System Information
Windows 7 x64
2x GTX 780 TI 3GB

Blender Version
2.74
Short description of error
Cycles says its using 1287 MB of vram but GPU shows 1225 MB being used which means Cycles should be able to put more on the GPU. I know for a fact this happens a lot for me and my friend (Cycles not filling up the cards before quitting)

Here is an Image... for some reason it wont let me drag and drop mine here

Exact steps for others to reproduce the error

Well I dont know if you can unless you have the same GPUs

Thanks for the report, but no bug at all here, you are running out of memory. Also, please remember that memory usage reports (especially from Cycles/Blender sides) are only approximations, many different things make it rather imprecise - not to mention the fact that report is not done in real time, while crash will happen immediately when trying to allocate more memory than available…

If you look at the image I linked I used a program to show how much memory was being used on the GPU so you can see the GPU only reaches 1225 MB of vram being used so it isnt that cycles is lying to us, it actually didnt make it to the GPU before it crashed.

Here it is again.
