id ?
There is no platform_index parameter in SRBMiner. So i don't know what are you doing and on which miner

"cryptonight_type" : "normalv7",
"platform_index" : 1,
"intensity" : 0,
"double_threads" : true,
"target_temperature" : 75,
this config WORK
"cryptonight_type" : "normalv7",
"intensity" : 0,
"double_threads" : true,
"target_temperature" : 75,
This not WORK !
Try it yourself
I don't have to, im developing the damn thing

Are you using the latest v1.5.0 ? Did you download it from the link on first page or some other site ?
Also make sure you uncomment the gpu_conf settings so :
Like this:
"gpu_conf" :
[
{ "id" : 0, "intensity" : 0, "worksize" : 8, "threads" : 2, "target_temperature" : 55}
]
Not this:
/*"gpu_conf" :
[
{ "id" : 0, "intensity" : 0, "worksize" : 8, "threads" : 2, "target_temperature" : 55}
]
*/
