Sandy-Bridge Xeons have 4 memory lanes with max 2 connectors each.(max 8 memory sticks) 256GB with 8x 32GB-memory sticks is possible but un-likely. By the way, only ECC memory is available on such large memory sticks. A dual socket is then more likely, you gain in memory bandwith..., cheaper memory at the price of a second CPU.
