GTX 1080 Overclock

[wuupman]

I have a Evga gtx 1080 gaming gpu that I just got. My stable overcloxk with stock voltage and power limit at 120% is +150 MHz core and 300mhz memory. If I go any further there would be small glitches are the screen. Even when I up the voltage to max it would go to +160mhz core. Any higher would cause the same glitches like artifacts. Is this a good overclock?

Base core : 1607 MHz
Boost core: 1733 MHz
When in game it boost itself to around : 1860-1886mhz with no overclock.

I7-4790 non k

Stable overclock:

Max temp limit
+150mhz core
+300mhz memory

Take in mind that Overclocking has its limits... And Some video cards has more or less OC potential than others and also there are tons of factors that affects the OC.
My recomendation stay safe, dont even overclock it or do it with your stable config.
1st: Overvolting can fry your card
2nd: Overclocking further means more temp the more you OC it, so be sure to have a very cool case properly refrigerated and if you can Watercool your GTX1080 means more potential to OC.
3rd: Take in mind that Overclocking will also draw more potence from your PSU so you can also be risking your PSU health and your Own card health.
If the card already has artifacts you can possibly be damaging it already.

Hi wuupman,

10XX cards have GPU boost 3.0 which auto "overclock" the core frequency at a specific power draw tension and temp.
You can roll back the memory overclock, it's useless for gaming.


What is the temp of the card at 100% load?

No need to raise the voltage limit. It can slowly degrade your card over time, plus it can actually lower your OC potential. This is because of the power limit. By increasing voltage, you increase power draw, which would run you into the 120% limit faster. On Founder's Edition based cards, this will be the case. I had an EVGA Founder's 1080 awhile back. I only adjusted Core and Memory offsets with maxing the power and temp limits, didn't touch voltage In my case, I had a solid boost frequency of 2025Mhz that stayed there, and 10.5Ghz overall the memory. However, mine was custom watercooled. Since you already adjusted fan curves, you're likely as high as you'll get due to temps.

Remember that GPU Boost 3.0 starts to lower boost clocks after around 58C or so. In other words, boost starts to drop off above this point. The lower you can get those temps, the better.
