Hi, received the app and it works great.
EDIT: Summary of tests, all were able to underclock memory to 300mhz.
XFX HD5850 Win7 64bit, -v range is 951 to 1100 in steps of 1
HIS HD5770 WinXP 32bit, no voltage control, fan speed reports unknown
Sapphire HD5750 Win7 64bit, -v appears in to be steps of 1, did not test full range.
Would like two feature requests:
1) ability to control fan speed from command line. This way I can script idle/mining/gaming and control temps a little better.
2) bare format (suppress program name and version) that shows date/time and all adapter details in one line, would like to be able to run this every 5 mins and dump to a text file for logging/monitoring
XFX HD5850, 2 monitors attached, Win7 64bit

Just a note.. after undervolting to 1000 I stabilized at 52C.

No luck at all on undervolting. Also can't see fan speed.
