I have seen this twice now, once after leaving dirt 2 in replay mode for a while and today after loading blackshark (which btw only lets me go to 4800x1200).

It happens on the left and right monitors I see these lines and the center monitor is just black. the monitor pluggen in to the DP is one of the two with lines. Anyone seen this before? the card a 5970 is not clocked but the computer is and has run fine at 3.7 with prime 95 tests. it gets to about 65deg..

Any ideas?

I get it too. It's rare, but really annoying when it does happen. Driver issue I assume (no overclocking here).

What your seeing is what happens when the GPU gets too hot!

I always use around 45% to 50% maual fan speed control before going into a game.

Setting up profiles makes it a snap to change fan speeds based on what your going to do.

As for the autofan control it's more tuned to being quiet then functional.

Hi Deke, it might happen when you overheat but it isn't the only time.

Just now I was trying to tweak my IL2 set up. I have been making minor changes then going in to IL2, running a track and checking the FPS.

The last one I did was turn ON AA to 4x. I played a track and within a few seconds it happened. I cant believe that < 4 seconds the card went from 54 deg C to overheating. The fan is on 40% manual.

There is certainly some other reason in my case why it happens.

Thanks,

What power supply are you running? Sounds more like a power issue from what you describe, if it can shut down in 4 seconds.

Hi Gilly, it's a new machine and they supplied me with a corsair hx650. The 5970 and a xi-fi titanium are the only things on the MB.

It's perhaps on the lower side of what I see people using but it should do the job considering there is no clocking involved. I think?

It is on the low side in numbers terms, but not in output terms. The Corsair units are generally very reliable and solid. I would discount that as a problem for the moment.

It's also 52A @ 12v single rail, so it's not like swapping which plug feeds what will sort the problem. The overheating issue is possible. There are (IIRC) 9 voltage regs on the card, 3 in the middle and 6 at the back, it's possible they are very warm, apparently the cooling for the 3 in the middle is shit...

Do any other games cause the same thing to happen? And what drivers are you running? What CPU and what motherboard?

EDIT: Just to make sure, there is 1x 8 pin PCI-e plug connected and 1x 6 pin PCI-e plug for power connected?
