Overclocking GTX 1080

[Hydra]

How far should I be able to bring the core clock and memory clock levels? I've been able to add 182 MHz to the core clock and 407 MHz to the memory clock without crashing my games. I also added 12% to core voltage. The only problem is that this only seems to add like a few fps to my gameplay. Keep in mind that I usually play all my games at 4k ultra and tend to never to below 75 fps without these overclock settings. It's still strange that it only adds a few fps even though these seem to be big changes in settings. I'm new to overclocking, so any help with this would be appreciated. Thanks!

Overclocking a video card, to me, is wasted effort unless you can truly get big overclocks with stability and not having to increase the voltages. Every card is different and there is no definitive answer to how high you will be able to overclock it.

Theres really no reason to overclock the ♥♥♥♥ out of that card, unless you want to throw it in the trash, it already performs at its fullest, massively better than 90% of gpu's that are out on the market right now.

At least be thankful to have such fps on 4k, there are others that struggle to squeeze 30 fps at 800x600 res.

Just pay a visit to LowSpecGamer on youtube to see what I mean.

Use a benchmark to do a comparative analysis of the overclocking results, not "what FPS it seems to add." The GTX 10 cards overclock themselves automatically quite a bit already, depending on temperature, power, and voltage limits.

Pascal has a hard lock of 1.094 volts if you have good cooling this might add 1-2c to your card. So adding votlage isnt a big deal anymore you should easily hit 500-600 of the memory but above 182 on the core isnt gonna get much better. At that point its better to improve cooling so you keep the core mhz higher since they are so heat sensitive. Every 3-5c takes about 26mhz off of mine

Pascal is mostly temp and voltage limited. GPU boost 3.0 effectively makes it pointless to overclock thanks to these limits. So even if you put in a 200mhz overclock from 1600mhz, it'll automatically go up to 2100 on its own if temps are low enough and you have enough power left.
Highest temp estimates I've commonly seen are 55c. After that, it begins to move up and down. This can be changed with oc software. Voltage is also limited at 1.094. This is locked.

Do note, the vram shares power with your chip. So overclocking the memory is proportionally gimping your core.

The only ways around it is using a custom bios, either by buying a custom oc tier card, or finding a working custom bios and flashing your card.

I'm running sli 1070's and my max oc is +175 mhz gpu and +605mhz (+1210mhz effective) ram. I usually run +133 gpu and +400 ram and 100% power limit, the max oc requires the 112% power limit or it won't run.

Difference isn't groundbreaking (roughly 10% boost) but it does help especially with more demanding games, I only use the max oc for benchmarking as the top card gets mighty hot even with custom airflow.

Note: my cards stock speed is 1.5ghz and both hover below 1.9ghz on furmark without the oc, with the oc they reach over 2ghz. Same with ram, at stock speeds it doesn't get as many fps as with the oc applied. I also run a custom fan curve since these 10 series cards like to turn off the fans completely and only kick in at like 60 degrees.

Well you can shunt / power mod your card to allow considerably more voltage, it just won't report accurately as your essentially shorting the components heh, as for memory, around d the 400-500 mark you'll likely start to get artifacting and issues.

What boost clocks are you achieving and what exact 1080 are you running?
Personally I like to run uningine bench marks looping to tinker then 3dmark firestrike to actually bench my overclocks.

Temps on 10 series cards are very important, once you hit 64c you'll begin dropping from your max clocks and once the cards get to the 80 range the speed tends to drop alot.

In MSI afterburner feel free to slide the power bar to max, no real harm will be done, depending on the game a solid of can add 5-10 FPS, looking at your games, well, they aren't the most demanding, something like pubg or wildlands will really appreciate the oc, GTA also I'd suspect.

Every card us different, I've had 7 evga 1080ti ftw3 elites and everyone of them ran at different speeds and would overclock a differing ammount, my final pair both run at around 2076MHz, but one card only takes around a 60MHz of to get there and won't go any higher, while the other is at a 140MHz of to get to the same point.

Yeah I guess I won't bother trying. I just heard stories of people adding 20 or more fps and I thought it was interesting. My stock settings seem to be more powerful than the results I've seen from a titan, so I guess something is special about this card. Thanks for informing me on this!

[Kaihekoa]

A 1080 isnt more powerful than a Pascal Titan, you're probably looking at an old one.

[Monk]

Yeah I am afraid you are no where near as fast as a pascal titan or a 1080ti, hell if you play some demanding games I wouldn't even expect 60fps max settings at 4k on a 1080.
