Titan Z not running in SLI

Hi everyone,

 

Ever since the latest Nvidia driver, it seems my Titan Z can only run off one of the 2 GPUs. I can't see the SLI option in the GeForce control panel. However, I still see 2 Titan Z listings in device manager which says to me that it's likely to be a driver issue perhaps.

 

Just wondering if anyone has any idea on how I could try to fix this?

WTF you have two titan z's?

A titan z is one card, with 2 graphics chips on it.

2 cores on one pcb.

do both of them show up in the nvidia control panel, or only in device manager?

 

You can always revert drivers as a temporary fix, but it does seem weird...

I never knew someone actually owned a Titan Z...

But try an older driver, did that allow SLI?

He's running duel 980's i believe, unless the bastard upgraded again to X's. Pretty sure before the 980's he was running dual Titans, not a titanZ.

Hmm... device manager shows 2 TITAN Z entries (which is normal) but EVGA Precision X only shows 1. 

 

It seems like the only thing I can do is to revert to a previous driver, which I'm quite reluctant to do. 

 

Anyone else have any ideas?

The windows device manager is showing the correct entry - a dual gpu card should show up as two separate entries.

I've had a couple issues with the latest whql GeForce drivers but my cards run fine seemingly otherwise so I'll just wait till the next one rolls around and hope it fixes them - not the most scientific approach I know.

At least try and revert to an older driver that you can confirm works with the SLI option so you can eliminate one possible cause - you don't have to keep using it thereafter if you don't want to.

Okay, I reverted back to 347.88 and I have SLI again. This is so weird. I guess I'll keep this version until the next driver comes out.

 

I guess this is sort of expected since there aren't many Titan Zs out in the wild...
