OpenCL doesn't use all 512MB

[pallas]

Hello,

First post here! I've got a question of which I couldn't find the answer anywere.
I'm on ubuntu with beta catalyst drivers on a 7790.
Even though I:

export GPU_MAX_ALLOC_PERCENT=100

I can't get past:

--thread-concurrency 7488

(because of buffer available size) while everybody can easily reach 8000 and even 8192.

Any clue?

Thanks!

I was able to solve the problem by updating the kernel (not only the driver/module).
Of course I had to reinstall fglrx after installing the new kernel.
I believe linux version 3.7 is highly suggested over the previous ones.
