recommended driver? (gtx580)

[kimgar]

cpu is ok, OpenCL (single kernel) gives me :
cl_build_program_failure (-11)
failed to compile openCL kernels

is it a driver issue? if so, is there a recommended driver?

im on max 2012; win 7 x64; nvidia gtx580 driver 280.26

Use 275 drivers, the 280 ones don't seem to work.

I have the same card with the latest driver (1 month ago) and I couldn't use Vray RT so Vlado told me to install previous drivers.
When I installed, all was working fine.
