I've decided to open new (and close old one) thread about new ATT beat versions with HD 4xxx support. Today I've received two HD 4850 and I must say BIG THANKS to everyone who made this day! I really appreciate it!!! :thumbup: Big thanks to Bhairava. http://sna696.helloweb.eu/ray/index.php ________________________________________ Already implemented: 1. Temperature reading 2. Overclocking with voltage control (on 4850 you can set one step higher voltage than stock 3D voltage. Tested by me with multimeter 3. FAN control __________ And if you guyz have any ideas and bug reports from old beta version , you can post it here in new thread. ________________________________ Permanent link to beta version http://cid-a50350ea7a969f0c.skydrive.live.com/self.aspx/Public/attsetup.exe ___________ Known issues: - ATT doesn't show real clocks from registers of video board. So if for example you set 1099 for memory in real it can be for example 1075. I'm working on it right now.
