Exotic stem cracking?

I bought an Exotic carbon bars and stem.
Carbon paste applied.
Bars say 8nm max so I'm doing 5nm and the stem is starting to split on one of the bolt holes?
Cross pattern tightening method used, not even reached 5nm at that point, doing 1/8th turns.

Guessing it's buggered?

Thought they were a solid brand for carbon fiber bits. :?:
Blindly playing with torque wrenches is pointless.

That's true, how ever they don't list the max torque setting on their site for the stem or on the stem itself, so went with a 5nm and didn't get there. They will list settings for other items, seat clamp is 6.5nm for example.
Yes i'm using a combination of alloy Easton stem and carbon bars for my weight i'd not bother with a carbon stem.
Think its failed that stem, i'd see what warranty they have and ask for a replacement.
It's 8 months old at this point so I believe warranty should sort it.
It hasn't cracked right though, it's only cracked where shown in the photo but I wouldn't use it like that.
