XFX 7950 Double D - Locked Voltage??

[nV_Jason]

Hey Guys, recently got one of these cards and i cant seem to get any sort of voltage control via afterburner even with unofficial overclocking enabled and voltage control tick boxes checked...

Ive also tried Trixx and found that i could adjust the voltage to 1130mv

Ive scouted the net and not really found anything about these cards having locked voltage. Wondering if somebody could shed to some light on how to get it working or let me know if their cards are the same as mine!

Have you gone to settings in order to enable the change in voltage?

These GPUs are laser cut to disable volt adjustments. I can't even get round it with afterburner and it's unofficialoverclocking hack. The sliders move fine so it looks to work okay. But it just doesn't/won't.

I have the same card and can confirm they are voltage locked, with Trixx I can adjust the voltage with the sliders, but it doesn't actually do anything. In Afterburner it's disabled all together, even with unofficialoverclocking enabled.

It's a shame really for a card with such good cooling to overclock worse than reference cards.

They are voltage locked and AB won't unlock the voltage regardless of what you tick/enable.

Trixx/Asus unofficial Gputweak(http://rog.asus.com/forum/showthread.php?24233-unoffical-GPUtweak&country=&status=) unlocks the voltage on locked XFX cards, but Gputweak doesn't remember the settings upon reboot, Trixx does.

I have the same as you, as you can get 1.13v through Trixx, then you have added voltage.

Your max voltage of 1.13v is exactly that, the max voltage available as you have a high Asic gpu=lower stock voltage.

If you had a low [email protected] it would let you go to 1.3v.

the DD's heatsink is flawed due to not letting any air from the fans cool the vms, when oc'ing the vrams get very hot and causes crashing/artifacts.

Such a shame, i bought the card only because of how well they can overclock. Might just sell it and get another

I've just got round to installing one of these and mine too is voltage locked. Think I'll send it back.

Edit:

Tried overclocking it at 1.13V does 1200mhz on the core! Maybe its not all bad at all!
