**System Information**
Operating system and graphics card
Windows 7, nVidia GeForce GT 650M (Dell inspiron laptop)
**Blender Version**
Broken: 2.70 RC2 (HASH: 2525f9c )
Worked: 2.70 RC1 (HASH:19f7f9a )
**Short description of error**
Each time I try to render using GPU (viewport rendering) I get the following error at the top of 3D View window:
**Cancel | CUDA error: Invalid value in cMemAlloc(&device_pointer, size)**
When trying to render image (F12) I get black image - render does not start.
When I switch to CPU - rendering works fine in both viewport render shading and render mode.
**Exact steps for others to reproduce the error**
1) Create a scene with a cube
2) Add a plane with emission material
3) Set Viewport shading to rendered - you get the CUDA error from above.
