I did that right after i got the card and i remember correct it was pretty low. Around last 5x or start 6x. Will tjek again when home and post it. The system i use is a 2500k@4,7 ghz aircooled with a ultra extreme 120 with push/pull fans, 2 ssd vertex 3 and 4. The mobo is a asrock p67 extreme 4, gen. 3, and a Zalman ZM-850 watt psu.
To the people who asked for a Sapphire guide for volt i did following:
- changed to the non boost bios with the button on the card
- Installed trixx 4.6.0 and enabled force constant voltage (helped on the drop in volt under load for me)
- Now just change volt and i use gpu-z to check drop under load and see vrm temps and so.
Again really love this. Had a trifire setup with flashed 5970+5870 i loved alot, but the strengh in antialising, image quality and so i just love this.
