Sure it's for workstations and servers, but look at that thing!!!!!!
Computex 07: For servers and workstations
ATP had an 8GB double height DDR2 667 ECC registered memory module on display at its stand at Computex.
Now this might not be too interesting to the average gamer, but for anyone that's running high end servers, this is very interesting as long as the price is right.
You could easily double the memory capacity of 2U and bigger servers with these modules and even a server with only four memory slots could house 32GB.
