Why no voltage control?? Gtx670

Nvidia wouldn't lock the voltage down for no reason, voltage above 1.175 has I assume been experimented with by nvidia and can degrade the gpu. these gk107 chips are midrange and over clocked like hell by nvidia to make them look high range, at stock they are already being pushed hard.

They're GK104

That would make sense. Nvidia are already pushing them pretty hard before we get our hands on them! lol

To a point. If you get a little bit of luck you can get from a 1066 boost all the way up to the higher end of the 1200's and even 1300 if you're very lucky.

That's an overclock of 20% (taking 1280) which is not too shabby.

The AMD cards overclock more in percentage terms which is due to them shipping with unusually low stock clock speeds... possibly to counter nVidia's cards with the Ghz Edition's that we're now seeing. However, purely comparing performance while at what you could term a "max OC" the nVidia equivalent of the AMD card performs on par (or better) so the "overclocking headroom" advantage which is sometimes thrown around is a little moot if at the end of it all, the cards are roughly even.

Don't get me wrong. My card clocks not to bad at 1240, was just thinking if we could play with the voltage then a higher clock should be possible.

Mine have more to give on the temperature front as well... even on air. There's probably an unknown variable somewhere which nVidia don't like which is why they're capped at 1.175V.

Degradation, spite, RMA returns... we're all guessing really without any information.

Yeah, mine doesn't even get a sweat on at 43Deg C!

Nice one

As there are many rumours now and posts getting pulled etc saying that basically nVidia don't want them above 1.175V I would say there is little chance of a permanent solution to allow them to be voltage controlled.

I would imagine someone finally will come out with some way of voltage controlling these things. I suppose we won't know how much voltage is really "safe" and how far they can be pushed until that time. - if that time ever comes.

That's the thing. Partners have come up with ways and they have been wrist slapped by nVidia. It needs a combination of software and hardware amendments over the reference model to allow it hence I think it's unlikely.
