Repeated Failed Rendering 4k composition in After Effects CC

I am having repeated errors while rendering a 4k composition in Adobe After Effects CC. The composition is setup with the pixel ratio is 3840x2160 at 29.97FPS. I did this to match the output of the video that I will later attach to finish the composition I had generated in After Effects. The composition is about 12s long and takes about 12min(estimated) to render on my current platform. (14gb Ram, GeForce GTX 970, 4tb extra hardrive).
