... Electrical Specifications Stresses greater than those listed in Table 6 may cause permanent damage to the DRAM devices on the module. This is a stress rating only, and functional operation of the mod- ule at these or any other conditions outside those indicated in each device’s data sheet is not implied. Exposure to absolute maximum rating conditions for extended periods may adversely affect reliability ...

... Micron encourages designers to simulate the signal characteristics of the system’s mem- ory bus to ensure adequate signal integrity of the entire memory system. Power Operating voltages are specified at the DRAM, not at the edge connector of the module. Designers must account for any system voltage drops at anticipated power levels to ensure the required supply voltage is maintained. ...
