7950 Crossfire Problem *Updated*

post #1 of 5
Thread Starter 
*** Update ***
Got through a Heaven run just fine.. No idea what is going on, 3DMark makes it crash along with Kombustor still.

Hey guys,

Basically I've got a second 7950 that I was given. Adding the card to my system it ran fine for BF3 (Yes, it's CPU bottlenecked apparently)

In Mafia II it crashed after about 2 hours gameplay, well by "Crashing" i mean a hard reset.
Testing this further it turns out that MSI Kombustor crashes on "test" I don't even get to see anything it just resets. So far I've tested.

Proper 6x Pin: I was using a molex - 6 pin and borrowed the cable off a friend who has the same PSU (I lent mine to a friend for a bit)
Downclocking the CPU/RAM: Had no effect whatsoever (from 4.6 to 3.4) - Possible rule out of PSU issue?
Add more voltage: Custard suggested this one, but to no avail running at 1.25v I got a hard reset
Another CFX Bridge: They were different brands?
Deleting all the drivers: Manually did this according to This guide and went to the 13.2 Betas which did the same thing.
Tried this guide: Here
Tried the cards individually: I've had the HIS one for 6 months and had no problems, the 7950 was put in a friends PC before it. To test nothing has happened in transit I disabled CFX and ran them individually to have no problems. To change card I changed the DVI over and used kombustor on a single card.
Tried Furmark instead of kombustor: Nothing
Cards both at 900MHz: One is stock at 900MHz, the other is stock at 925 and they both like to run at 925MHz when they're in CFX.
Re-installed MSI AB:

The only logical thing left to try is another PSU... Or take the cards out and put them in someone else's PC.
Does anyone have any other ideas/had any problems similar to mine?

ANY help is greatly appreciated! I just want to play some games..

EDIT: Just tried disabling ULPS (I thought of this one myself tongue.gif)

You mention a friend with a computer - the only thing to test really is the Motherboard + CPU combo/PSU, and that can be done in one test by putting the cards in his system on Crossfire.
I guess pull one for now, and ask him if he has any free time to run Kumbustor on the cards at his for you?

I've got quite a few friends who'd let me test the cards in, I guess that's just what I'll have to do.. For now i'm trying to disable ULPS but from what I remember that fixes BSOD related problems not shutdowns.

A rep was given wink.gif

downclock the cards to 800mhz or less.
if that works your psu isnt enough to feed the cards.
and ulps is one of those things that mess with oc.

Thanks! I ended up formatting to find out that it's still there! So it must be a problem with the PSU afterall! I'm going to get a ~850W unit soon. Probably like a Silverstone Strider or maybe a Corsair 760i or something.
