No there isn't a limit. The 780 ti rev. 2 bios on the front page of my club includes the fix from evga. I would use that one with the easy flash instructions I have at the bottom of the page. Then open the classy tool and set the voltage to 1.2v and start from there. Start running a bench at like 1200mhz 1.2v and go from there. I would get a dmm so you know exactly what voltage your card is using so you can tell exactly what is going on.

I did a clean install of the drivers after i first flashed the bios. I never reinstalled px though. And i sidnt use ddu 12.8.2 (i dont know what that is) and i didnt use safeboot mode.

Pluss i didnt go over 1.31v and 1306mhz
My card was running unstable at stock base clock though, something not right.

How do i do safeboot?

Ok... I managed to get everything running, properly....

I have a few questions, what a safe max temp?

What should i do with the PEXVVD AND PWM Freq sliders on the classified voltage controller???

Is a certain amount of artifacts acceptable or as soon as you see one should you adjust?

The PWM slider helps the power delivery. Acceptable artifacting is going to vary depending on what you are trying to do, are you going for a game stable OC or are you trying to get high bench scores?

Trying to get a stable game oc so im guessing no artifacts are acceptable. But could you explain the PWM freq a little more... How should i adjust it, what exactly will it do? How do i know how high to put it?

It's kinda hard for me to put together the right words, so I'll quote someone who definitely says it better than I could:

If you're having stability issues with your current voltage then bump PWM.

Edit: And yes, if you are going for game stable then you will be looking for 0 artifacts. You'll also want to test around ingame to make sure you don't get any game crashes.

what bios are you on?

the evga bios fix will throttle at 82c, " safe " is under 90c

watch your vrm temps, the classy vrms' are " safe " up until 120c I believe, but stayind under 100c is the ticket,

I dont have my vrms go above 70c and I was on air cooling only...

KP runs 500-600 on his runs,

I run 508,

pwm is pulse wave modulation, it is the freuqnecy " wave " of power delivery, a high frequency wave will be a smoother power delivery to the card, less distance between waves and an overall more direct power flow through the circuitry.

I'm only " stable " at 1320 @ 1.327 actual load ( dmm ) on air in firestrike

but can go up to 1360 @ 1.315 ish in bf3 / other games. to help you sort out oc's voltage

1.327 load after draw is with 1.35 set with the classified tool,

So im using the evga updated bios, i managed a super stable over clock of 1254mhz on 1.25v at 80c w/o messing with PEXVDD or the pwm freq. I managed 1306mhz on about 1.275-1.3 (not sure what voltage i went up to for that one) but i was getting artifacts no matter what and my temp was getting a little too high for my comfort so i settled for 1254 mhz. Im gonna try 1306 again with a higher pwm freq, hopefully it stabilizes it for me. I want 1306 so bad, lol. That was my original goal. Oh, and i noticed that my card throttled down wen it hit 90c. Maybe they made changes.

you're fine up to like 1.35 set in classy tool on air, it'll be 1.326 ish in reality after load draw, just watch temps and bump up your fan speeds.

voltage will eliinate artifacts and increase core mhz potential, pwm just cleans up the power supply frequency.
