Re: [Xen-users] GTX 670 Tips?

That sounds like the PCI ID instability I was talking about. You cannot 
just remove the resistors. You have to either replace them or mod the 
firmware straps to compensate for the instability.
The device is detected as a GK104 by Linux, but the driver doesn't know 
device ID of 0x11af so it doesn't work. Nouveau is more tolerant of 
dodgy device IDs.
