Periodic freezing with crossfire:

[Tacitus]

Hey everyone, so today I installed my second 290x and have been playing some games to test it out. Been playing the Witcher 2 again, and I'm in the third act and epilogue section, where periodically my PC has completely frozen. I'd not be too miffed normally if it was once in a while, but in one particular section it froze twice within 5 minutes, requiring PC restart each time.

 

I know crossfire is working, it has taken me from average 45 fps to 60 fps minimum (ultra settings, using VSR @ 3200x1800p), I'm really enjoying it, but this didn't ever happen when I had an Nvidia GPU (admittedly it was just one, and I got my 290xs together, so didn't really play much with just one).

 

Anyone know what might be causing it and how I can fix it?

Reinstall your drivers and double check the clock speeds ect.

It could be that the PSU can't output enough power with bronze efficiency, though a freeze would generally lead me to think unstable. Check both cards when in-game for power draw and clockspeed etc with afterburner/precisionX/your fave utility.

are there any errors in windows event viewer?

Reinstalled drivers just this morning, clock speeds have been stable @ 1050 all day, power consumption is a good 150W lower in TW2 than in something like DA:I

The PSU is fine, I'm using an energy measuring device as I wasn't sure about it either being a 750W PSU. But see above. TW2 was drawing from the wall no more than 500-520W.

 

are there any errors in windows event viewer?

 

How can I view this?

 

 

At any rate, I did get past it by disabling crossfire, then I saved the game, exited it, put CF back on, and finished the game.

How can I view this?
