GPU throttling down when playing Shadow of Mordor.

EVGA8800ULTRA · Oct 17, 2014

I'm having a weird issue with Shadow of Mordor that is not affecting any other game. Sometimes the card will downclock from 1300mhz to around 770ish which in turn causes the frames to drop. I tried to enable K-Boost as I know that would solve the problem but it's greyed out in MSI Afterburner and EVGA Precision X which I find odd because a few months ago it worked fine. Tried to disable SLI and it's still greyed out. Any solutions? 3x GTX780Ti is what I am currently running.

Your other PC parts?

Here you go.

Core i7 2700k
Asus Maximus V formula
Corsair AX1200i
16gb Corsair Vengeance

Like I said, it's like the game isn't taxing the system and downclocking itself.

Turn on V-Sync . Improve the airflow

EVGA8800ULTRA · Oct 17, 2014

V-Sync is on, better airflow won't help as the cards are running below 50c when playing.

I think it's lack of lanes in your CPU it only has 16 lanes. Enough for sharing between two GPU's with 8 each.

Power management mode : Prefer maximum performance , only for that game ?

EVGA8800ULTRA · Oct 17, 2014

The board runs at 8x 4x 4x which is perfectly fine. I can get other games to use 100% of all three cards. It's just this game that's doing it. I'd like to get K-Boost to enable and test that. Any suggestions for that?

Heh.. have not tried that. Yeah it's only this game.

SLI requires 8 lanes

You're no help at all and are calling me a liar. Sure I had to make a few tweaks using hypersli but it runs fine.

EVGA8800ULTRA · Oct 17, 2014

Thanks for that Rockie_. I don't know how I missed that but it worked out beautifully.

Never called you that.

When you turn on V-sync, you effectively turn on a FPS cap and as a result, will limit how much your GPU's work.

The game also does not support SLI out of the box. I'm told AFR 2 will work, if you manually set it in the control panel.

Yeah I know it is not supported at the moment. No need for SLI in this game, it runs at a constant 80-100fps.
