I've got a similar system, but with 3 GB. But I haven't been listed in the 
browser yet so I haven't been able to give it any real workout.

Good find. The hard part here is figuring out how to identify the thread 
and what it's doing. Maybe knowing this, DICE can bring the debugger to

address of each thread or some other piece of info to identify which thread 
is which to the coders.
