I recently upgraded my GPU's to two GTX 650 TI's. They are both installed correctly and are functioning because im using monitor points from both. What im confused about is the Asus GPU tweak/ Monitor software says that my second card is under no load. It hovers arround 0-8%. I ran FurMark GPU stress test and got the same results.

Heres my system info:
Mobo- DX58S0
CPU-Intel core i7 940
Ram- 12 gigs of ddr3
GPU- GTX 650TI x2
OS- Windows 7

I'm really at a loss. My understanding was that the GPU load was related to the monitor the program was displayed on. But every test i run points to this not being the case.

Thanks in advance :-)

im a little surprised not a single person has anything to say on this issue. . .

Has anyone seen something like this happen at all?

Could be the monitoring software. Im not to familiar with NVIDIAs SLI setup, but I know with my crossfire, the primary card does most of the work, and it only shifts work to the second card when I start doing something demanding, like a video game. It could be that way with your SLI setup to, the primary card could be doing most of the work, and all the secondary card is doing is throwing the image out to the monitor, which under idle, wouldnt take much at all. What does it show when your doing something?

By the way, I apologize for the delayed response. This site is run by volunteers, all with different fields of expertise, and as you can see theres a lot of people who post questions here, so sometimes posts do fall through the cracks. It wasnt intentional, Im sure.

I'm not running the cards in SLI there both independent.

When i have a game or a heavy 3d program (like autocad maya) on any of my monitors the load is only taken up on one card.

Are you experiencing any performance issues when running programs on the secondary card? If not it may just be your monitoring software then-have you tried another monitoring program?

how do i test the second card if its under no load? should i remove the first one?

I ran multiple benchmark programs as well as games and 3d software no problem but im unable to get as much power out of the 2 cards as i should be able too.

take a program that runs a heavy load, such as a game, and play it on the monitor hooked onto the second card, and see what happens.

Im sorry i guess i wasnt clear with my previous posts. I've several heavy load 3d programs and games on each monitor and even several attempts at running stuff on every monitor with the same effect. The second GPU doesn't do anything.

Heres the question of the hour though, do you have any problems? stuttering frame rate or anything like that on the second monitors?

That, sometimes unfortuantly, happens when your running multiple cards that arnt directly linked in SLI or crossfire. NVIDIAs supposed to have 4 way monitor support in SLI, have you tried SLIing the cards and seeing if that fixes the problem?

No, it wouldnt, the GTX 650 should support 4 monitor support in SLI, which would have to use the ports on both cards. If the cards require a SLI bridge, install that, if not then just go into the NVIDIA control panel, select the SLI configuration page, and enable SLI technology, that should enable the SLI capabilities of your card. Beyond that, Im afraid is a bit beyond me-Im not to familiar with SLI technology, let me see if I can get someone in here who knows the proper settings.

Does your model of 650 require a bridge? Most of the models of 650s Im finding on newegg dont require it.
