Техническая Спецификация для Intel Xeon Wolfdale E3210 P4X-UPE3210-316-6M1333

Datasheet

281

 shows the current consumption for the MCH in the Advanced Configuration 

and Power Interface (ACPI) S0 state. Icc max values are determined on a per-interface 

basis, at the highest frequencies for each interface. Sustained current values or Max 

current values cannot occur simultaneously on all interfaces. Sustained Values are 

measured sustained RMS maximum current consumption and includes leakage 

estimates. The measurements are made with fast silicon at 96° C Tcase temperature, 

at the Max voltage listed in 

. The Max values are maximum theoretical pre-

silicon calculated values. In some cases, the Sustained measured values have exceeded 

the Max theoretical values.

NOTES:
1.

Measurements are for current coming through chipset’s supply pins.

2.

Rail includes DLLs (and FSB sense amps on VCC).

3.

Sustained Measurements are combined because one voltage regulator on the platform 
supplies both rails on the MCH.
