after quite a bit of testing of the new SP3 update I found that the new adaptive sampling algorithm is problematic with some scenes, no matter how much I lower the noise threshold I still get a certain amount of undesired grain in my renders.
so far disabling the new adaptive sampling algorithm via maxscript has been the only solution.
(renderers.current.twoLevel_adaptiveMethod=0)
My particular scene has a large amount of IES lights I've always had to use significantly more subdivs on those lights to get clean renders, I don't know if this contributes to the problem.
I'm using subpixel-mapping OFF and recommended setting per the "Cheatsheet: How to get a Cleaner image with SP3" thread.
