Which 7970's have unlocked voltage?

post #1 of 16
Thread Starter 
I was almost set on buying a Gigabyte Windforce until I realized revision 2.1 is voltage locked frown.gif

Which non-reference cards are currently unlocked? I need a non-reference card so I can fold at night and still sleep at night smile.gif

Also, I wouldn't mind buying used, so if any one has a voltage unlocked card, shoot me an offer wink.gif

I can't find any current threads on it.

The MSI 7970 lightning is what you are looking for. thumb.gif

Unlocked Digital Power
- Unlocked BIOS: One click to unlock all protections for extreme overclocking
- Digital PWM Controller: More stable and precise voltage by digital signal
- Enhanced Power Design: 2X Power output for maximum OC potential

ASUS & Gigabyte lock their cards. Some sapphires too I believe.

PS: I've heard the Sapphire Vapor-Xs overclock very well. But its pricey.

That's the last card you want due to its seriously low asic binning. Ya want something typically binned higher. The problem is hoever that all these customs have gotten out of hand and its impossible to tell what you're going to get nowadays. You used to be able to get the Sapphire 7970 OC which was a reference pcb with an extra phase and Sapphire binned these typically with high asic which is ideal for folders/miners. With high asic cards, you can actually undervolt the card at moderate overclocks which will save you valuable dollars in savings on your electrical bill. Ask someone like sugarhell for more on that. IIRC he's running 1000/1500 at less than 1v.

A I said above, the problem is that these AIB are always changing their skus so you never know what you get. The 7970 OC card is now gone and replaced with the Vapor X pcb. That totally bites and the 7970 OC is not as attractive as before the change.

So these low binned lightnings run much hotter? So then what is the point of these custom cards. Are they aimed only at the sub zero overclockers?

Yea this is what made me decide to keep my TFIII 7950. just feel like there aren't any good 7970's on the market.

Can someone provide a link about this ASIC value and what it actually means? I keep seeing it mentioned but have no clue as to what it is.

As far as i understand it, ASIC % is based on overclocking potential of the IC's under different cooling methods. A lower ASIC is better suited for LN2, where as a higher ASIC 80%+ is water and air suited.

Interesting. Thanks,this makes more sense now that I realize its the ASIC Quality Value, rather than just ASIC (Application Specific IC) Value lol.

Will check this out on my own 7970 when I get home. After reading those threads, I'm still confused as to which actually gives you better OC , higher or lower ASIC Quality lol.

Well. I still haven't decided...

I'm thinking I will open a WTB thread soon, buy a reference card, and than get a Arctic Xtreme Cooler for it. That would be quiet, have excellent cooling, and I would know what I'm getting.

Any objections?
