Wonder why the 980ti G1 doesn't like voltages above 1.237v? If it uses the same volt controller as a TX or Ref 980Ti it should be able to push 1.274v (max actual).

Most people with TXs run 1.274v if possible.

Not sure if the new BIOS they posted will address it or not. We'll be testing smile.gif.

It is difficult to even catch it if you aren't looking for it and happens so fast it may not even affect scores.

The results are still coming in but I think many who have testing found that additional voltage (like with V1/V2BETA here) didn't allow more overclocking headroom from stock (1.237v). Likewise, when we went to 1.218v in V3BETA I don't think anyone had to lower overclocks indicating that the same MAX BOOST speeds ran at the lower voltage.

Time/Testing will tell tongue.gif

Your MIN is 30% / 1260 RPM. That needs to go in PER01 (30) RPM01 (1260)

Then should be good unless you were trying for fanless, then see below wink.gif

The way I have it right now it can actually go lower than 30%. You're right though: the fans keep turning on and off at a certain point, so I suppose I'll try setting the min to 10%.

EDIT:
That actually didn't seem to change a thing. I set it to min 30 now.

Hey, Actually i got better temperatures with my side fan blowing air onto the GPU in my Fractal R5 Case.

I have 2 front fans in, 1 side fan in, 1 back fan out and my H100i pushpull on top that is blowing out.

I now have this fan setting, it keeps the GPU temp at or under 70c when heavy gaming or Heaven benchmarking at 4K Max settings and the fan stays off till 45c

So I did a little more temp testing tonight. Turns out the OSD was only set to show a single temp and that temp was of the top card. I changed it to show both and the bottom card averaged around 65-68 degrees while the top card was around 80-83 degrees. I changed fan directions on the fans over the cards and it didn't seem to make any difference if I sucked away hot air or blew in cool air. No matter what the bottom card is turning the gap between the cards into a little oven. So I need to find a way to effectively remove the hot air from in between or add enough cool air in between to feed the top cards fans.

I wish the bottom pci-e slot on my mobo was x8.

that's weird

have you tried to set 1.312v and see what happens?
