Only GPU working

I'm trying to add a 2nd Nvidia GPU to a computer. The 2 GPUs are 210 (16 cuda cores) and a GT 650 (300+) Cuda cores. The 210 has been been running Collatz for a couple of weeks, works on DirT, and Moo.

The Problem:
At startup BOINC shows the 210 as (not used) and it only crunches on the 640. I've added <use_all_gpus>1</use_all_gpus> to the cc_config file but it doesn't change anything.

What am I overlooking or does the difference in compute capability prohibit both cards crunching?

CUDA: NVIDIA GPU 0: GeForce GT 640 (driver version 320.49, CUDA version 5.50, compute capability 3.0, 2048MB, 1982MB available, 692 GFLOPS peak)
CUDA: NVIDIA GPU 1 (not used): GeForce 210 (driver version 320.49, CUDA version 5.50, compute capability 1.2, 1024MB, 923MB available, 59 GFLOPS peak)
OpenCL: NVIDIA GPU 0: GeForce GT 640 (driver version 320.49, device version OpenCL 1.1 CUDA, 2048MB, 1982MB available, 692 GFLOPS peak)
OpenCL: NVIDIA GPU 1 (not used): GeForce 210 (driver version 320.49, device version OpenCL 1.0 CUDA, 1024MB, 923MB available, 59 GFLOPS peak)

NEVERMIND ... there was a 2nd use_all_gpus down in the Proxy info that was set to 0.

PROBLEM SOLVED --- My Bad :))

:-bd hehe
