Electrical Specifications
8.
I
CC_MAX
specification is based on the V
CC_MAX
loadline. Refer to Figure 1 for details.
9. These Processors have CPUID = 06FBh
10.The maximum instantaneous current the processor will draw while the thermal control circuit is active (as
indicated by the assertion of PROCHOT#) is the same as the maximum I
CC
for the processor.
11.V
TT
must be provided via a separate voltage source and not be connected to V
CC
. This specification is measured
at the land.
12.Baseboard bandwidth is limited to 20 MHz.
13.This is maximum total current drawn from V
TT
plane by only the processor. This specification does not include
the current coming from R
TT
(through the signal line). Refer to the Voltage Regulator-Down (VRD) 11.0 Processor
Power Delivery Design Guidelines For Desktop LGA775 Socket to determine the total I
TT
drawn by the system.
This parameter is based on design characterization and is not tested.

NOTES:
1. The loadline specification includes both static and transient limits except for overshoot allowed
as shown in
Section 2.5.3.
2. This table is intended to aid in reading discrete points on Figure 1.
3. The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE
lands. Voltage regulation feedback for voltage regulator circuits must be taken from processor
VCC and VSS lands. Refer to the
Voltage Regulator-Down (VRD) 11.0 Processor Power Delivery Design
Guidelines For Desktop LGA775 Socket
for socket loadline guidelines and VR implementation details.
4. Adherence to this loadline specification is required to ensure reliable processor operation.
