HDAMB, designed around the AMD Opteron™  processor, can simplify business transitions and minimize integration complexity by offering simultaneous 32- and 64-bit high performance computing. HDAMB can easily transition to 64-bit technology at the user's desired pace without sacrificing 32-bit performance, and provide a seamless integration to 64-bit applications.

Another important feature of HDAMB is support of up to 8GB DDR 400/333 registered memory through four memory DIMM slots. The AMD Opteron™  has an integrated DDR memory controller in the processor, which can greatly increase memory bandwidth and allow RAM to be directly available to the processor at significantly reduced latencies. The performance is more spectacular in a multiprocessing environment.

HDAMB utilizes all of the wonderful features of the AMD Opteron™  processor, and helps to simplify today's IT environments allowing businesses to grow into 64-bit computing.
