Noise grid artifact

[DrFedEx]

Hello

So I'm not sure if I'm doing anything stupid but,
does anyone know why im getting these artifacts? Its a regular grid of noise. its quite faint so you have to look close.

here it is at 200%

Its the first time im using octane to render out a 4k image. before this i havent had any issues.
these are the settings im using and i am using a i7 gtx580 pc.

Thanks in advanced

the grain shows up best against the black. This might help.

iv brightened this one up a tad in photoshop

Hi DrFedEx,
could you share a simple scene that shows the effect?
It's a bit hard to say judging only from the images already posted
