maximizing read bandwidth of HP DDR2 memory controller

Hi, I'm trying to maximize the read bandwidth thru the High Performance (HP) DDR2 memory controller using the Stratix III devkit & the included Micron DIMM. I am getting less than I had hoped...

If you read sequentially, than you can utilyze your DDR2-Controller up to 95%. Forget about burst and so -- just read the data until you need it.

Take care of Avalon-Master-Clock and DDR2 Clock -- it should be both the same (sys_clock or something simmilar)!
