Both switches on adds more to your voltage.

You're looking at 1.3v load when gaming/benching with both on. Add 62mV in AB or Precision and it becomes ~1.36v load.

1.3v load on air is too much, just leave the one switch(default) on by the pci-E side, then it's about ~1.25v. The opposite side switches just turns off protection to core and memory.

And the 2 other switches are for +25mv voltage each.

And yes, its safe to run, just watch your temps.. thumb.gif

first two are for OCP protection - they should be turned off (position 1-2) only on LN2 or some other extreme cooling solution (tthey are ON by deafult - position ON)

the other two have both the same function - they add +25mv to the core (so if they are both ON its +50mv to the core). If I remeber correctly, one is ON by default and other is off (1-2 position))

hope it helps ya

Thank you guys!

So, is it safe to leave the protection off or should I just leave it on for gaming and turn it off for benchmarking? Or does having it on make overclocks unstable whether gaming/benchmarking? Or is it too risky to leave them off under any conditions besides ln2?

you can easily leave it ON and be good.

it is for those guys, who are pumping XXXX volts to it when benching with ln2 / phase / etc. and the card is pulling incredible power through it.

but now when I am thinking about it, if you flashed skyn3t's BIOS on your card, its max TDP is 900W, so I guess 2 switches for protection are useless anyway thumb.gif

Haha! True! I didn't think about that and I definitely will be using sky's bios! I always do. Pretty much necessary. thumb.gif

Oh and MrTOOSHORT, does the voltage read accurately in either precision/afterburner when you enable these switches. Say I turn them on, would it show 1.3v?

dont know if it was my mistake or not, but when I flashed skyn3t's BIOS, I wasnt able ti raise the voltage via EVGA PrecX.

Now when I flashed 3888_75.rom (link is few pages back), I am able to do so.

It doesnt reeally matter, becouse you can always use voltage tool, but its interesting

and only difference between skyn3t's and 3888_75.rom is that skyn3t has boost disabled

just got my best score on AIR. KPE cards are beasts:

no they read only up to 1.212v - > use GPU - Z.

it also has VRM temp sensor if you scroll down a bit

@h2spartan

Need a DMM to read the voltage correctly. The voltages I mentioned are with a DMM (multi-meter)

On the side note, I have the cash to buy a regular 780TI Classy, and can pick it up today for $882, but IDK yet hmm....
