Texture memory error.

I used some testing using texture memory.
But randomly texture memory gives me wrong answer and it differents.
Is there some noise in the texture memory?

41 global void non_coalesced_read_kernel(uint32_t* in, uint32_t* out, uint32_t d_data_size) {
42 uint32_t idx = threadIdx.x + blockDim.x * blockIdx.x;
43 uint32_t stride = d_data_size / blockDim.x;
44
45 for(uint32_t i = 0; i < stride; i ++) {
46 out[idx * stride + i] = in[idx * stride + i];
47 }
48 }

50 global void texture_non_coalesced_read_kernel(uint32_t* in, uint32_t* out, uint32_t d_data_size) {
51 uint32_t idx = threadIdx.x + blockDim.x * blockIdx.x;
52 uint32_t stride = d_data_size / blockDim.x;
53
54 for(uint32_t i = 0; i < stride; i ++) {
55 out[idx * stride + i] = tex1Dfetch(texRef, idx * stride + i);
56 }
57 }

That non_coalesed_read_kernel gives me write answer but texture_non_coalesced_read_kernel is not.
It gives me wrong data. But it is not fixed, it is random.

Could you help me?

Your kernel code looks fine. The problem is probably in the code that you use to setup the texture. Are you sure that you are copying the data to the texture correctly?
