Olde XFX 7970 DD Voltage Control?

[Dangerous_Dave]

Hi all,

Does anybody know how to unlock voltage control on an XFX 7970 DD? I've got the latest MSI Afterburner, but while ticking the extended overclocking limits options opens up the clock rates I can set, ticking the unlock voltage control box doesn't seem to open that up.

Any ideas?

Yeah it's a custom PCB. No voltage control?

Trixx did let you add some voltage, should still do, if it doesn't use an older one.

Failing that make your own bios and set a higher voltage yourself.

Is the lack of voltage control not a hardware issue then?

So far this one's refusing to acknowledge it even runs on electricity, but I'll try the other Trixx soon.
