SLI Hell ....

Hi,

Just received my second GTX 770 Direct CUII OC.

Now, in game I am having major issues with the setup, games keep crashing (BF4 and Ghost). After a while my game just freeze's and them I loose both monitors, hard reboot. I have a 10c difference between the 2 cards but after reading it's quite normal. The hottest card goes up to 69c... not enough to make it crash.

PC spec's are in sig.

What I tried to date:

- Synch both card's with GPU Tweak
- Swap card's
- Changed the SLI bridge
- Unclocked both card's and synch them with GPU Tweak
- Updated the VBIOS on both card's

Any help would be great 🙂

Thanks

Mad

Hey mate, try booting up in Safe Mode and uninstall the drivers, reboot and install them again 🙂

Yes, I'd echo what Myk said. Get something like DriverFusion and remove all things Nvidia in safe mode and then clean install drivers.

Also don't synch the cards in GPU tweak. The drivers allow the cards to boost to different clocks with out stuttering etc. so let GPU boost take care of running each card to its max. I presume you are not OCing them past the factory OC?

Work out which is the strongest card individually and make sure the new one by itself runs to spec etc. and see how far it OCs. If you sync the cards you have to be syncing to the lower card not the higher.

Make the stronger card the first card.

Nothing worked so I unclocked my cpu from 4.5 to 4.0 and all look's ok now, 2-3 games of Ghost and no crashes... Bummer I have to do this 😞

Hmm that's lump off the CPU OC....but running more GPUs puts more stress on CPU so you'll have to work back up slowly again raising Vcore and maybe VCCSA and VTT....?

Battlefield 4 is a pretty cpu intensive game you might need up to 1.4 vcore for 4.5 Ghz. Could also be your psu, for one gtx 770 a 600 watt power supply is recommended, figure in the second card and overclocking you're pushing your corsair HX850 to the limit.

My UPS shows only a 700 watts power consumption in game but Ill order a HX1050 just to be safe.

My vcore was at 1.34 and stable, never crashed on any bench and game. Maybe you are right , Ill bump up the vcore to see what happens.

Even with my cpu at stock speed ,still crashes. I tried everything, ran both cards in non sli and both of them work, but in sli it just wont.
