Right ill start from the beggining.

I bought a 3870 x2,
I found that it was crashing when i was gaming. I thought it was a fan speed profile not working, which it still may be. I thought this because it was very quiet, and when it crashed, there was a no signal screen and a suddenly loud gpu fan.

I used rivatuner to control fan speed, couold hear hear the fan changing speeds but still getting crashes.

Reinstalled drivers etc. No help

One day everything starts working again...kinda

Go on holiday, come back and...gues what...its worse than it has ever been.

Remake fan profile on rivatuner, no help.

I am on Vista yes,
I did a couple of stress tests and it failed, until I made a profile in Rivatuner. In the past this has helped with the stress test but Is till suffered crashing in games. But now the game seems to be working too. It must have been 1 of those suttle changes that i made this time which made the difference.
 
Still not working properly, it seems to be getting worse. Before post i can hear the fan loud. Then it seems to be going minimum whatever the temperature.

The fan speed is definately wrong. Even when i used rivatuner at 100% it crashed (on desktop)

what could it be

would the 3870 fanfix bios work for this 3870 x2 powercolor
:confused::mad::(
 
Does anyone know

1. Wheather the Fan fix bios will help me
2. Where can I get it.
3. Which program to flash it with and where to get it.
4. Is it just like a normal bios, or is there more to it than that.
 
My psu is an Oryxx Tornado 750w

I also disabled Ati External Event Utility. But i dont think that helped.

The wierd thing is that the person I bought it from had reviewed this card and had had it for 3 weeks, aparently fine. He is called Minstermunch on overclockrs forums. But he said thre was nothing wrong with it. If I rma it and it isnt faulty i am in trouble, I did have another thread abought this

http://forums.overclockers.co.uk/showthread.php?t=17876533

but since when I first got it, it has got worse.


Problem is, i dont have any other pci-e systems to try it with.
 
I have lots of different types of crash/

1. Black screeen, fan goes loud (I think that was because the fan speed profile wasnt working, fixed that with rivatuner)

2. Crash, just randomly turns off (maybe power, although some times it crashes on desktop??)

3. Wierd stripy colours on screen (Probably heat related)


I know for a fact that my fan speed controller isnt working and i have fixed that, but are you sure it is my psu, because sometimes crash 2 happens on desktop, the graphics card cant be drawing much power then can it?
