Architecture
5.1.1
DDR
The P4080 supports DDR2 and DDR3 devices; however, the P4080DS supports only DDR3 , using
industry-standard JEDEC DDR3 2-rank and 4-rank DIMM modules. However, the system is shipped and
supported by software to support UDIMM 2-rank modules for targeted vendors. The type and vendor may
change as memory availability varies. The memory interface includes all the necessary termination and
I/O power, and is routed so as to achieve maximum performance on the memory bus.
