Re: [CPU] JCE Miner Cryptonight/forks, brand new, super fast!
Still PhenomII X6 have better performance with 6T than 5T+helper, 153 vs 141.
Could you please try the following config for your X6; just for interest 
"cpu_threads_conf" :
[
{ "cpu_architecture" : "thuban", "affine_to_cpu" : 0, "use_cache" : true },
{ "cpu_architecture" : "thuban", "affine_to_cpu" : 1, "use_cache" : true },
{ "cpu_architecture" : "thuban", "affine_to_cpu" : 2, "use_cache" : true },
{ "cpu_architecture" : "thuban", "affine_to_cpu" : 3, "use_cache" : true, "dual_mine_with": 2 },
{ "cpu_architecture" : "thuban", "affine_to_cpu" : 4, "use_cache" : true },
{ "cpu_architecture" : "thuban", "affine_to_cpu" : 5, "use_cache" : true, "dual_mine_with": 4 },
]
THEORETICALLY, this must be the fastest config for Phenom II X6

What clock is your X4 running?
Phenom II X4 905e runs at 2500 MHz.
