Hi guys,
Having a bit of a bizarre problem. Have been running my system with a single GTX770 for about 3/4 months without a problem. Decided to add a second recently, got hold of another of exactly the same type, and also took the opportunity to upgrade the power supply and RAM while I was in there.
The computer boots and plays games fine with SLI disabled. Both cards are clearly getting power (the fans are spinning at the cards are glowing blue), and they are being recognised (the second card appears to be automatically assigned to PhysX duties). However, whenever I try to set the SLI settings to "Maximise 3d Performance", the PC immediately bluescreens.
Specs:
Asus P8P67 PRO (Rev 1) + Onboard Sound
8GB G.Skill DDR3 PC3-12800
i5 2500k (Sandy Bridge)
250GB Samsung SSD
1TB WD HDD
2 x MSI Lightning GTX 770 2GB
Corsair RM850 850W PSU
Windows 7 64bit Ultimate
Things I have tried so far:
- Removing Nvidia drivers, cleaning with Driversweeper, and reinstalling
- Reinstalling Nvidia drivers without GeForce experience
- Updating the BIOS on my motherboard to the latest 2xxx revision (I cannot update to the 3xxx revision for some reason, the flash utility says it's incompatible)
- Switching the positions of the cards
- Using a different SLI bridge
- Attaching the SLI bridge to a different point on the cards (seems there are two possible places it can go)
I would really appreciate help if anyone has any ideas.
Thanks,
