My sli slowed way way down

post #1 of 11
Thread Starter 
Anyone know what's going on here my sli was running fine then out of no where it slowed way down, sometime's it worked good and sometime's didn't, if I plug just one in at a time they are fine, just like the sli part went out.
The sli is working, I have sli but it's way slow and it's getting worse 11fps when starting 3DMARK06 now.
I called the video card (7900GTX)maker they said it the motherboard and Asus say it's the card??

My system is only 6 weeks old.

My 3dmark score's
SLI was working 10,100 not OCed
SLI now 5400
But both single cards still gets 6700 even though sil is worse.
Oblivian was 45 to 60fps now 20 or less, one card gets 30fps

Ive tried reformating differn't drivers power is good 700W sli approved, Memory is good SLI approved.(TESTED both)

I searched the internet and this link has the same issue, I am not the only one with this problem but nobody knows what it is cards or the motherboard...

Same thing happened to me. After doing the following...the speed magically went back to full power:

Complete BIOS clear and re-configure
Complete uninstall of Nvidia drivers and reinstall

Hope this helps...it freaked me out when it happened to me

Did you change the SLI rendering mode?

Maybe you are in SLI Anti-Aliasing mode?

Edit: Or did you recently take that jumper off?

I've tried everything re did the BIOS reformated drives. same with the jumper on or off.
I called a local PC repair shop they want $65 to tell me what's wrong and it takes 3 days.
Not going to do that pretty sure it the motherboard or cards.

I found out whats causing this after talking to ASUS for the third time, you need to reinstall nvidia motherboard drivers leave off the SLI conector while updating the nvidia drivers, then install the latest card drivers then enable sli restart once then shutdown install the SLI conector start done.
It works now after messing around for the last 3 days
