So, maybe there was reason related to the memory for those lockups at E3.

Lockups at E3?

Don't tell me they made a machine where the CPU and GPU could access the same portion of memory at the same time.....

Screen Freezes.  There were two demos, I don't recall which exactly, the Bungie one for sure, and another, where the screen froze. 

There is something about GDDR5, where the memory needs to be flushed, it isn't the same as DDR3.  I don't know the technicals though.  I read a conversation about it and it kept going back and forth over which had what benefit and which had what drawback.  Intertesting technical thread but no one was a tech expert. 

I would have thought that such a thing would be a given, since it's WHY we don't use GDDR5 in PCs for primary RAM. Surely they wouldn't have missed such an obvious oversight.

I'm starting to wonder if they tried to remove the partition between CPU and GPU memory allocation, causing hardware deadlocks, or perhaps strangulation with the slower memory interface choking out access of the faster memory interface.
