Numbers of hardware nvenc encoders on NVIDIA GRID K1

NVIDIA GRID K1 has 4 x entry Kepler GPUs, but in this topic http://stackoverflow.com/questions/17691145/nvencodeapp-successfully-make-but-in-running-it-nvenc-error-at-cnvencoder-cpp nvEncoder application has output:

>> GetNumberEncoders() has detected 8 CUDA capable GPU device(s) <<
[ GPU #0 - < GRID K1 > has Compute SM 3.0, NVENC Available ]
[ GPU #1 - < GRID K1 > has Compute SM 3.0, NVENC Available ]
[ GPU #2 - < GRID K1 > has Compute SM 3.0, NVENC Available ]

[ GPU #6 - < GRID K1 > has Compute SM 3.0, NVENC Available ]
[ GPU #7 - < GRID K1 > has Compute SM 3.0, NVENC Available ]

How many hardware nvenc encoders items NVIDIA GRID K1 has: 8 or 4?

There would be 2 cards in that host, so a total of 8 GPU’s.
