Processor Configuration Registers 

MEM_TRML_ESTIMATION_CONFIG—Memory  

This register contains configuration regarding VTS temperature estimation calculations 
that are done by PCODE.

VTS multiplier (VTS_MULTIPLIER)
The VTS multiplier serves as a multiplier for the translation of the 

memory BW to temperature. The units are given in  

1 / power(2,44).

Uncore

VTS time constant (VTS_TIME_CONSTANT)
This factor is relevant only for BW based temperature estimation. 

It is equal to "1 minus alpha".
The value of the time constant (1 – alpha) is determined by 

VTS_TIME_CONSTANT / power(2,25) per 1 mSec.

VTS offset adder (VTS_OFFSET) 
The offset is intended to provide a temperature proxy offset, so 

the option of having a fixed adder to VTS output is available.

Disable EXTTS# (DISABLE_EXTTS)
When set, the processor will ignore the EXTTS# signal status that 

it receives from the PCH through PM_SYNC messaging.

Disable virtual Temperature Sensor (DISABLE_VTS)
When set, the processor will ignore the VTS.

(DISABLE_PECI_INJECT_TEMP)
When set, the processor will ignore any DRAM temperature 

written to it over the PECI bus.
0 = Enable
