- All specifications in this table are based on estimates and simulations or empirical data. These specifications will be updated with characterized data from silicon measurements at a later date.
- The current supplied to the DIMM modules is not included in this specification.
- Includes AC and DC error, where the AC noise is bandwidth limited to under 1 MHz, measured on package pins.
- No requirement on the breakdown of AC versus DC noise.
- The voltage specification requirements are measured on package pins as near as possible to the processor with an oscilloscope set to 100 MHz bandwidth, 1.5 pF maximum probe capacitance, and 1 MΩ minimum impedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the system is not coupled into the oscilloscope probe.
- For Entry Server applications (Windows and Linux Server OS) the expected worst-case peak current draw for the VDD2 rail will be 4.5A, this is for conditions with Tj under 95°C.
