Cramming 6GB of memory into a shiny new Core i7 rig is great, but Samsung must think that's a little passé: the company says it's begun shipping DDR3 modules with a whopping 16GB capacity.

Samsung claims these are the "world's first and smallest high-density memory modules" to use 2Gb, 50nm DRAM chips, which are packed in dual-die configurations to allow for 16GB registered DIMMs. The modules themselves are rated for operation at 1066Mbps (or 1066MHz), and Samsung says it's the first to offer 16GB modules that can operate at 1.35V. It's not entirely clear whether the modules can actually hit their top speed at 1.35V, though.

imagine a 2U server with 2 sockets, 2xXeon Nehalem CPUs, 16 threads and 192Gb RAM; VMWare powerhouse

Using it for Tetris would indeed be quite a waste of money
