Hey I'm curious, you mentioned how 1.3 on the classy tool can actually equate to 1.45 - I've been slowly increasing my voltage and clocks and benchmarking in between each change and it appears that my voltage stays near exact what I set it to in the classy tool - it's actually just .008v less than what I set it to (for example, I have all three cards set to 1.25 right now and they're at 1.242v).

I kind of want to set it higher but I'm on air for the time being and don't want to blow these cards up lol. I'm curious if GPU-Z is displaying the voltage wrong or something because I'm noticing a lot of discrepancies between GPU-Z and MSI Afterburner. For example, the aforementioned voltage issue where MSI Afterburner will display stock voltages but GPU-Z will display the correct voltages (what I set them to using the classy tool), temperatures display incorrectly (GPU2 was showing at 92C in Heaven but only at ~82C when I checked it in GPU-Z) and last but not least the core clock only displays correctly on whichever card I am currently monitoring on GPU-Z. When I switch over to another card it just shows it at base clock, but I know this is incorrect because as I was able to increase the core clocks to the point of instability so MSI afterburner is definitely displaying the core clocks correctly (and I'm assuming the temperature as well)

Sorry for the long post rolleyes.gif

According to GPU-z, I am losing just a drop of voltage.. Like 1.35 would be 1.33 or so.. if you use the Probeit connector, you see the truth, and what software isn't seeing. With the Probe-it, the voltage is way higher.

Oh wow. So I shouldn't be running anywhere near this high of voltage on air then I'm guessing?

On a side note, fourth card just arrived biggrin.gif I wish I had waterblocks for these things.


Edit: Well I guess 1.24 would be right around 1.35 then which isn't TOO bad for a quick benchmark, but my friend said not to go above 1.3. Still, I'd just like to get a second opinion on it because the last thing that I want to do is fry one of these cards lol.

How do you switch the bios on the 780ti classified? Mine was on green before I put the back plate and block, have I stuffed up?

Are you asking how to flash it or just where the switch is at?

If you want to flash the BIOS, use the Skyn3t revision 2 bios on Page 1 along with NVFlash on page 1 of this thread.

If you're just looking for the switch, it's a very tiny white switch that is located to the left of the PCI-E connectors.

it has little to do with the LED :-D look at the two 8 pin power connectors, just left of them is the ev bot connector 5 pin plug, a little itty bitty white switch (with the power off, switch it to your right for the second BIOS) and then the Probe it 10 pin connector.

Was just after the switch location mate smile.gif thanks for that.

So I'm assuming bios 2 is the LN2 one correct? Will I need to reflash skyn3t to that bios?

Jusrt eyeball your temps like an Eagle on the hunt.. I suggest the investment of blocks, as they cut them temp in half, with higher voltage, on average. The EK Blocks are pretty, as they are the ones attached to my babies, lol.

yes. Leave the normal bios alone. If you do accidentally flash it, like someone i Know.. *not looking in the mirror, I swear* just ask EVGA and they will send you the stock BIOS for both the normal and LN2 switch :-)

Thanks again man. I lowered them all down to 1.2V just to be on the safe side. EK Blocks are definitely going on these bad boys but it'll probably be five or six months before I can make that happen.

When I had them set at 1.25V via the classy tool, my second GPU got up to 92C max but I'm still assuming that's way too hot since the true voltage was probably more like ~1.4 I'm guessing. Water blocks are definitely a necessity, but I spent so much money on this that I have to hold off on them for a bit tongue.gif

yep, don't rush it.. Take your time and do it right. Just protect your investment until you can get the blocks on them.
