Sitting at desktop and no apps running it's sitting at 3D clocks. None of my settings were changed and my specs are in the description.
Using driver 304.48
 
Using precision and looking at the info tab it says no 3D process detected.
 
Help?

Nvidia drivers for the 200-500 series do not support downclocking when running multi-monitor setups.  If you are running in SLI only the secondary card will downclock.
 
Unsure if this is true with the 600 series cards.
 

Ok...well thats good to know. I just wanted that explained and to make sure it wasn't a bug or anything.
 
Temps are still great and two monitors is awesome!

Ya, I wish the my 560Ti would downclock in Windows with my two screens.
Not sure why it does this, but it's no big deal.

It won't down clock to low power state but it should clock down to 405Hz when running multiple monitors.
 
Try reinstalling the driver just be sure to select clean install when you do it.

Did that with 304.48 and no dice
Recommended driver to try? I wouldn't have a problem rolling or forth to any of them...I've never hit any of the problems people talk about with their drivers so 9/10 times I'm always on latest beta.
 
Should I be using the 296.xx or whatever it was then?

When I was running 470's with 2 monitors, they would clock down to 405, but since going to the 500's, they will always run at full clock speeds.  Don't know for sure if it was the 400 series cards or the drivers from back then, but that was the case.

Same here, the card will never clock down with two monitors. However, this only happens when the monitors run different resolutions. If both monitors are the same if should clock all the way down to 51MHz.

Even running 2 monitors with the same res will not allow clocks to download to idle (50mhz).  Not on 500 series cards and earlier.  At least it never has for me with all the different cards I've used from 9000 series on up.  I can't say about the 600 series cards.

Looking around the web it seems you are correct and by the look of things it appears to be a hardware limitation. I run two very different displays so I cannot comment on it but I have had no problems with inspectors multi display power saver feature to keep the cards at 51mhz.
Anyone wanting to try it out can check out the following page where it also shows how to delay inspector at boot in case it loads before oc apps like ab and precision

Actually the card will go to idle if the 2 monitors are using the same res on a 500 series card,
I'm using a gtx580 and 2 monitors with a 1920x1200 res.

That's interesting.  I've been running monitors with same res for years now and without using something to force them to downclock to 50mhz, I've never seen it do that if both monitors are running.  If I run 2 monitors on my 580's, the clocks stay at full clock speed.  When I run 2 monitors on my 470, the clocks will drop to 405mhz, but never to 50mhz.  All my monitors are 1920 x 1080.

I'll have to check that out...thanks for the info.

That's very odd, you're not forcing full power through nvidia control panel?
Because i can see the clock go to 51 mhz when i'm not doing anything.

What I did was connect my second monitor to the DVI out on my Z68 motherboard and now my GTX 460 downclocks

No, it's set to adaptive.  It's also a known hardware limitation by Nvidia's own admission by design.

Here's a pic of a page from Nvidia's release notes of drivers.

Yea, i know about the limitation, i had it on my old gtx280 when i had 2 monitors with a different resolution.
But when i got 2 monitors with the same resolution and a gtx580, the card always clocked itself down to idle.
