Notes:
1.Physical Rank is used to calculate DIMM capacity.
2.Command Address Timing is 1N.
3.Only 2Gb/4Gb DRAMs are supported and validated.
4.The speeds listed are estimated only and will be verified through simulation.
5.Please refer to the
6.For
7.DDP is for Dual Die Package DRAM stacking.
8."P" Means "Planer Monolithic DRAM Die."
Notes and Restrictions
•For the memory modules to work properly, please install DIMM modules in pairs (with an even number of DIMMs installed).
•All channels in a system will run at the fastest common frequency.
