Can't get work for ATI GPU

Hi
I have some ATI cards not working on Einstein , usually I use Nvidia cards and they work without problems
For example :
GPU card : ATI 7970
System : Windows 7 64 Ultimate v. 6.1 build 7601 SP1
Boinc manager : 7.0.28 (x64)
CCC : 12.11 beta 4
GPUZ OPENCL is checked
If I detach and reconnect to Einstein in the project folder there isn’t any exe file and in the boinc log there is a message “not reporting or requesting tasksâ€
What is wrong ?
Thank you for help

You've got your preferences set to not use the ATI cards. From the scheduler log of your host 6149605:
So go to your account, on to the Einstein@Home project preferences, edit them, check "Use ATI GPU?" and save the changes. Then update BOINC through BOINC Manager->Advanced view->Projects tab->Select Einstein->Update.
Ok thank you very much for

Ok thank you very much for support – Now it work
There is a bad translation in the preference page
They translated "Use ATI GPU" in Usa la CPU (USE CPU)
I beleive not all ATI/AMD

I beleive not all ATI/AMD video cards will work well with Graphic chips. I habe an new AND 6970 card that has single and double floating computing in its bios, and it runs 5 time faster then my 6 core AMD processor. My other AMD cards 6770, 6450 and 5570 are very slow and afre slower than the CPU. I beleive it is if the chip has single aMD DOUBLE FLAOTING POINT COMPUTATION. tHESE ARE LISTED IN THE TECHINICAL SPEC ON THE amd SITE
If your 6970 runs only 5

If your 6970 runs only 5 times faster than your CPU, you have a problem with drivers. My HD6850 does a BRP4 in around 2,350 seconds. My CPU would take around 23,000 seconds.
That 10K RAC I have here is by only running BRP4 on my HD6850, I don't run any work here anymore on my CPU.
This project does not require a double precision GPU. Therefore, double precision GPUs are not necessarily faster than single precision GPUs only because they are double precision.
Now, having said that, nothing in your computer list shows that you have any of the GPUs you claim to have, or that you are using any of them on this project. So how could you know?
RE: If your 6970 runs only

You have to look at the 'all computers' link, his rac is zero so they haven't crunched in a while.
Anyway Bill B the drivers are NOT the newest, you can see both what you have and get the newest ones here:

RE: You have to look at the

I did look there, but even then he doesn't show to have a 6970, a 6770, a 6450 or a 5570. Just a generic Juniper (which is a 5700) and a 2300/2400/3200.

You are correct!
Milkey and Ageless I have 3

Milkey and Ageless I have 3 differant accounts and 4 diffearnt machines. I run Win 7 64 bit on all and look at the Thread preformace. Bonic does stress my AMD 6 core running at 3.6 GHZ, My comparison is just an estimate. When I see the six core and the 6970 start the same time, then 2 hrs later the 6 core tasks are at 10 percent and the 0.5 gpu is at 30 percent I know ir is much faster. I have images these drives to save licences and currently onlt run the 6970 on bonic. I have not run the 6770, 5570 and the 6450 in a long time. Bonic is an excelent stress test. Do you know how to tranfere completed data without accepting new task - assignments?
RE: Do you know how to

I explained how to do that in a reply to the thread you started.

RE: When I see the six core

You run 2 tasks at the same time on the GPU, plus you run those without giving them a full CPU core. The OpenCL GPU tasks at Einstein require a free CPU core to really fly.
To achieve this, set BOINC to use all but one CPU core, in your case set the preference "On multiprocessors, use at most XX% of the processors" to 83.33%. This tells BOINC to use 5 CPU cores for normal CPU calculations and leave one core free for anything else to use it. That anything else is the GPU.
When you set preferences up like that, you'll see that your GPU tasks start to fly out of there. Not one run in 6 hours, but perhaps 12 run in 6 hours. And then it really doesn't matter that you have one CPU core less doing work. Your science output will increase plenty-fold.
