HIS 7850 IceQ 2gb

Random black screens are occurring now. I'll try that as soon as I am home. I did hope to try that whilst I was at work (Teamviewer into my PC) but it seems my PC either turned itself off or the internet has dropped.

Or it black screened.....

It had black screened. Can't into GPU tweak to clock it slightly, the HIS iTurbo doesn't work some some reason. Blah!

You can do it in CCC by making a profile and modifying the config file. I'll see if I can find the instructions I followed for you

Mine still hasn't black screened.

I have often suggested here increasing core/memory idle clock speeds in case one is experiencing TDR issue. It seems nobody is interested in doing it.

Here is the procedure doing it if anyone is interested:

Open Catalyst Control Center (new version since October 2011. Older versions have a different procedure.).

Make sure Enable Graphics Overdrive is unchecked in Overdrive section.

Click Presets.

Click Add preset.

Give a name to the preset (such as Speedy and note it) and save.

Now go to %USERPROFILE%\AppData\Local\ATI\ACE\Profiles\ (AppData folder is hidden. Select Show all files and folders in Folder Options.).

In Profiles folder, you will see a file called Speedy.xml. This file you have just created.

Open Speedy.xml with notepad.

In this file there is a line

name="CoreClockTarget....."
<Property name="Want_0" value="xxx00" /> (xxx00 is your idle-state core clock. Make it 40000)

and another line

name="MemoryClockTarget....."
<Property name="Want_0" value="yyy00" /> (yyy00 is your idle-state memory clock. Make it 90000)

Change only the Want_0 values. These are the idle-state clocks.

Save the file with the changes you have made.

Now go back to Catalyst Control Center.

Select the Preset called Speedy and then put a checkmark in the box next to Enable Graphics OverDrive.

Click Apply at the bottom of the Catalyst Control Center window.

Now you can see the new increased idle-state core/memory clock speeds.

Now try to give your card a good TDR if you can.

If your issue is resolved, then you may back off little by little on idle core/memory clock speeds until you find your system's lowest values, just to save energy and help GreenPeace act. If it is not resolved, good luck.

I gave it a shot. Issue didn't fix. Thinking about sending it back tomorrow now tbh. :/

What did you raise the idle clocks to?

Changed to the suggest values in your post. 40000 and 90000.

Ah right. I just raised mine (7870) to 400 / 300 which seems to have worked.

Played nexiuz yesterday and had a couple of CTD's but raising vcore ever so slightly solved it.

If that has failed I reckon return it. These things should work out the box really we shouldnt have to be changing stock settings to get them to work properly.

Yeah... I've never had any issues in the past, so I thought it was strange this time round. I'll return it and hopefully get a different card. Maybe go for an MSI or Asus one.

It's a shame after everything tried it hasn't worked.

Thanks for all your help though!
