phong issues?

Sometimes i get this weird angular shading. Increasing the subdivisions makes the triangles and quads less visible (smaller) but still not smooth. Tweaking the phong angle doesn't help either. Has anybody any idea how to solve this? Thank you!

It's not a phong issue. It's shadow terminator problem which appears on pathtracers. It's known problem by Octane team.
