          My notebook amd card is AMD redeon r7 M265,Then I only download the diver of  AMD redeon r7 M260 for win10 64bit,(Version 1703).

Now I code some render code with Directx11 and HLSL5. One of steps is writing data to RWTexure2D (32*19 size)

with GroupID(GroupID with 32*19).Code is here:

               [numthreads(THREAD_NUM_X, THREAD_NUM_Y, 1)]

               void main(uint3 DispatchID:SV_DispatchThreadID,uint3 GThreadID: SV_GroupThreadID,uint3 TileIndex: SV_GroupID)


                         float A;

                         //MaxDepth[TileIndex.xy] = 6;

                         InterlockedExchange(MaxDepth[TileIndex.xy].x, 6, A);

                         InterlockedExchange(MinDepth[TileIndex.xy].x, 7, A);

                         //MinDepth[TileIndex.xy] = 7;


And I read UAV Data,But I got some false result.


Then I tried others GraphcisCard like intel UMA GraphcisCard  .I got correct result.
