2 GPU set up for Vray RT

Admin can delete this.. Our IT guy didn't plug the power cable in to the Quadro....

Hello all,

I'm asking here because it feels like it's the best place to get an answer so sorry if it's in the wrong place.

I just got an EVGA FTW GTX 1080 yesterday and I'm trying to run it in unison with my K5000 Quadro. I want to keep the K5K for display and the 1080 for rendering. Currently I'm facing the following issues:

1. Upon starting my PC, it seems to be defaulting to the 1080 as my main display output. Plugging my monitor(s) in to the K5K gives me a blank screen but switching it to the 1080 gives me a display.
2. If I install the drivers for both cards, I always have one card that gets stopped in the device manager and Vray RT does not see the GPU that has been stopped. However, in GPU-Z both cards appear.

I was always told you should always get rid of the old gfx drivers before installing a new card so how do I install two sets of drivers for two different cards without conflict?

The machine I'm using has a Supermicro X9DAi mobo with 2x Xeon 2680 v2's and 64gb of ram.

Thanks

Hello AC5L4T3R,

I use similar setting, or almost.
For using K500 for display, best is plug it on your first PCI-E Port, but, when you have one recent card with one old card better is plugging recent @ first PCI-E.

Which driver you use ? Last 372.54 are not suitable, best is Hot Fixed 368.95.
Don't use current Quadro driver bundle, GPU 1080 is actually not recognized with this driver, we need to wait NVIDIA release new QUADRO P6000 & P5000.

Great thanks. Currently I have them in slots 3 and 5 as I have a network card in slot 1. Also slot 1 would put the fans of the GPU pretty much 1-2mm away from the bottom of the case. It's a tight fit.

Yeah I have the 372.54 so I'll try the 368.95.
