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?

BTW at this point the pc is dead, it needs a power reset and comes back fine..

Yeap i get that too, happens every now and then. I just reboot and all is well. Had that happen on my xfx 5870 and my sapphire 5970

oh, ok, as long as it is meant to happen then :lol:

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?

ARGH, just had to retype the whole reply as my login timed out :( This reply will be briefer..

Yes, there are the 8 and 6 pin power connected.

Drivers are the ati 8.663 hemlock beta, the only ones available from ati for the 5970.

I have had it happen in dirt 2 , rfactor and il2. The only games loaded so far.

The setup is a i7 920 clocked to 3.7, runs fine with prime95 for 40 mins, at 70deg C.

Its all in a coolermaster 932 HAF, thats got 3x 200mm fans, a 150mm fan as well as the two 120mm fans on the megahalems heatsink.

Right now at idle the gpu is 42 deg C, I cant load anything right now but it wasnt getting anywhere near 100C under load. I cant quite remember what it was though, in the 70's maybe.


Thanks.

I have a Corsair HX450W and had this problem a lil while ago as well while playing. Nothing overclocked and I have a 5850 with 2 monitors. About to hook up a 3rd with EyeFinity. Will this have an impact on my powersupply? Do I need to worry about anything? Never had any other problems and only happened once so I might be just paranoid, just checking though.

I loaded up the MSI afterburner tool, not for the purpose of overclocking but because it has all the graphs for load etc..

I played around with the unigine benchmark and dirt 2. Noticed something interesting..

GPU 2 would go to ~100% gpu temp for cpu2 would be ~50degress and gpu1 a little less.

GPU 1 was not running at all with dirt or unigine?? It's like crossfire is not enabled and there is no option in the catalyst drivers to enable it like there was for my 4870.. another mystery? I would imagine that the msi tool is compatible enough with my HIS to work..

I hope only one gpu is running and I get the other one to go as well, more FPS :)

FYI, I was just at the guru3d forum and there is a big thread about this. It happens to a lot of people with no obvious common reason.

It can happen after 5 minutes or 5 hours, quite random but common enough on these cards.. Bit of a bugger. Now to find out if I am only running 1 GPU or if the software only reports 1 gpu running but both are.

I see in the catalyst tab it show only activity on one gpu and not two as well but in my searching I haven't found this problem..

OK, I may have figured it out..

A number of guys who had this problem with an asus motherboard fixed it with a bios upgrade. I wasn't on the latest so I upgraded. As it is random when it happens I decided to overclock as that would always give me a problem.. I was able to this time..

It was running from stock 725/1000 to 850/1100 overclocked. I cant change it much more without getting the problem though. I was unable to get this far in the past without a very quick gray screen.

I suspect I cant get higher because I dont have a util to overvolt the memory but I am happy anyway.

Running the unigine benchmark the gpu's get to ~62 deg C

Now, if I only had two of these cards and a game that really looked like that demo then I would be happy! :)

BAH, I seem to be finding every problem you can with this card..

It seems that crossfire was not working. It has been identified as a problem with dirt2 at least. There was a hotfix which I downloaded..

Now I get the BSOD on win 7 every time I try an create my eyefinity group.. One monitor seems ok although I havet tried to run dirt and see if I get crossfire on the single monitor. Academic if I do because I want Three!

Interesting about the crossfire not working. It's the catalyst AI. Everyone says turn it off and it seems to turn of crossfire as well.

One it's back on then crossfire also works with framerates going up a lot.. Everything needs to be learnt the hard way with this card..

Crossfire is not supported in Eyefinity yet!

I am running the 5970 which does supported eyefinity for some games.

Also, I was having the problem of crossfire not running when I did not have an eyefinity group set up, e.g. testing with benchmarks like unigine.
