Graphics card crashes

[Pale Shaza]

Hi, my graphics card (HD6850 msi cyclone oc) always crashes. Has since I got it a few months ago. I've ruled everything out including psu, driver, bios, chipsets, os etc...

It doesn't crash during games (It used to, but seems to be alright now that I underclock it. It can usually pass benchmarks no problem. The other day I ran heaven, it crashed the first time immediately but then when I rebooted it ran for half an hour straight.

It does commonly crash when streaming video's or watching downloaded movies etc... Not always, about 20% of the time, also if it doesn't crash the first time, it generally won't crash unless it powers down and powers back up.

Sometimes it'll just crash randomly, I might come back and it'll have died or I might be using ms access or something and I'll click a button and it'll just die.

My old card (HD 4650) worked fine, completely stable.


System specs:
Motherboard: Gigabyte EX58-UD3R
Processor: Intel core i7 920 @ 2.67Ghz
Memory: DDR3 6GB (corsair tri channel)
power: Cool Master gold 1200W (upgraded from corsair TX650W, it didn't solve the problem)
Graphics Card: MSI Radeon hd 6850 cyclone power edition (OC)

No it's not. When it crashes it looks like this:

I have to force restart the computer to get it back.

I assume you have done a complete reinstall of vga drivers? Another thing to check is the event viewer to see what problems are reported there. That will give a little more info.

I've done all of that and checked the event viewer etc... no help there.

Yes, I think that aswell about the oc, but it still crashes sometimes underclocked.

I'd say RMA it, problem is they'll run it through benchmarks and if they don't get the same problem they'll make you pay to get it back. So you've been sold a dodgy product and ur basically boned.

Yes, it's already happened once with this card a few weeks ago. I've got a new RMA and they're going to send it back to MSI when they get it. I just want to know what the problem probably is.

How come some can handle the pre oc and others can't i.e. my one? My card runs at a pretty low temperature (< 55C full load I think it was).

Yea, that's interesting. Using speedfan my gpu when not under load is running at 33C and that's with the computer being on for the last few hours.

I'll try doing what you've done with the fan to see if that solves it.

These are the temperatures speedfan is giving me, I don't know what most of them mean, hopefully somebody can enlighten me:

Temp1: 25C
Temp2: 44C
Temp3: 43C
Temp: 2C
HD0: 27C
GPU: 33C
Core 0: 49C
Core 1: 47C
Core 2: 48C

It also says that Fan1 is running at 1116 RPM and GPU fan is running at 1309RPM. It also says Speed 01, 02 and 03 are running at 100% and 04 is at 0%.
