Crossfire Problems.

[savagesam117]

I'm new to this crossfire business. When I bought the cards, I tested them both, on their own and together no problems at all.

I've just changed my loop to acrylic tubing, popped both cards into the loop and now i've got some problems.

I was happily playing AC, crossfire enabled, working fine and then went out to get breakfast, came back put it back on and now it'll play for ten minutes or so and then crash, in the manner if the overclock on the cards was too high but they are at stock.

Try to load up Black Ops 3 and i'm displayed with a red screen straight away. GTA V crash in the same manor as AC.

Any other game i've tried plays fine, BF4, Dirt Rally, Tomb Raider.

Could be hardware/connection problem so take one card out or remove the crossfire bridge and test with single card. It might be as simple as removing replacing the crossfire bridge or cards though since I had a similar problem once and thats what seemed to cure it.

edit: if some games are working then maybe some other problem. Have you got the crossfire logo enabled to check if the game is running it crossfire mode?

The Red screen tells me your cpu overclock/memory might not be stable.

 

[shankly1985]

Red screen can happen from unstable cpu overclocking, any cpu overclocking?

It did have but I took it off and now everything is stock as that was the first thing I thought of. Only got my xmp profile at 2400mhz for the ram. Could this play a part?

 

[This never ends well]

Try everything at stock including ram.

Has the 7970's had a modded bios and you may need to up the power limit.

Is ur powersupply enough?

I know i needed at least 850w for xfire 290x's and 4790k.

 

[savagesam117]

I'll try the ram.

I've used a couple of voltage calculators and they say it should only pull 600w when under load, the PSU is just under a year old and not been used for anything major at all.

Psu is fine my fx 8350 @4.8 with two 7950's @1050/1400 only pull 560 watts from the wall.

Red screen from my 7970 days sounds live not enough volts to gpu.

If afterburner installed set power limit to full (+20%) iirc and set your gpu clock to 1000/1600 and see how you get on.

Edit just seen you been playing with your loop mite have changed the bios switch on the card. Make sure they both to the left and try again. If same try both to right

I didn't even realise these cards had bios switches, they were odd. I'll have another go!

EDIT:

Now i'm not getting any red screen just "Page fault in nonpaged area" I've ran chkdsk and everything came back okay. I think my RAM is dead as it was causing me problems yesterday too :/

 

[This never ends well]

Bios switch to the left is protected, which is stock.
Switch on the right can be flashed.

 

[savagesam117]

Ah right. Well I put my brothers ram in my PC. And now it's working but the second gpu is fluctuating between 0-30% usage

use DDU to uninstall drivers and start afresh.

What game are you trying to play.

Run heaven or valley and see if you got 99% usage.

 

[NoobCannon]

could still be a faulty/corrupt bios.

clean install drivers first using DDU and then after making sure the power limit is at +20 try again.

 

[savagesam117]

I nuked the drivers, reinstalled 15.11.1.

So I run Valley/Heaven etc and get 99% usage on both cards, woo!

Older games as above, working fine.

Trying to play AC Syndicate. Works great high usage on both cards, crashes about 10 minutes in.

Black Ops 3, crash as soon as I start it.

Both games work fine on both cards on their own, no crashes and everything is fine. I know both games are a bit dodgy on profiles at the moment but I wouldn't expect it to crash?

Power limit is set.

I'm going to try a driver roll back and see if that changes anything.

 

[This never ends well]

Try 15.11, on black ops what settings are you using, try playing on high.

Yeah I'm going to roll back in a minute. Mate, it won't even load with crossfire enabled. Plays fine with a single card.

Ok load the game with just one card and set all the settings to low, then try with both cards if it still does not load, verify game with steam.
