Real Temp - New temp program for Intel Core processors

[Cy4n1d3]

Don't know if this has been asked before..
Does the program detect throttling due to signals sent by the cpu or simply by comparing temps to tjmax?

Good question. The PROCHOT# flags that will be displayed in RealTemp are based on reading that specific data from the CPU. For the techy types, this info comes from reading MSR 0x19C. Bits [22:16] contain the 7 bits of DTS data and bits 0 and 1 in that same MSR contain the flags for PROCHOT#.

You can read all about what they mean by downloading volume 3A of the Intel manuals and reading this chapter:

13.4.2.5 Thermal Status Information

This feature was tested and it definitely works. The interesting thing is that the History flag gets set just before the Status flag gets set as shown in this picture and throttling gets flagged just before DTS reaches zero.



That's a good thing since if there is any throttling at all, this bit will remain set until you reboot. You don't even need to have RealTemp running since this bit is set within the processor and will remain set even after the processor cools down.

When you get more carried away then they'll all light up.



But if your brother thinks he can turn off RealTemp to cover up the evidence then you can still catch him by starting up RealTemp.



The evidence is there even though RealTemp doesn't show any unusual temperatures in the Maximum columns.

Richard Dower: This round of beta testing is pretty much done so RealTemp 2.5 should be available by tomorrow.

Ah ok, I see.
Was just curious how my cpu was able to reach throttling-temp with ~1.35 volts on air cooling

From what i know it detects throttling based on the CPU signal w/c is not dependent on the TjMAX
