That file still only has HCC. For HFCC, there would be another set of instructions just as long with references to the files that HFCC uses to crunch.

@Bearcat- No, that will not work for GPU only. That app_info is for GPU and CPU HCC tasks. Below is what you need for GPU tasks only. Make sure your profile @ WCG for this cruncher is set to receive no CPU tasks.

<app_info>
<app>
<name>hcc1</name>
<user_friendly_name>Help Conquer Cancer</user_friendly_name>
</app>
<file_info>
<name>wcg_hcc1_img_6.56_windows_intelx86__ati_hcc1</name>
<executable/>
</file_info>
<file_info>
<name>hcckernel.cl.6.56</name>
<executable/>
</file_info>
<app_version>
<app_name>hcc1</app_name>
<version_num>656</version_num>
<platform>windows_intelx86</platform>
<plan_class>ati_hcc1</plan_class>
<avg_ncpus>1.0</avg_ncpus>
<max_ncpus>1.0</max_ncpus>
<coproc>
<type>ATI</type>
<count>.25</count>
</coproc>
<file_ref>
<file_name>wcg_hcc1_img_6.56_windows_intelx86__ati_hcc1</file_name>
<main_program/>
</file_ref>
<file_ref>
<file_name>hcckernel.cl.6.56</file_name>
<open_name>hcckernel.cl</open_name>
</file_ref>
</app_version>
</app_info>

To change the amount of tasks you want to run simultaneously change the <count>.25</count> parameter. .25 is for 4 tasks. .50 is for 2. .33 is for 3.

Once you place the file in your WCG project folder do any editing without removing the file from the projects folder. You'll need to stop and restart boinc for the changes to take effect. DO NOT remove the app_info file from the project folder if you have tasks that are still in your cache. You'll lose them. if you want to return to 1 tasks just change the <count>.25</count> parameter to 1. You will not be able to run WCG CPU tasks on this cruncher with this app_info in the projects folder.

There is no way to really know if a card is going bad but from my experience you usually start to get screen artifacts or a grey screen when it's starting to go bad. You can seriously reduce your card's power consumption by down clocking the memory. I go down at least 50% on mine. If Windows is still trying to stop and reset the driver even with the reg fix then the only other suggestion I have is to disable Aero. A good dusting with some compressed air if needed might also help.

One other thing I should have mentioned if you don't already know is when starting from scratch with the app_info file let boinc download some GPU tasks before you put the app_info file into the WCG project directory.

Its WORKING!!!!!
Thanks Nano.
Currently crunching 3 with around 2:30 to complete. Will give it a day before trying 4. Also dropped from around 350 watts to around 265 watts. Should have a new rig in by next month to make it a dedicated GPU dual card cruncher and leave my 24 thread crunchers to do grunt work on CPU wu's. Since the board has 2 x16 but one is at x8, anyone know if I will hit some kind of bottleneck on the x8 PCI-E slot?

You had to show me that. Now am wondering if I shouldn't have broken a few piggy banks to stretch for the 7970. The 8000 series should be popping out around December so won't invest in any more until then. Scored a good deal on a motherboard, processor (IB) and ram so this will be my dual GPU cruncher once its all together. Hope to be up and running by end of next month. Will post my numbers in a few days. Thanks again for all the help. Glad its up and crunching for XS week coming up. Should be one hell of a showing with GPU crunching in progress.
