My Bus Interface is mysteriously low?

post #1 of 123
Thread Starter 
PCI-E 3.0 x 16 @ x8 3.0 (at times showing even @ x8 1.1)

Why is this happening and how do I fix it? Is it a problem with my cards or a problem with my mobo?

yes as it should, under load with sli you will be running PCI-E 3.0 x16 @ x8 3.0 meaning each card is sharing the lanes. I.E why you have x8. when your cards are idling they will kick in the powersaving feature is why you get the @ x8 1.1.

Go to windows start button,
go to the search box
type in power options
Click show other profiles
select high performance

Should fix your problem

Also just noticed your cards are not hitting 99% usage.

just ran it to see if mine did and 99% for every test.

why do you think the usage isnt 99%?

I changed Windows Power Options to High Performance. I used Driver Fusion to sweep the beta driver and install 310.90 ran the test again but still low graphics score:



I also just noticed that both my cards are idling at 1006MHz

Because your picture shows it bouncing all over. look at the difference between mine and yours.


My card hits 99% and stays there yours looks like it spikes there then drops
1:Try taking 1 card out and re running it for me please see if usage stays constant

2:Go into safe mode then go to c: drive delete nvidia folder then go to program files delete the nvidia folder then go to program filesx86 delete nvidia folder

Now boot back to norm windows and re run the installer pick custom pick do a clean install report back

Yes I know how you can tell that my usage isnt 99%. I was asking Why.... Why is my usage not 99%?

And when you say do a clean install, do you mean a clean install of the driver? or something else O.o
