Ram Purchase

I'm about to buy 64gigs of ram for my 4,1 pro (flashed to 5,1).

I realize that for the moment, I don't need anything faster than 1067mhz ram.

Firstly, If I buy all the same brand in 1333mhz trim, future-proofing myself for an update, will it simply 'clock down' and work with my current 2.26ghz chips?

Secondly, are these machines super-picky with "ram timings" etc, or will most off-the-shelf 1333 chips from my local canada-computers store do the trick? I've never had a problem with fast PC's and kingston/corsair/mushkin - or heck- even "a-data" brand ram.

Opinions welcome. I just look at the prices for ram on macsales.com for the latest desktop machines and shake my head.

help?

am i in the Sterling Archer Danger Zone if i go non-ecc?

Primary Use: Logic Audio, Kontakt (mega libraries in ram), with video playing.

has anyone here, specifically, suffered any ill effects running 64gb of non-ecc?

instead of messing around, ended up buying 16gb x 2 modules from OWC, 1333. might as well future-proof and allow for gobs of ram to be installed as I need it.
