oohhh, I think at the most, I had 3x GK110 Titans running on it.
I had some issues, but I always kept my memory clocks conservative, & made sure to have ALL the power plugs hooked up (the extra CPU pins, and the extra molex PCIE power)
I pushed it, but not incredibly hard. Which may be where these issues crept in? IDK, I got one of the first boards shipped, in the US.
the insanity is well documented in this thread. Luna n I almost got burned while trying to get our pre-orders shipped.
I do however remember these constant complaints
the board also had the shortest lifespan of any product I've ever owned. Like a said, It's full of the best X79 has to give, i guess I just got a good sample. I'd be willing to be they did a tiny run. It was created afte 4930k was already old.
