Vray RT CUDA crash on ASUS 970 Strix 4GB

Hello,
This is my second problem with RT. Here is my configuration:
-Windows 8.1 Pro 64bit
-3ds max 2015 64bit with updates
-Vray 2.50.01
-Asus Strix 970 4GB with nvidia drivers 344.16 WHQL
When I set Windows RT as main renderer, select CUDA single kernel and press Render after second I receive error message. Please find attached screenshot.
Should I install or setup anything else except standard nvidia drivers and choosing RT renderer with CUDA?

The current V-Ray 2.50 does not include the GPU code for the Maxwell architecture, so it won’t work. We will need to get you a new build of V-Ray.

Best regards,
Vlado

It would be great :]
