2x GTX 660Ti's, only one of them seems to be taking the load.

[Mysteryman2000]

I decided to do a few benchmark tests after installing my second video card and it turns out only 1 of the video cards is taking on the load. The other one remains at 0%. I'm new to sli, was there some sort of driver I needed to run both?

Did you happen to enable the SLI ? Most people think its just plug in go thats why I ask.

 

[Mysteryman2000]

I believe so, it is under Configure Sli, Surround, Physx tab on the panal. It says sli enabled and It is set for maximum 3d performance.

Do you have the SLI bridge connected ?

 

[hapkido]

You'll also need to run applications full-screen (not full-screen windowed).

 

[Mysteryman2000]

Yes the bridge is connected. Though there is 2 slots for the bridge do I need one on both?

 

[redeemer]

so which benchmark software are you using?? Try Unigine and see if you get SLI utilization

 

[Mysteryman2000]

Alright, so far I have been using the Kombuster from MSI afterburner for benchmarking.

No one bridge will do you don't need to use multiple bridge that is for tri sli.

 

[Mysteryman2000]

Here is something interesting I noticed though. For the PhysX setting it is set to automatic, and it has the second card chosen for the job. Should PhysX be choosen for the second card or does that not matter.

 

[bigshootr8]

It really doesn't matter much. It will be handled by a GPU. Whether its 1 or 2 doesn't really matter. I had that happen with me with my two 560Ti's I had before I sold them. You are golden there.

 

[Mysteryman2000]

Alright, I have the benchmark from unigine.

Here is the scores, it doesn't say anything about sli.

You might want to do a little bit of a OC. Since your running SLI its somthing thats recommended.

 

[Mysteryman2000]

Overclock the cards? How much should I do?

 

[bigshootr8]

I believe he means the CPU. You do not need to overclock the graphics card. Also without knowing your cooler its hard to tell how far you could go. Are you using a stock cooler.

 

[abCasPeRR]

Overclock the cards? How much should I do?

No the CPU, you might not need to OC it but running those 2 card on default stocks could cause a bottleneck.

 

[bigshootr8]

That is what I thought you meant but without knowing his cooling situation and his cpu temps it's hard to really advise that. I would say if you could get to 4.2/4.4 ghz you would be in a better situation.

Well of course not I wouldnt recommend even a slight OC on even stock cooling. I was just bringing that point out.
