Since Sapphire refuses to fix their Trixx software I have to take matters into my own hands now. I can no longer adjust the voltage of my card using software. This card has no voltage support in Afterburner and I'm pretty sure it's a custom implementation. In addition to that, it does have a BIOS switch, despite being a non reference design. It also shipped with the shaders unlocked.

The problem is, RBE does not show voltage adjustments for this card and it also throws an Overdrive error when it initially loads the BIOS.

Any ideas?

Here is the registry adjustments to take care of your issue using Sapphire Trix:

Go to registry and disable Ulps:

[HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet001\\Control \\Cl ass\\{4D36E968-E325-11CE-BFC1-08002BE10318}]

and change "EnableUlps" to 0 under the 0000 and 0001 or 0003 keys.

I've already tried that. It's a no go.

I need to manually adjust the voltages in the BIOS.

You cannot edit voltage on 6-series card in BIOS, driver detects change in BIOS and driver will fail to load. Voltage control must be done by software or physical volt-mods. :(

Crap. Last time I buy a Sapphire card!

Does anyone have a 6970 Flex Edition? I would love to flash that.
