Asus GTX 1080Ti Strix Overclocking Help

Here are my settings in MSI Afterburner.

I was wondering whether or not my power supply is affecting my overclocks as the max core clock increase I'm able to get out of my card is +100. Anything more than that would result in crashes and unstability. It seems as though other people are able to get 2100mhz easily while I'm only maxing out at around 2050. Is my card a dud? Or are there other factors like powersupply or settings that can affect my overclock limits.

2050 is very standard. If you raise the target power limit and temperature limit you can squeeze a few extra mhz. But really unless you can push the voltage above the locked 1.093v, you are limited on what you can do. 2100 is not easy and I don't think many people really get that stable 24/7.

You did good... Asus doesn't seem to get as high clocks (GPU and memory) as some other brands . Take note of the voltage comments below

Use any tweaking utility of your preference of course. We use AfterBurner. Our applied tweak:

Core Voltage : +85%
Power Limit : 120%
Temp. limit : 90C
Core Clock : + 60
Memory Clock : +400 MHz (=11.8 GHz effective data-rate)
FAN RPM: default

Our sample was not the best overclocker. We noticed the more Voltage 100% offset applied was less stable. We ended by lowering it to an offset of +85%. Memory as well, we noticed some artifacting at 500 MHz under a stress run, 400 (x2 DDR rate) thus an added 800 MHz was the maximum. It's still close to 1.2 Ghz though. Once overclocked keep this in mind: Due to the dynamic nature of the boost clock, your frequency is not fixed. Limiters and monitors, temperature, load, power and voltages will continuously alter a maximum clock state.

As it says above the stability of your overclocks depends on multiple factors one of which is PSU is chosen:

1. Any voltage controller in any component the PC is charged with providing the desired voltage and maintaining that voltage. Its ability to do that job is in turn dependent upon the MoBos voltage control ability which in turn depends on the PSU. So the better the PSU quality with respect to voltage stability and noise under varying loads, the easier job the MoBo and other components have .

2. If you look at the performance of PSUs, voltage instability and noise increase with load... so the closer you get to the rated power of the PSU, the more voltage instability and electrical noise will be present. Hence the rule of thump of 1.25 (casual gamer) - 1.50 (OC enthusiast) times maximum anticipated load.

With good PSUs, good MoBos, we used to b able to tweak the BIOS and take advantage of the beefier construction of the better AIB cards. But Boost 3.0 puts a big nerf on performance capping the clocks no matter how much more they "could go".

Thanks for your help guys. Maybe in the future if I'm adventurous I'll find out how to unlock the 1.093v limit since my temperatures are only hitting 40+ to 50+ max under load.

The only way around the voltage lock is to physical hotwire the card or download the Asus XOC BIOS. That will automatically put your voltage to 1.24v and you cannot change it.
