Question about Gtx 1080 and Overclocking.

[Alinashul]

hello Guys ,

I bought monday the Asus ROG strix gtx 1080 ( Not OC edition , the normal one ) , by default it has 1607 mhz Core clock and 1734 Boosts clock , but actually it boosts up to 1900 i saw it .
But today i decided to do an overclocking to see how much it goes more or less .
I used the MSI afterburner :
i added a +220 mhz to the Core clock and a +250 to the memory clock ( yes i could've gone much higher but im more interesed in core clock ) .i moved the TDP up to 120% linked with 92 C temp.
I tried Furmark at 1920x1200 with 8xmsaa and i did a test for like 5 minutes and it boosted up to 2090 mhz and the max temp was 68 C .
Then i try the
Valley benchmark in 1920x1200 extreme HD and it went on all 18 scenes with the temp hitting 69C and boosted to 2130 mhz.
EDIT : the fan speed did not go above 47%

I DID NOT TOUCH THE VOLTAGE in MSI AFTERBURNER .

Then i added +30 ( so now +250 ) mhz to the core clock and i tried furmark for a few minutes and everything OK .
In Valley benchmark at the 16th scene i got error. it boosted up to 2180 mhz.

My question is :

Is furmark or Valley good for testing ? what setting should i use ?
How can i make sure an overclock is stable ?
I guess that if i move up the voltage , i can go higher on the overclock right ? maybe above 2200 mhz in boost .
What do you think , it's ok the overclock or it's shit ?

Thank you .

They are good enough for initial testing.
But than you need to play your actual games.
For example I had no problem with Heaven and Furmark, but in crysis 3 i had annoying artifacts, so i had to go from 2100 to ~2040-2050 to make it stable.

And forget about 2200. you are not going to reach stable 2200
And there is not much need in such clock.
Actually everything around 2000 is awesome.
