Heavy Duty Rendering with Overclock

[HowKnows]

I want to buy either a 970 or 980ti,

but board parnters tend to overclock many of their own GPU's

But are they stable ?

I mean for like a 2 week day and night 100% work load, rendering with non-biased engines

 

And the problem with refernce design is it runs too hot, so i have to choose a board partner like EVGA or ASUS, etc.

Welcome to the Forum.

 

Yes, they must be stable if they're factory overclocked. Ensure that the rest of the system is stable and cool enough, with a redundant power supply.

They are as stable as the reference. If they are not stable you can RMA them.

Yeah, they say they are stable, but they test them for normal gaming workloads, so a max of 4 hours through. But i am speaking of 2 or 3 weeks at 100%, and 1 small mistake will crash the rendering.

It depends on who you buy them from, EVGA have access to the reference PCB, I think they also have a longer stress-test.

What are you doing that will take 2-3 weeks for a 980ti at full load?

I do Blender Cycles rendering with unbiased render engines (cycles). So it's lots of ray tracing with rendering a big scene or animation, takes ages since it is litterly photo realistic rendering, so it will compute a lot, even with a 980ti it will take a long time.

Normal rendering of that quality is done on GPU render farms but i don't own one, or have acess to one.

had my new gtx 970 gaming g1 rendering for about 3 days long with not much pause, and as we all know the gaming g1 is quite much overclocked in comparison to the reference one.  No problems at all

exact the same thing i do with mine, but what you have to know is that the 780 or 780 ti smashes the 970 or 980 in render times

render times with the same scene

- 780 ti: 4:20 min

- 780: 5:20 min

- 980: 5:42 min

- 970 gaming g1: 6:10 min

- 970 windforce: 6:20min

 

all of them are factory overclocked, but run stable since years or months

If your main concern is using a non-reference GPU you could buy a AIO cooler for the GPU.

that concern is not  justified. my gaming g1 runs under 100% load while rendering not over 60°C, thats wasted money to get a aio cooler.

Just check some websites with test of your favorite card.

I was talking about being concerned about using a non-reference PCB. Not non-reference cooler.

For how long was you rendering? @HowKnows are going to render 2-3 weeks straight.

[19_blackie_73]

https://www.youtube.com/channel/UCNfyeJXT4b1aTsPCErB7i4Qthese two things, first one took about three days (every day 15-17h rendering, 30°C outside, my room not much colder and still 60°C, the second one about the same, a little bit less) No problems occured, no blender crashes or anything else

you don't have to worry bout the stability of these most times slightly overclocks

First, I was also worried about factory overclocks, but this thing runs stable and cool and silent so I decided not to downclock this card (which you can do).

wow thats suprising. But i the 1gb more VRAM could make some diffrence.

And i might buy a 980 ti, which performs close to a Titan X, and i don;t know if a 780ti can still smash it. Also the 980 ti would have double the VRAM.

I will have to see how much VRAM i really need, so i can decide 780ti or 970. or just save more money for a 980ti

 

But thanks for informing me that factory overclocks are stable for months

no problem

you can contact me if you have your card, then i could send you the scene so we'll see how fast the 980 ti really is if you buy one

Yeah, 2 or 3 weeks straight

Coz rendering animation with complex shaders and lots of geomtry just takes long

Righ now my intel i5-3210M at 2.5 ghz takes 12 to 16 hours for 1 frame. and with the animation not even nearly finished i already got 400 frames

And the shaders are as effiecent as they can get

 

The GPU will be much faster than the CPU, but still it will take it's time.

i know:D that's the problem of cycles, but if it's finished it looks beautiful
