GPU Problem

**bogan** · 19th August 2013, 20:57

I needed a second GPU so I could do work at home, so figured a cheapy would be ok to put in with my main one.

I have a Asus GTX 680 DC2T (overclocked) and got an Asus GTX 650 Ti to go with. Problem is, whenever I try to do any work with it, it blue screens the whole computer.

Cuda stuff, physx stuff in games, or just plug a monitor into it, all have the same result.

Motherboard is an Asus P8Z77V, cpu is Ivy bridge 3770k. PCIE bus is x16 but both are running at x8. The new card works in an old computer, though I've yet to update the drivers on that, will do soon but doubtfull it will just be a driver issue as its a common card.

Any ideas?

install linux lulz.

O wait. That was the other guy.

Bios: disable apic lapic, anything that sounds like power management.
Set pcie to auto, or full x16
fuck with the interrupt reqs.

Drop resolution on both to minimum?

Turn off all the fancy?

Monitor motherboard temps?

Investigate the BSOD message, often it's actually very useful for troubleshooting.

Might be you're lacking in the PSU department. Also, you're not trying to run them in SLI right? Does the new card work in your PC if you remove the 680?

Currently doing the driver check in a spare comp, new drivers had the code 43, so am rolling back to previous nvidia drivers, standard vga driver works.

No not trying to SLI them, PSU is 800W, and is the same PSU I use in another comp with 2x 660 ti, so doubt that is a problem. Fingers crossed older drivers will sort it.
