Lots of people have measured core voltage with a DMM and found that the Classy actually will overshoot set voltage a bit under load, but it's very close. When you set voltage with AB / PX / Classy Voltage Tuner tool you can be fairly confident that what you're setting is close to the actual voltage.

I stand corrected, lol

Just pointing that out. I share you excitement for OCing the 780 Classified. I remember when I first got the skyn3t BIOS and went to 1.212v with PX and got to 1,306MHz. It was awesome. I've found that it's a very fun card to play with. I'm waiting to see you bench at 1,306MHz+ thumb.gif

Other benches that I like to use while OCing are Valley and Heaven.

I'll have to check those out for sure then. Btw what voltage settings did you use to accomplish the 1306 overclock?

I got to 1,306 with 1.212v with skyn3t Rev.3 (Rev.4 wasn't out at that time). It really depends on the card. I have personally experienced pretty different results with these cards. I have had some that will do 1,306MHz in their sleep, and others that struggle to get to 1,280. The one that was a really good clocker was an early 780 Classy with Elpida memory, and the memory did not OC very well. I sold that card to someone who put it on water and was able to bench over 1,400MHz with it.

Kinda off topic but.... Do you have a higher resolution version of your avatar? I've been looking for that exact picture and can't find it!

Here I posted a few benchmark trials using unigine valley at stock settings. This is using the skynet rev 4 bios at 1.212V. The first page is power target, the second is clocks. If you notice on the second page the higher I go on clock, the lower my score goes. This was run at a 100% power target. On the first page once I felt I hit my max clocks, I started upping the power target. by my scribbles you can see that at 160% power target my score shoots from 3293 to 3744. Which leaves me with the conclusion the higher I clock, the leaner the available power, so the more I go, I need to adjust my power target accordingly to have the ability to draw extra power. I don't know if I'm on the money or not, but numbers don't lie in this case, so I hope I'm on the right track
P.S---- Sorry for the ****ty pics, lol biggrin.gif

So you should be fine.

I was helping cobz with his build and his ax1200i wasn't enough for 2 cards in sli at about 1.4v. Shutdown during firestrike run everytime. adding more watts fixed it. We kind of proved to ourself an ax1200i isn't really enough for 2 classy's in sli. But 1.4v should be about 1.5v underload so between 2 cards at that voltage and overvolted cpu that is a ton of voltage used. So if you keep the voltage under like 1.4v you might be ok.


I dont plan on going over 1.35v on both cards and this will be only for quick benches. Will be running them at 1.212v for 24/7 use so from what you guys say i think i will be fine with a 1200w...

It might just be enough.... If 1.35v is under load it will be close.. If set at 1.35v you might have a problem.. Do not forget you are also powering the rest of your system with the same psu correct? I have 2 1200i's and 1 1200i could not power just the 2 cards.. But this was at 1.4v.... You will soon find out if it is enough, if its not, you will know... Hopefully you will be fine... thumb.gif
