If I overclock a NVIdia GTX 660 to say 800mhz GPU clock, will it stick if I'm not gaming?

What the topic states...



I ask because I just grabbed a Radeon 7870. Looks like a fantastic card, but the problem is I'm not gaming. I need to do some video scoring, and the GPU clock speed is throttling at 300mhz. My video playback is choppy because of this as my audio project gets large. And my DAW will not force the 7870 into "High Performance Mode" so it clocks up to anything above 300mhz.

I didn't realize video cards work this way. Are all of them like this?

Would I have better luck with a Nvidia card?



I'm a total noob. Trying to learn as I go. I have zero needs for gaming. Just film scoring.. and eventually maybe some editing. My software is Studio One v2, and it uses a Quicktime wrapper to play the video.


Please, please don't mention anything about video codecs, etc... i've been down that road. I just am looking for a video card that can handle anything I throw at it at this point really. The 7870 would be it... but i can't get the clock speed to stick at anything respectable, which I think is a software-ish limitation of Radeon. Is Nvidia the same way?

What do you mean by "video scoring"? It may be something CPU bound.

"Video scoring" is the art of producing music for picture. I take the video, produce music to it while the video is playing, so it can later be rendered together. For example... if I were to get a movie sent to me... i would want to do the music to certain scenes of it... i would load it up into my audio DAW software, view the picture, and create music to sync to it over the timeline.

And sorry I've been posting on this so much I forgot to include my specs.

i7 3820 (OC'ed to 4.5GHz)
ASUS P9X79 Pro
32 GB of RAM @1600mhz
Samsung Pro 128 GB ssd (OS)
San Disk Ultra Plus 256GB ssd (data, read only)
RME UCX audio interface


I don't think it's CPU related. Video is working fine if there isn't much audio load. However.. when the project gets large, the playback starts to get choppy. I really think it's related to the GPU clock sped being so low. With my older Radeon HD 5450, i remember the clock bein around 200mhz, and i can see an acutla improvement with this 7870 operating at 300mhz, so i'm condifent if i could get it to run at it's spec'd speed of around 1000mhz it should fix the issue.


So... back to the question. Is a NVidia card programmed to throttle the GPU speed automatically, the same way a Radeon card is? And only offer the higher clock speeds when forced to by an intense computer game?

I just really want to know if I should expect the same "throttling" from the NVidia cards. I'm having a tough time figuring this out in my internet searches.

This will help me decide if I should just return this 7870 and swap it for a GTX 660. I don't really care about which one is better than the other... as they should both be leagues better than my 5450 and should be more than enough graphics for my setup.

I don't really have the freedom to go back and forth to the store since I have a newborn at home. So i'm trying to avoid wasting time on the road away from home.

Open up task manager and check CPU usage while doing a video. I'm almost confident it's ran on the CPU only.

^if that's the case, a monkey wrench has been thrown in my entire operation lol

this is basically something every gpu does, it drops to 2D clocks when not running a 3D application, there is no problem solve between brands they both do it. its a powersave feature

That's what I was worried about.

Okay... that makes sense. thx.



So.. I'm reading more and now I'm not confident that Quicktime allows for GPU accerlation, which it seems like is needed for the graphics card to be used in this situation. I'm also going to try sync'ing with a program like Sony Vegas Pro or Adobe Premiere. Preferably Premiere since that's what my video guy uses. maybe the limitation is just the Quicktime wrapper?

Thoughts? (Sorry... I know this may seem like a big of a scattered question. It's something I've been going through for a few days now maybe. This is kind of scattered between a few different threads even)

Let me know if you need more backstory on what I'm trying to do here. I'm not sure if it's clear in this particular thread.
