HD6950 CFX , no temp reading on secondary card.

post #1 of 13
Thread Starter 
As topic describes, I get no temp , voltage, clock etc reading on my secondary hd6950.

This is regardless of ATI driver (11.4-12.2)


373


Using asus smartdoctor I get the reading when I first start it up, then the card disappears after about 30s without notice.


Crossfire works fine, but I can`t overclock or change any of the settings on the second card.


Any takers?

Sounds like a hardware problem. Have you tried moving the 2nd GPU to a different PCIe slot? Or just using GPU2 as your primary GPU? If not, do that, and if it the readings still don't work, than your gpu is acting a fool. If the readings do work, than possibly your PCIe slot is fubar.

Good luck man.

Now, here's my question. How do I stop my wife from being so annoying?

My CCC does the same thing. Although, I do not know why Smartdoctor would not show the temp. You may want to try using MSI Afterburner. This is what I am currently using for my cards.

It's because ULPS is enabled. It's using AMD's "Power Play" and basically turning off the second card. If you disable ULPS in your registry (run regedit and then search for ULPS. Find the entry EnableULPS, there should be two, then set the values to 0) it will stop doing this. You will increase the temps a bit by doing this, however.

Will give it a shot (alternating slots that is)

On the second req: How do I stop my wife from being so annoying?

If I haven`t fixed this in six years, you shouldnt take my advice.

Removing her from the equation (throwing her the fuxx out) , but in this time of facebook and cellphones... this might bite your ass:S

Yea, try disabling ULPS before fussing around with the GPUs. I can't believe I didn't think of that. redface.gif

I did as told , it was 2 (per card)

1 was labeled Enable_ULPS_NA and one Enable_ULPS.


Changed both values to 2 on both cards : 0000 , and 0001

Still ULPS comes up on smartdoctor after CCC is initialized.

Crap


Edit: It just resets it , I`ll do it in safe mode:)

You only need to change the Enable_ULPS for each card and the values need to be 0.
