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. This is the pull up/down driver resistance.
6. RTERM is the termination on the DIMM and in not controlled by the processor.
7. The minimum and maximum values for these signals are programmable by BIOS to one of the

two sets.

8. SM_RCOMPx resistance must be provided on the system board with 1% resistors. SM_RCOMPx

resistors are to V

SS

.

9. SM_DRAMPWROK must have a maximum of 15 ns rise or fall time over V

DDQ

 * 0.30 ±100 mV

and the edge must be monotonic.

10.SM_VREF is defined as V

DDQ

/2

11.Maximum-minimum range is correct; however, center point is subject to change during MRC

boot training.

12.Processor may be damaged if V

IH

 exceeds the maximum voltage for extended periods.
