After that it is a matter of fine tuning the frequency to the power point. Using driver 368.51 helps too.

Thanks for the link. The new driver actually did seem to help a bit. Keep bumping into the power limit all the time so hardly ever get close to 1.1V. Hope there'll be custom BIOS eventually so this annoying limit can be bypassed.

I was finally able to order my EVGA GTX 1080 FTW from EVGA's website!!! Now the waiting begins...

I have been running 3dmark with my 1080 and have been seeing some really strange results. Everytime I run 3dmarks at the same clocks my final score is always differnt by about 100 to 200 points. I have never seen this before all my other cards would always show the same scores with maybe a slight differnce of 20 to 50 points. Is anyone experiencing this issue is this normal. I looked at the clocks and they are not downclocking been beating my head against a wall trying to figure out what is wrong. Any help or adivse would be greatly appreciated thanks

I have been playing around with the curve in MSI Afterburner. Didn't have much success in getting a higher clockspeed BUT i was able to practically eliminate it downclocking.

On the curve graph, you just need to change one of the points. For example, I chose the point at 1025mV. I changed the value to 2063MHz.

Heaven has been looping for 10 minutes now, with no throttling at all and a max power usage of 113%. I'm thinking as long as you can find a stable overclock that doesn't reach 118-119% power usage then I don't think you're going to see any throttling at all.

The only downside of this is that your maximum clock isn't going to be as high, but on the other hand you aren't going to see any clock speeds bouncing around.

Pascal is capable of some pretty robust error correction, so probably best to actually assess performance/productivity at high clocks. You may find that a stable 2100+ core is actually giving lower FPS than a lower clock would (ambient cooling. cryogenic cooling has effects on signal margins). Just my 2cents.gif

Seems to be the case. Just ran some benchmarks using the curve compared to just putting +170 and even though the clocks are higher on the curve, the +170 is getting about 3fps more. Interesting.

I'm always stable on heaven, I mean my clocks are stable at 2114mhz all the time without changing as long as I can mantain low temps with 100% fan but in games everything changes, I've actually tried now what you just said in your post but sadly is not working for me I still achieve for example 2063mhz like you do but in games I bounce from 2050 to 2063mhz now. It's the same with my old OC, bouncing from 2114mhz to 2088mhz. Kind of hating myself for not waiting for an Evga Hybrid 1080 lol

So we should test the FPS gains with the Core OC like we do with Mem OC? for example if I gain like 5 fps with mem at 463mhz but the games feel choppy, at 400mhz they stutter less and I only gain 4 fps but at stock memory I don't see any stuttering but I lose all my fps advantage.

Hi, that was me having that issue and I have a MG278Q. My issue was fixed with a clean install.
I have another drama that wont go away. When running 2 sli ribbons my PC will boot @144hz but after opening any 3d app will revert back to 59hz, then I need to reboot to get back to 144hz
Any one have any insight to this?
