Well, we haven't clearly identified a 4xxx specific problem so far. We're still investigating the overall numerical accuracy/correctness of our OpenCL apps in general though. Given AMD's driver quality that's no trivial, straight-forward task unfortunately.
Please be patient with us.

I posted earlier that my 4850 card had 512MB of memory so you said it would be lowered to 490MB
But ageless showed me how to chech for free mem in Boincmanager.
My 512MB card only has 480MB free
Is there any chance that you can lower again to 450MB?
I think you could have use of ATI/AMD Catalyst driver 11.12 or 12.1 for your 69xx card.
Hi,
not really, there are big problems coming up with the new drivers.
On my AMD-System I've upgraded to newest Catalyst driver and BM 7.0.11 with the effect, that collatz is no longer running. Seti has rarely Astropulse wu's for AMD and the memory on my AMD-card is too small for Albert ATI open-cl apps.
On my other system I run older drivers and older BM to be able to run MW, this project needs drivers < 11.10
An intresting fact is, that with the new HD7970 one can run the nVidia OpenCL-app, faster than the CAL-app on HD6970, without the need of latest BM. 6.12.34 is good for that ...
So, after upgrading to latest available versions I have a GPU running dry. It's really a mess with these versions and requirements.

Yes, it is a mess with the drivers, I agree on that.
And Collatz is thinking of do an Open-Cl app too, but it will be slower then the old app they say.
Today, AMD released a new beta driver, Catalyst 12.2. With this driver, Workunits are using 81% of the GPU (HD 6950@6970 full Shader). It could be even more, because the CPU limits the GPU-load. My Core i7-2600k ( 4.3GHz, only one Albert@home WU is running) is not able to deliver enough performance to bring GPU-load to 100%.
If the CPU starts crunching other WUs (one core is exclusivly for Albert@home GPU-Workunit), the GPU-load drops to 75% and lower.
Is there a chance, that CPU-load for GPU-WUs could be lowered in the future?

OK, I found a hint in the HD7900 thread.
BM 7.0.11 is latest version, but the boinc page lists only up to version 7.0.8
Has anyone a link to the newest version?
