System Overview

5.6VRD VID Headers

Provides for manual control of the processor core voltage regulator output level(s). Normally, the processor should be run at its default VID (voltage identification) value as set during manufacturing. However, in the event the user needs to set a different VID value from the default value, it can be accomplished through a jumper block found on the board. Note that these headers are not populated by default.

The CPU 0 VID header is located at J9K2. CPU 1 VID header is located at J4K1. Table 5 provides the VID settings available via the VID headers.
