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.

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

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?

 

[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.

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 :/

 

[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

 

[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.

 

[savagesam117]

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.

I fixed it!!! Turns out there was a big windows update that needed doing. Went for it, updated drivers as it didn't make things any better going back and now it's perfect, Black Ops 3 loads and plays. AC has no problems at all. I'm now a happy camper!

No not a single coolant leak.

That's good news enjoy
I would just like to use this moment to say just how easy it is to blame AMD and there drivers etc

You love to back up the drivers don't you

I didn't think It was drivers at all, more my hardware as it was causing BSOD's and stuff. Hopefully the new drivers will just boost fps even more. Not a single problem with AMD drivers when i've used them.

I was sooo close to reinstalling windows too.

Thanks everyone for your help too
