3870 x2 Powercolor, after........Using Rivatuner to alter fan speed

10 mins ago my computer shut down randomly

10 mins ago my computer shut down randomly,
its probably heat related. But the fan is still not as loud as when i first turn on before post, meaning that it was not running 100%, what controls gpu fan speed.
 
Some questions for you then

1. Can you set rivertuner to set fan speeds depending on the temp, if so, what settings
2. Does Rivertuner need to be open.
3. How do i use and install rivertuner. In the past i have had a driver issue or something.
 
How can I use Rivatuner to make a fan speed profile

How can I use Rivatuner to make a fan speed profile.

I went to low level system tweaks / fan

But cant see an option to change the automatic fan speed control rule???
 
Now its crashing after only 5 mins use,

I restart and it crashed while still on on desktop. This is crazy?

Im thinking of getting a refund.

It did this when i had fan set at 55% constant

Could it be a power issue,
I am using 2 x 6 pin connectors, with 750 watt psu, a Q6600 Go @ 3ghz, 4 gb ram, 1 hdd.

Is that enough power? Because i am getting some random crashes at perfectly reasonable temps

Engstrom, after I have had a chance to read further I would guess that your main issue is probably a power one… If memory serves me correctly the 3870X2 requires 1x 8pin & 1x 6pin connectors to power it. If you are only using 2x 6pin connectors then I’m not surprised that it crashes.

Sorry, But you are wrong. Ati say that you can use 2 x 6 pin connectors but you cannot use ati overdrive. I am using catalyst 8.4,

I have opened a disute in paypal and escalated it.

When you recieve it you will see what i mean. You can send it back to the manufacturer.

EDIT:

I set up a profile in Rivatuner to control the fan, but IMO if the fan controller on the card was the issue then you wouldn’t be able to alter the speed with Rivatuner at all..

You are wrong again, the default profile is not working, you can make another in rivatuner. Just to let you know how i knew it was the fan anyway. I use watercooling on my cpu so the only noise i hear is from the gpu. It was completely silent. I had to check the fan was even spinning.

I've just returned a 3870X2 (powercolor too) for a refund, I was getting similar issues, I had your issue a few times too, the screen would just go blank and the fan would speed up, even on the desk top. If you can, get a refund and wait until the 4800s come out, you'll save yourself some money. :)

Im also getting the odd crash on the desktop too. Tell monstermunch this IS a problem!!! This is an Ebay purchase and you have to feel sorry for me who spent 210 quid on it.
 
Yes Monstermunch here who btw said im 'obviously young and too inexperienced with this leel of hardware' was WRONG.

Ati say that 2 x 6 pin is fine even on the older version.

Not really too the point but, the picture on ebay showed the newer 6 pin version anyway until he emailed me to say the picture was wrong AFTER I BOUGHT IT? GRRR
