Well I ended up going with the 780 Classy over the 290x anyway. Want to get a G sync monitor soon so it made more sense to me.

Anyway, I read that they went up to 1.21 voltage but mine seems to cap at 1.187v. How do I increase it? I was told the new Precision X allows more voltage but that can no longer be downloaded.

Any help would be much appreciated! :D
 
I updated my bios to the Skyn3t bios. However with +100mV offset my voltage is lower now then when I was on old bios?

If I recall my voltage in Heaven went from 1.187v down to now 1.137v.

Which seems odd that it won't do the 1.21. Since I thought that's the max Afterburner and Precision X allowed.
 
Follow whyscotty's link and grab the voltage tool, this allows upto 1.5v! If on air i wouldn't exceed 1.35v max and only for short(bench) runs, you should be ok around 1.28v for 24/7 use if on air.
 
I grabbed the Classy voltage tool. Went as high as 1.325v and nothing made my card stable at 1300mhz core. Heaven artifacts right away.

Seems I got myself a dud.... :(

Does the card work at stock?

If so you didn't get a dud as its working as the manufacturer intended :)

I don't think anyone buys a Classified with the intention of staying at stock.

Since my Classy does not seem to get a decent overclock no matter the voltage I would call that a dud. :)

Still messing with it. Just got it yesterday so we will see how it ends up. Not looking promising though! :D

5 cards in 1 year and not a single good clocker. :(

Well one of my 770s was decent but that's it. Ah well... not like it makes much difference for gaming. Just sucks when you pay a premium on a card with overclocking in mind.

What is considered an average overclock for a 780 Classy at 1.212v?
 
It almost seems as if my card becomes more unstable when I use the Classy tool.

Once I up it to 1.3v it just does not seem to like it at all.

At 1.212 I seem stable at 1241mhz core and 1732mhz memory (so far).

Upping voltage from 1.212 to 1.3v and setting core at 1280 and 1756 memory it crashes pretty quick in Heaven.

Odd how it crashes at barely higher overclocks with all that extra voltage.
 
Try leave your memory stock just clock the core and see what it does and try volts in between dont just jump to 1.3, Good luck :)
 
I did leave my memory clocks at default while I tested the core. Made no difference.

I also did not jump straight to 1.3v. I worked my way up trying to get it stable, but it changed nothing.
 
I also lost the silicone lottery with 780Ti cards(reference-non reference cards),bought and sold around 7 of them,best overclock I got was around 1219 on the core on one card ,rest were around 1100-1140.

Ouch, that's some bad luck there. I plan on stepping up to a 780ti or 880 if they are out before my 90 days are up. I'll just have to deal with my mediocre card until then. :D

Unless the card I step up to is a dud then I'm dead in the water lol.

:( Shame silicon lottery is a bit of a gamble and worse still when you buy a card like a classy
 
Yeah I thought I would be able to get at least 1300 on the core at 1.3v.

Was a real let down that it can't even do 1280mhz. :(
 
Bit unlucky if you can't get 1300MHz at 1.3v anything beyond that would be entirely a lottery - but 1240-1280 is about what I'd expected from the better ocing cards from more run of the mill oc models, not what I'd expect from a classified. i.e. my 780 ghz does 1267 at 1.21v which is about the upper end of what I'd expect.
