placed by the GPU BIOS.
1.6 Added GPU clock/voltage/fan controllers. OSDs now display temperature if "Pause mining when..." is checked and the GPU number is filled in. The GPU number used in monitoring temperatures is changed to use Adapter Index.
Finally! I am a happy camper! Are you sure mining @ BTCGuild or Eligius is the only barter you'd like for your work? I bet many of us here are willing to donate some coins.
Oh, is the Temperature checkbox working now? With 1.5 I was not able to edit the temp values. Thanks again for heading my requests! Arguably the best GUI Miner out there.
EDIT: It's working now and the temperature OSD is great. However, it seems it is just reading the temp of 1 GPU for both (Crossfired Rig).
The OC clocks seem to limit to just 775 GPU Core from 725, I read here, you followed the lock or something. I hope you can like put a checkbox to lock/unlock for more overclocking headroom.
