Thanks, I am really satisfied with the result.

Voltage curves are just another way to OC. Instead of adding one offset to the entire card, you control the offset added at each voltage. It lets you get a higher stable OC at load, but gives you higher efficiency when idle. I have a hybrid kit on my card. It never gets over 43c.

I'm using stock voltage settings on a Evga Founders Edition 1080 GTX,  it has never surpassed 64C to date. All I did was alter my fan curve to 50C=60%, 55C=70%, 60C=80%, 65C=85%, 70C=100%
43C is damn cool but that's due to the add on hybrid kit right?
 

Yes. the hybrid kit helps quite a bit in the way of cooling. It decreases temps while increasing OC potential. 

You are not really adding voltage, just increasing offset at higher volts. I maxed the voltage slider for my card, as it give the card access to %100 of the possible volts drawn. When I added a 200Mhz offset using the slider method, it would crash because it was trying to push too high clocks on too low volts. By creating the curve, I did not add any volts, I just told the card to add x amount of offset at x amount of voltage. This means if the card is idle and volts are low, I can tell it not to use an offset and increase power savings. When the card is under load and volts are high, I can tell it to use a high offset which is stable only at high volts. This is what make the voltage curve much more effective then stranded slider overclocking.

Yeah using the normal core offset it won't use enough voltage on load so it will insta lockup. The manual curve is how I roll. Just one setting is all I use at the clock I want it to run at load. So a block at +175 @ 1.050v and hit enter and all set at 2190mhz on water cooling of course. Can run at +200 at 2115mhz but at 1.093v but feel it's not worth the difference.

Let me add that my cards won't drop clocks during use and stay happy at 34-36c under load. If your card will start dropping clocks and it drops and uses a much lower voltage then it may cause it to lock up.. so a full curve may be the better way to go.

yup i love using the custom curve to max out points where the card hits at from 1.062v and 1.050v i get really good stable clock under load playing games and benchmarking software.

Using fixed offset on my 1080 Classified I can get max stable clocks for benchmarking at 2164MHz, starts at 2177MHz but drops down to 2164MHz when temperature has leveled out.
 
Using a fixed curve of +125MHz and then "adjusting" only the higher voltage points , I can benchmark at 2202MHz stable and +500 on memory...still testing though :D But ONLY adjusting the higher voltage points and leaving "the rest" at stock gives substantially lower results.

How much are you adjusting your top clocks?
