SP605 UG667 DDR Benchtest speed

I am running the UG667 DDR2 CDMA Benchtest demo on a SP605 (Spartan 6) board. 

The demo runs as expected and reports ~381 MBytes / second throughput.

Does any know if 381MB/S is the fastest this CDMA will move data or can I make changes to the UG667 design that would increase this throughput?

How fast is the DDR?

 

Have you looked at the refresh and row and column address times?  Perhaps this is as good as it gets?

The DDR2 on the Xilinx SP605 demo board is running at 333.5MHz (so DDR speed of 667Mb/s).
