Numbers of hardware nvenc encoders on NVIDIA GRID K1

NVIDIA GRID K1 has 4 x entry Kepler GPUs, but in this topic nvidia - nvEncodeApp successfully make but in running it : NVENC error at CNVEncoder.cpp:1282 code=15 ( invalid struct version was used ) "nvStatus" - Stack Overflow 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 #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.
