Can i match 2D and 3D core clock speeds?

[xMax]

So your thinking to yourself "Why would he want to overclock his 2D core clock speed?".

Well, im not entirely certain, but what i do know is that i dont play any games on my computer as i have not once heard my video card fan come on. All im using my computer for is full screen playback of AVI animations in windows media player, which i believe uses the 2D hardware on the video card more than the 3D, even if WMP uses DirectX hardware acceleration.

But why i would want WMP to run faster you might ask? Well, for some reason, there seems to be this bizzare rectangular tearing that keeps occuring at the top right hand corner of my screen when running any Media Player with any DirectX settings. So im thinking that a 2D overclocking may fix this rectangular screen tearing problem.

Natually, though, im questioning as to wether the 2D is designed to run at such high core and memory clock speeds, since if its not, then i could easily burn my card.

I know that my best bet is to use Coolbits or Rivatuner, since they seem to be the best utilities for overclocking. If i had to pick, i would go for Coolbits for its ease of use and simplified interface.

So thats my situation. I never use 3D, so why not run my 2D core and memory clock speeds at the same speed that my 3D core and memory clock speeds are running now.

What do you guys think?

It doesn't matter.

I run them both the same because sometimes I find that the 3d clock speed doesn't always kick in during a 3d app. So with both the same it's kinda hard for it to use the wrong clock speed. I'm use heavily OC'ed 7900GT's so if the 3d and 2d clockspeed have such a large difference, you'd notice it in a game.

And for your kind of OCing just use Coolbits. Simple and easy to use and built in. Your not really shooting for a high OC (like I am) so just use Coolbits. Also, WMP doesn't use the hardware rendering (using your video cards) unless you tell it too. Go to Tools->Options->Performance->Click on Advanced on the bottom->then under video mixing renderer (top left) select the high quality mode and it should use hardware rendering. So the bizzare rectangular tearing shoudln't be a video card problem unless you already have it running in hardware rendering mode, and raising the clocks, I don't think that would help. If anything raising the clocks would make it worse, but I really don't think that it's a video card or video card clock problem.

Try playing the clip in a different media player like Media Player Classic. That uses a different renderer, also you can try using Nvidia Decoder and ffdshow. (thats a whole nother story, maby you can PM me or just ask me/others here).

Conclusion:
-Raising clocks will most likely not help with problem. You can still do it and it won't affect anything
-Problem is most likely with the renderer. Try using the High Quality mode in WMP
-If that fails, use something like Media Player Classic.
-You can also try using Media Player Classic with Nvidia Decoder and ffdshow.

Thanks for the very detailed reply wizboy11.

Before beginning, i will tell you that i have tried just about every type of rendering method in every major media player i could find to fix the problem, but without avail. Some rendering schemes did fix it, but they introduced a worse problem, like a different type of tearing that was worse than the rectangular one. I tried WMP Classic, the one with so many features, ZoomPlayer, WMP10, and a few others, but all were the same. I also tried the Nvidia Decoder and the ffdshow, but both didn't change anything.

And i asked a bunch of users here at the Anandtech forum to see if the problem has to do with the video card or some other component. Sure enough, other people had the same problem, and the only common variable was the Nvidia Gefore cards. People with completely different specs had the same problem.

But i don't want to reopen this whole subject since i don't think there is a fix to this problem, as i would agree with you about the 2D overclocking not fixing the problem either.

Nonetheless, with your card having both 2D and 3D set at the same core clock speeds, and with this not being a problem by any means, then im going to overclock my 2D to the same speed as my 3D. It only makes sense when i dont even use 3D in any way shape or form.

But i have to ask: "what about the memory clock speed? Can i run the 2D memory clock speeds at the same speed that my 3D memory is currently running on?"

I'm assuming the answer is yes, but i just have to make sure.

Thanks again for your very informative reply wizboy.

You have a 7900GTX and you never use 3d? :|

 

[xMax]

I didn't have a choice. I got the top of the line of every component inside my computer. So it only makes sense to get the 7900GTX, even though i don't need it.

Sure, its a waist of money, but considering that i must sell my computer when im done with it, which is hopefully pretty soon, then i will have an easier time selling it with the 7900GTX than some low end card.

Didn't want to quote it, little to long

Go ahead and change the 2d to 3d speeds, and the memory clock is always the same. So if you set it to (just an example) 900mhz in 2d mode, then it will be 900mhz in 3d mode. And then if you change it again in 3d mode to 800mhz, 2d mode will change too. So for memory clock speed, it doesn't matter which mode your in, it changes both.

For the core speed just bump the 2d up to 3d clock speeds. Sometimes I find that after I exit out of the NV Control panel the 2d clock speeds go back to what they were so just open up the NV Control panel, change them again, and then apply (again...). Not sure why it does it (for me?) but it's been doing since I ever got a nvidia card and used coolbits (weird?).

I want you to try something else (just amuse me ). Follow my guide here (step are towards the bottom), then are #'ed so just follow the order. Install these XTreme-G 84.56.v2 Drivers. They are modified drivers (improved performance/IQ) so it does change some things that might help. I'm not sure if you've tried this already, but I'm just suggesting you try it cause 90% of the time, changing driver versions or using a modified driver like XG will make the problem(s) go away.

Edit: for the XG Driver link, just choose the first option on the page (called "Download XTreme-G 84.56.v2 Rev1" if your using XP. Choose the second of your using XPx64 and just ignore the last two for now)

It's almost a sin

 

[xMax]

Im gonna give all your suggestions a try wizboy. Starting with the XTreme-G Drivers.

If i don't manage to reply by this evening, then you will see a reply by tomorrow.

And yes, it is a sin not to be using 3D, but thats the way it is.

Ok, just be sure to use Driver Cleaner Pro. (or follow the guide, just incorperate the link I gave your somewere in the guide), you get it right? (cause I'm confused )

 

[xMax]

I did everything you said but the rectangular tearing problem did not go away.

So i just give up on this nonsense of a problem

Of course, i still like the higher 2D clock settings. So i got something out of this thread.

Thanks wizboy11
