Features Table 7-2. Extended HALT Maximum Power Symbol PEXTENDED_HALT Quad-Core Intel® Xeon® Processor E5300 Series PEXTENDED_HALT QuadCore Intel® Xeon® Processor X5300 Series Parameter Extended HALT State Power Extended HALT State Power Min Typ Max 30/34 Unit W Notes 1,2,3 50 W 1,2 Notes: 1. The specification is at TCASE = 50°C and nominal VCC. The VID setting represents the maximum expected VID while running in HALT state. 2. This specification is characterized by design. 3. Processors running in the lowest bus ratio will enter the HALT state when the processor has executed the HALT and MWAIT instruction since the processor is already in the lowest core frequency and voltage operating point. Values represent SKUs with Extended HALT state (30 W) and without Extended HALT state (34 W). The processor exits the Extended HALT state when a break event occurs. When the processor exits the Extended HALT state, it will first transition the VID to the original value and then change the bus to core frequency ratio back to the original value. Figure 7-1.
