Help with overclocking!

[I am a teapot]

Hello all! I'm trying to get my 980ti on a stable overclock and would REALLY like to hit 1500Mhz. My ASIC quality is 79.8% according to GPUZ, and I'm using a hybrid cooler in push/pull so I figured this would be easy. However I am running into numerous issues and have a ton of questions.

 

The overclock in question was on the following settings in afterburner:

- +55 core voltage

- 110 max power/91°C thermal limit

- +120MHz core clock

- +300MHz memory clock

 

1) When I run heaven 4.0 with the overclock on and run the benchmark, it will crash 10 minutes or so in, despite the gpu not boosting to it's  max speed often. In response to this, j turned on the free camera and focused on a single demanding object (in my case, the pine tree) in order to force the card to boost to it's maximum speed as much as possible. While doing this, the card hit 99% usage and to constantly boosted to 1525MHz, and it remained stable for 30 minutes and never had any issues. Does anyone know why this is?

 

2) I ran wolfenstein the new order on ultra at 1440p with the same overclock as above on, and experienced no problems. In gpuz it showed the card constantly and consistently boosting to 1525MHz without exceeding 60C despite running for many hours at a time. However, as soon as I start Dishonored 2 the game immediately crashes in 5 minutes or so. What does this mean?

 

3) does anyone have any overclocking tips for me? I know about maxing out the power limit and thermal target, etc. But anything settings/sliders wise? I feel like there's just something I'm missing.

 

Thanks all for reading!! And thanks in advance for any comments

lower the clocks and voltages. also what is your username

You understand that Afterburner adds any applied offset you set to your existing GPU boost, right?

Yeah. GPU boost pushes the core clock to around 1380MHz.

Oh crap, you said 980ti and not 1080ti, I was really confused for a second.

 

Yeah 1,500Mhz for a 980ti is asking for a lot, the large majority of them will do around 1,450 before they get unstable. Try setting the Core offset to 100 and see what happens but even then I think your going to have to settle with around 80 to be 100% stable.

Yeah I've been seeing that around a lot :l 

 

Do you have any advice on applying voltage and what increments I should increase my core clock? 

 

What do you think the deal is with Wolfenstein boosting so high and not crashing?

Honestly, Maxwell & Pascal are both so efficient that overvolting has very little (if any) impact on clock speeds, that's partly the reason why Nvidia limit overvolting in BIOS on Pascal, its just not necessary. Your card will hit its limit before it runs out of juice.

 

I always do increments of +5 when OCing a GPU, some say push to fa then scale back until stable but I prefer to push from boost to instability, scale back 5 and leave it there. Its all a matter of preference really.

Ah I gotcha.

 

I've been able to get it to 1475MHz before without any power adjustments but I wanted to push it to 1500, since I've seen it before on other hybrids
