Invalid result on NVIDIA GPUs

[0proof]

I am getting lots of invalid results while mining IPBC on NVIDIA P106-100
the nvidia.txt file was auto generated and contains for each card:
"gpu_threads_conf" :
[
// gpu: P106-100 architecture: 61
// memory: 5949/6080 MiB
// smx: 10
{ "index" : 0,
"threads" : 32, "blocks" : 30,
"bfactor" : 0, "bsleep" : 0,
"affine_to_cpu" : false, "sync_mode" : 3,
},
