seems like one more issue is there

if i am using range like this
49dccfd96dc5df56487436f5a1b18c4f5d34f65ddb48cb5eba34000000000000
its running fine in range but when i use 120 range it is calculating range fine but running very below and showing false collision 

this started like this
GPU#0 Cnt:0000000000000000000000000000000000000000000000000000000000000001
.....

but i set range 0x800000000000000000000000000000 to 0xffffffffffffffffffffffffffffff

is something wrong with software ?
