You should also be using curves for core clocks to reduce any droop.
It is with the curve , actually MSI AB scanner OC was used here , lol but it gave the same +136 as i could get manually . Im not going to push this card anymore because i want it to last another 2 years as it seems there is little reason to upgrade anytime soon unless i want to spend $1800aud . Ive had it since june 2017 and another generation at least is my new goal .

For me and both of my 1080TI FE cards +590 on memory is the sweetspot. 1Mhz higher and it drops performence. I think somewhere there the timings get worse or so

I tried the XOC bios last night, and after a bit of experimenting i found out that i got worse performance in games with 100 more Mhz on the core. Disappointing to say the least. Ended up at 2075 core and 6177 mem using afterburner. I didnt bother testing different memory speeds, as i got to the goal i had, which was to have rock solid 60fps in 1440p in all areas of MHW with as close to maxed out as i could. From what i understand, you can gain performance with lower memory clocks sometimes? Is there maybe a post i have overlooked which explains all the little tricks and tips for overclocking 1080 Ti/Pascal?

XOC is mainly for liquid nitrogen / overclocking competitions. Yes you get lower performance per clock with XOC bios but that is usually made up by being able to go +200 to +300 or more Mhz over what you could on any other bios, and the higher voltage and no power limit. It's not really for air cooled stuff at all and not really great for water either.

Any idea why my Fire Strike graphics score has dropped to 28k, I used to get like 31k before. All other benchmarks seem fine though. Seems like gpu usage is only 95-96% constantly during Fire Strike.

could be the power setting in the nvidia control panel. What CPU do you have?

9900k, I have all the power settings on max performance.

Here is my result from Fire Strike, I should be getting upwards of 31k graphics score with these clocks.

For comparison my Time Spy score seems perfectly in line with others.

what would be an average oc on these cards? i cant seem to get more than 60MHz even with more voltage added.

Maybe your card needs repasting and it's overheating and throttling it's self? The 1080 Ti's are 2 years old now. That's about long enough to replace the TIM in most video cards.

You need to tell us what your actual core Mhz is that your card is reaching when you play games, -NOT- the offset from afterburner. And I'm referring to what the card sits at when gaming after a few minutes, not the initial peak clocks when you first start the game. After you play games a while and the card heats up it will drop it's clocks to an average core Mhz. By the way: +60 Mhz means absolutely nothing. The resulting core Mhz from +60 Mhz will be completely different for every single 1080 Ti Owner. Remember these cards use Nvidia Boost 3.0, they are already self-overclocking before you even touch afterburner. 1800 - 1900 mhz core clock is pretty standard for an air cooled 1080 Ti.

Nah, my temps are fine below 50c. If someone could run Fire Strike and post screenshot from this graph for comparison, it seem that my GPU usage during the 2nd test never goes above 95% and can drop as low as 93%.
