First off, kudos to EVGA for a stupidly quick step-up process once they actually got 1080 in stock. If not for me not picking Saturday shipping I'd have had my card within 48 hours of them getting my 970.
Anyway, onto the card. After a couple of hours of messing around with it in Precision (and even trying Afterburner) I think my card is a dud for overclocking, unless I'm understanding Pascal overclocking wrong.
I tried doing +100 clock, +300 memory, and I'm getting driver crashes left and right. In Precision, changing the voltage slider on the left (I think I even tried +100%) didn't seem to affect anything. Even with higher clocks set, the boost clock stayed at 1860 in Fire Strike.
Just for the hell of it I switched over to Afterburner after uninstalling Precision just to see if I'd have any better results. I ended up getting +60 clock +300 memory, and that gave me a max boost of about 2025. The only issue is even that isn't stable. Any issues with the card being not stable is solely due to driver crashes. The Afterburner result lasted me about half an hour in Dark Souls 3 and then poof.
I'm totally fine with my card just being a bad overclocker, since it gets to 1931 boost on its own at stock settings (and holy crap you guys did a good job with ACX 3.0. This thing is quieter at 60% than my 970 ACX 2.0+ was at 30), but I want to give it a decent, educated shot when I get the chance again. Any kind of advice is welcome and appreciated. I haven't really played around with overclocking much since I got my 970 a year and a half ago.

u definitely want to do a clean install of your drivers using DDU if u haven't done that already. when in Afterburner, slide the power and temp threshold all the way to the right (120% / 92*c) and then start your overclocking. also, while going for peak overclocking numbers and benchmarks, people usually ramp up the fans to 75% - 100% to limit throttling.

Anything beyond 2GHz is "luck" and depends a lot on the silicon lottery.
What you should do:
- get MSI Afterburner
- Set Power Target to 120%
- keep the temperature target at 83°C
- set the fans to 100% for testing
- test your OC with Ungine Valley in Window mode and increasing your OC in 10-25MHz steps beyond 2GHz
- Do NOT change the voltage!
If you find the first unstable OC, dial back to the last stable OC, reopen Ungine Valley (it has to run during the next testing!). Now press "ctrl+f" in MSI Afterburner. The "first" highest point in the graph looking from the left to the right should be in the middle. Any point further to the right should have the same height. Now... take the point beeing 1-2 steps further on the right than the first one (get a higher voltage point) and dial it (and only that) a bit higher e.g. to 2050MHz. Hit apply in the main MSI Afterburner window, the graph should now "set" all the other points further on the right of the one you changed to the same level.
What you did is to set a higher voltage point for the frequency. You can now dial that single voltage point higher until you hit a frequency/voltage point where your OC crashes. Now you can go to the next voltage point and try higher frequencies. Don't go too crazy here. You might hit the power/voltage limit pretty soon.

Exactly why their is NO GOOD REASON to buy a Factory OC'ed version of GPU's.....they only promise the clock spec's their shipped with, anything beyond that is sheer luck.

True, mine is stable at 2100MHz core and 5500MHz memory. 2200MHz is also possible with the curve editor, but doesn't have any performance advantages.

I just have the SC version because they upgraded the regular version to SC for step ups that were in the queue for a long time. Normally I'm fine getting stock cards. I think I'm gonna have to use the voltage frequency curve. Even without touching the voltage it's saying I'm hitting voltage and power limits when I test +50 and +300. The driver crashes pretty much every time.

On a random note, is it possible that the drivers are the reason I'm not getting good results? I've read a couple of random articles saying that the 1080 is picky about drivers as far as driver crashes go. I've never seen issues with it in my prior cards, but I figured I'd ask just to see if anyone has any experience with it.

http://forums.evga.com/Basic-troubleshooting-steps-Windows-clean-boot-clean-driver-install-debug-mode-etc-m2504606.aspxI'd try doing step number 2 to get a clean install of drivers. If you still get crashes, you should try just OCing the GPU without any VRAM OC first. Try a smaller OC stepping - start with 25MHz at a time, and run Valley (free benchmark) for 5 minutes to see if it is reasonably stable before stepping up another 25MHz. When you get a crash, back off 10MHz and test longer. Then try OCing the VRAM with the GPU OC - I'd start at +100 and add 50 each step, backing off 25MHz when you get a crash. The reason for OCing the GPU first is that OCing VRAM can reduce your max GPU overclock due to power being diverted to the VRAM instead of the GPU. VRAM overclocking doesn't yield nearly the performance increase that GPU overclocking does, typically only netting you 1 to 3 FPS more in benchmarks. Just so you know, the low end for OCing a 1080 is 1900MHz, while the top end seems to be right around 2150MHz.

I'm gonna give it a shot tonight after work (well tomorrow technically I guess) when I have a couple hours to kill. Apparently it's hitting 1930 STOCK with nothing but the power limit raised, so I'm not gonna be too disappointed if I can't do much better.

Does the SC have 2 BIOS? My FTW was getting very poor OC results. On slave I flashed an FE BIOS and now it OC like a champ. Don't ask me why...

Only one unfortunately. It is every bit the same as the FE with a different heatsink.

I already did. I get much higher stable overclocks (and benchmark scores) when I flashed the generic Nvidia FE BIOS. I thought it may have something to do with the V/F curve implementation on Afterburner (latest beta) only working with FE cards. However, I have been unable to confirm this.

Still no luck. Tried a slight overclock on the VF curve past a certain voltage, and even a paltry 40MHz crashed it.
I used DDU to remove the last drivers and clean installed the ones that came out today. After a restart I did +70 on the voltage and +40 after 1.04 volts. Valley ran for five minutes before crashing.

My Founder Edition 1080GTX OC'd +136mhz core(1987mhz) and +500mhz memory(5500mhz)stable. That is more than I ever expected a reference version would pull. Maybe true, but for my 2025-2050 Mhz 1080 SC I also got the privilege of paying $50 less than you did.  I need to go out to the mailbox. My 1080 EK full cover water block should be sitting in the parcel box right now. If it is, and assuming I'm not missing anything, I'll be testing out to see if I get any higher than 2050 MHz this evening on water. To the OP: assuming it's not a driver thing fixed with a proper DDU + reinstall, it's possible your card is simply on the left downward slope of the bell curve. Hopefully you at least beat 2000 Mhz with it, and regardless, I'm sure it's a lot faster than whatever you had in there before. Enjoy it!

Hi. Sorry For my Bad English.
I have evga 1080 SC serios. Recently Relized my GPU Clock and my Memory Clock are increased. The Numbers are:
GPU clock : 1708 MHZ / Memory Clock : 5508 MHZ. The Temp is increased too. In Idle usage it's 45c, If i Close Precision XOC its geting even more Hotter, around 58.
So is this a Problem that im facing here or what? Help me , Thank you.
