Rendering Artifacts...

[jarane]

Hi all,
I'm rendering shiny black plastic products and found some nasty artifacts, as well as banding.
It's a default material with no modifications or textures applied.

Please see pics attached.
Any help will be welcomed.

Thanks in advance,
E.C.

Tried rendering with different settings (up to Samples 128, Ray Bounces 32), with similar or worse results.
