maybe this is a silly question but im new to this and had to ask. im running dual nvidia graphics cards that are SLI'd. when i look at my tasks it says its only using one nvidia gpu and under my account info its only listing the one 1gb card when im running 2 1gb cards. my actual question is it actually using both and not reporting it or if it isn't there a way i can make it use both so i can crunch faster?

my actual question is it actually using both ...

Check the GPU load and temperature for both GPUs with some tool

The app itself is detecting both:

i installed techpowerup gpuz and while i was crunching its saying only one of my cards has a load on it. is there a way to make them share or do i just not have my cards running right?

after looking at the gpuz a little closer i noticed that i appearently was tired when finishing the setup on my desktop cause i nver enabled SLI on the graphics cards lol.

thanks for the quick response and info. greatly appreciate it.

Try also SIV (the first link) - it shows much more info
