780 Classy or 290x Vapor X?

You can use voltage control but even if you set it manually in Afterburner adding +250 it limits the voltage to approx 1.367. In tri-x if I add +200v it reports 1.352. It won't do 1.4.

That's a bit disappointing.

Have you tried flashing a different bios? That should work. Try a Tri-X bios. :)
 
Would be interesting to know. I no longer have mine to test it.

Also @ win8.1, Whats you voltage at in Unigine Heaven? My Vapor X never stayed above 1.3v. At the very start it would be 1.35 and then slowly drop down to 1.3.
Once you get to the ship it would be back to around 1.29.

:eek:Don't try a Tri-X bios, the Tri-X is a reference board with custom cooler, the Vapor X is custom pcb with custom cooler, chances are it'll blow up.:p

Sapphire has outfitted the Vapor-X with a 10-phase digital power design, Black Diamond chokes and a couple of other interesting features attached to the custom PCB.

My Vapor did 1175 as well. Left it at 1170 though even though I had no issues with hours of playing games at 1175.

Card ran great in games. The black screens and lines across my screen out of games was what sucked. :D

Using +250v manually in Afterburner it has reported 1.375 but running heaven 4 it will droop to below 1.30 but the average is around the 1.3v mark. Clocks will stay at a constant 1225/1600 though without dropping. Best I could get was 1623 at 1920x1080 8aa extreme tessellation ultra quality.

Yeah same results as me then. Though my Vapor would never do 1225. Can get a run at 1215/1700 but start getting artifacts towards the end of the bench.

A shame they can't get more voltage really. My temps were still perfectly fine and could have got a bit more out of it if it allowed more.

I tried 1700 but in the Skydiver benchmark it would crash. It needs higher volts to get past 1225/1600 for me without artifacting/crashing in anything.

If the clock is too high in 3dmark Icestorm demo it will artifact in the first part of it were it gets a very high amount of fps. It also might pass most benchmarks but when it comes to Firestrike extreme it would produce blue flashes if clocked too high. The 1225/1600 is the best I can get at the moment passing all benchmarks.
 
The cooler is great on the Vapor and that's the main reason I bought it as for 24/7 use you can run it at fairly high clocks and very low noise. :)

Are you wanting me to kill my card Ltmatt. :) Would need a custom Vapor bios that unlocked the voltage further.

Very true. Good job I did not follow Ltmatt's advice this time. :)

Haha oops. I doubt it would blow up mind. You never know, it might work. After all, that's why you have two bios switches. ;)

I can understand not wanting to risk it mind. Seems a shame that Sapphire have chosen to limit the card like this at the higher end.

I don't understand that, its not just Sapphire, I think even the 290X lightening is limited.

Why?

How is it that you and I with Reference PCB's can pump 1.4v into them right out of the box, and; with a few tweaks can pump as many volts into them as we like while apparently top of the line custom PCB's are limited to 1.3v?

Something I always wonder as well. Get these awesome custom coolers and PCB's that should allow better overclocking and they always limit them! :mad:
