Nvidia ION video memory problem

(moderation:
Hey at all,
I got an Asus AT3IONT-I with NVIDIA ION graphics. I would like to use this graphic card for Boinc but Boinc shows that I just have 64mb of memory for the ION. GPU-Z shows that the ION have 512mb. I use the newest Nvidia Driver with cuda 4.0 support. Whats wrong and does anybody know how to fix this problem?
Thanks
Best regards and sorry for my bad english by the way :)

Don't worry about the English it is better than my non existent German!! What you are probably seeing is the OS adding memory to the gpu to make it seem like it has more than the 64mb it really has. This is common on laptops and other non desktop machines, they have a limited amount of space and large graphics cards with tons of memory make tons of heat which is bad for the machines, so they put in a basic gpu and them supplement their memory with desktop memory which is cheap and easy to add.
Thank you for your answer.

Thank you for your answer. Thats what I know and I think you did not understand my question :) It is possible to change everything at the settings of my Boinc to use this graphic card because windows- GPU-Z- and the Nvidia- sys info shows 512mb of memory. Just Boinc is showing me 64mb?!? Why that and why can´t Boinc use the 512mb? Hopefully you will understand what I mean :)
Thank you again

It would be too much work to code for all possible combinations of chipset and processor.

Hi,
is it this one?
It is already using your GPU; tasks list shows BRP3cuda32 as application.

See if you can change the

See if you can change the amount of memory allocated to the Ion in the BIOS,
then try a different driver, _heinz reported Boinc only reporting 64MB with 270.61 drivers, while 270.51 reported 306MB:

@Michael Thats an other card

@Michael Thats an other card with 512mb of video memory. I do not have any problem with this card.Thanks.
@Claggy Thank you. I changed in the Bios the memory settings to 512mb and just Boinc is showing me 64mb again afterwords. Like I wrote Windows ,GPU-Z and the Nvidia shows 512mb. Now I will try an other driver to fix this problem. Actually Boinc shows me that:
10.05.2011 07:58:21 NVIDIA GPU 0 (not used): ION (driver version 27061, CUDA version 4000, compute capability 1.1, 64MB, 35 GFLOPS peak)
10.05.2011 07:58:21 NVIDIA GPU 1: GeForce 210 (driver version 27061, CUDA version 4000, compute capability 1.2, 444MB, 50 GFLOPS peak)
Thanks again...
... I am done ... Boinc

... I am done ...
Boinc shows actually
10.05.2011 09:57:48 NVIDIA GPU 0 (not used): ION (driver version 26089, CUDA version 3020, compute capability 1.1, 498MB, 35 GFLOPS peak)
10.05.2011 09:57:48 NVIDIA GPU 1: GeForce 210 (driver version 26089, CUDA version 3020, compute capability 1.2, 475MB, 50 GFLOPS peak)
but now I got a new problem. Boinc is not using this card and I do not know why? I checked the setting of Boinc but everything fine?! May be this card is not compatible to Einstein or is to slow?! Do somebody know everything against this?
Thank you for all help
RE: ... I am done

another design flaw - you need to insert into your cc_config.xml:
1
If 1, use all GPUs (otherwise only the most capable ones are used)
If GPUs of different types
)
If GPUs of different types are used in one machine, BOINC by default only uses the "better" one(s). To change that, you'll have to create/modify a file named cc_config.xml in your BOINC data directory. Using this link, look for (and set the value to one).

Thanks @FrankHagen
I tried to find this .xml file but I couldn´t. Do you know perhaps where I could find this file? Many questions I know :)
Thanks a lot ...
@Gundolf_Jahn and I was to fast :) Thank you
