GTX 660 voltage won't change on unlocked BIOS

[Cynthius]

Okay so I've unlocked my BIOS with Kepler BIOS Editor, the fan and TDP unlock worked a treat, but the voltage slider in MSI Afterburner STILL will not do anything. Voltage readouts don't change a bit. I've got it to a +50 MHz core clock and a +450MHz memory clock and I want to drive it harder, but with this voltage problem I can't. It goes up to 1.175v and stays there, when under load. I can fiddle with voltage all I like but it doesn't change, up or down.

Halp pls

EDIT: I kept crashing so I brought the clock down a bit. now +40/+400 core/memory respectively.

Yeah, I've unlocked the BIOS already, the voltage still won't adjust. I don't see what you're getting at here, sorry.

Could you clarify please?

EDIT: I just realised I used Kepler BIOS Editor rather than Kepler Golden BIOS because the download links for Kepler Golden BIOS don't work anymore.Kepler BIOS Editor is a manual thing, and to be honest I'm not even sure I've adjusted the right slider.

If you have the right BIOS then I have no idea tbh, never played around with a 660
