Clockspeed on idle GPU jumps to max when I open a picture?
I just installed a second GTX570, and while monitoring everything from MSI Afterburner it looks like the voltage, clockspeed, and ram speed are all jumping up to max on the idle GPU anytime I open a simple picture in windows picture viewer (Windows7-64), and then it lowers back down to idle the second I close it.



Is this waste of power normal ?




Also, how should I have my dual monitors hooked up for the lowest total idle power usage? Right now I still have them both hooked up to the first GPU, should I move one over? (I ask because the first one doesn't downclock at idle since the monitors are different models)

I believe its normal, since any hardware will have a peek of performance when it starts its use, if after launch the picture the use back to normal, so no problem.

With more then one monitor the card never downclocks, so maybe if you put on the second monitor they downclock.

I didn't realize opening a jpg picture required two GTX570's at full power

It doesn't. As Sinfatus says, It's a 'bug' to do with having dual monitors (and may also be affected by SLI). On a single monitor setup like mine, both cards jump up to full speed when the image first opens but, after a second, the drivers realise it's only 2D and they drop back down. On dual monitor setups, this seems to not happen properly.

I thought nVidia had fixed this in later drivers, but maybe not.

Thank you for the reply. I'm wondering if I should move the second monitor to the secondary card...

This supposedly works as well, at least according to a few friends.
