I have xfx r7-260x-cnb4 2gb videocard. And I can't get any tasks, because your server thinks that it's r38xx.

Try downgrading your driver to version 13.10, the newest versions are not always helpful to crunching. If you are also a gamer though that is probably NOT a good idea. The new AMD R series cards are different then previous models, but you seem to have already installed the APP software needed to make them work at most projects. I don't see any other obstacles from what you posted.

I just saw this at PrimeGrid which relates to your problem too:
"CGN 1.1 vs CGN 1.0 cards. R7-260X = 7790, both Bonaire based, both are CGN 1.1, both have CAL deprecated in any catalyst driver later than 13.4.

R9-280X = 7970, both are Tahiti based, both are CGN 1.0, both have CAL enabled in later drivers.

Currently running 2 r9-280X's, and using 14.4 drivers. Used to run a 7790, and had to use 13.4, in order to not fiddle with app_info.xml.
Not a Primegrid problem, nor a Boinc problem. AMD has decided to deprecate CAL, and has done so for their CGN 1.1 cards, and probably also will do so for the CGN 1.0 cards later."

Ok, the same problem with new igp like Kalindi (Kabini/Athlon APU) and Spectre (Kaveri APU).

So I'll try it with the app_info.xml.

Hi all.
Trying to get the 5 month old HpPavillon of my son ("[PUGLIA] Francesco")before the imminent Margherita Hack challenge on BoincStats, I started some workunit yesterday, for both CPU and GPU.
But no GPU wu's came, until the last message in that quote:

At the beginning of the log BOINC recognizes the GPU and declare the OpenCL availability, but Milky says "nope" :(
I'm doing something wrong?
