**UNDER-VOLTING**
Guys it seems the current drivers / BIOS have protection built in so the card won't allow you to under-volt it by any usable amount unfortunately.
Anything below 1225mv seems to trigger protection meaning it won't load to windows desktop until you do a full power off and on.
However going from 1250mv down to 1225mv has reduced temperature by 5c under-load with no ill-effect on stability at stock speeds with the card still set at +50 power with 1000Mhz core speed always.
If this protection gets removed by later drivers/BIOS the card in theory should be able to run fine around 1150-1200mv which should be good for a good 10c+ reduction in temps over stock. Seems you can get them to run pretty cool.
Infact its turning out to be quite a fun card for the tweaker/overclocker.
