> 4 DIMM's supply 2.6GB/sec peak bandwidth.

Not in any real sense. Reasoning about memory systems is much less useful
than measuring them.

> If you want more bandwidth, buy a DS20E.

Why? The stream benchmark is only slightly different.

If your codes run better on the DS20E, it's probably due to DDR cache or
bigger cache.
