NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. V
IL
is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low value.
3. V
IH
is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high value.
4. V
IH
and V
OH
may experience excursions above V
DDQ
. However, input signal drivers must comply with the signal quality
specifications.
5. R
VTT_TERM
is the termination on the DIMM and in not controlled by the processor.
