dont disable thermal throttling

There are no settings in ThrottleStop that can be used to disable thermal throttling. If an Intel CPU gets too hot, it will thermal throttle to protect itself from any damage.

 

Setting Speed Shift EPP to 0 is equivalent to using the Windows High Performance power plan. Doing this is not going to hurt anything. 

Hello, I have question about throttlestop, If I will set up speed shift on 0 this will be safe for my gaming laptop when I play any games? And If I will make changes many times for eg. When I finished playing and I will change my settings from high performance to low, for power save mode and I will change SpeedShift at any time, will be OK for my laptop too? 

Thanks,

Safe in both cases, just dont disable thermal throttling.

Thank you for answer, I keep eye on GPU and CPU temps, I changed values on turbo boost power limits on lower ones for better control.

BD PROCHOT is thermal throttling setting, untick that and the CPU will allow itself to go beyond the default Tjmax.

 

I've used TS on my laptop almost 3 years, I played with all these settings.

That is not what BD PROCHOT does. Whether BD PROCHOT is enabled or disabled or checked or not checked, this does not have anything to do with allowing the CPU to go beyond TJ Max. The ability to go beyond the TJ Max temperature was deliberately left out of ThrottleStop to keep users CPUs at a safe temperature like Intel intended. 

 

The PROCHOT thermal throttling signal and the BD PROCHOT signal are two completely separate signals within the CPU. BD PROCHOT has nothing to do with thermal throttling of the CPU.

Then interesting, I can go beyond the 100C thermal limit with BD PROCHOT unchecked but not when it's checked.

beyond the 100C thermal limit

You cannot go beyond the 100°C thermal limit whether BD PROCHOT is checked or not. If TJ Max is set to 100°C, thermal throttling will start at this temperature.

 

You can use ThrottleStop to set a PROCHOT Offset temperature to force the CPU to thermal throttle at a lower temperature but you cannot use any feature in ThrottleStop to force the CPU to throttle at a higher temperature.

That's what I can do on my laptop. I'm talking about what I can do here, not whether it should.

Can you post a screenshot of that? Many 3rd Gen CPUs had the thermal throttling temperature set to 105°C. What CPU do you have?

 

Thermal throttling has been thoroughly tested while using ThrottleStop. When throttling starts, the CPU multiplier begins to drop. In this example, when the hottest spot on the CPU hits 100°C, the multiplier begins to drop from 52.00. ThrottleStop shows HOT which confirms that the PROCHOT thermal throttling signal is working correctly.

 

E2Fgum6.png

 

Here is some testing of a 3rd Gen CPU. At 101°C, it has still not triggered any thermal throttling. That is normal for these CPUs.

The Intel CPU and Intel GPU are both at 101°C and both are still running at full speed.

 

xwIZ5h4.png

 

With all of the Intel Core i temperature sensors, they stop reporting temperature data at whatever the thermal throttling temperature is set to. If TJ Max is set to 100°C, the core temperature sensors are blocked from reporting any temperature higher than 100°C. What monitoring software were you using for your test? 

 

Here is one last test to prove that BD PROCHOT and PROCHOT are not the same.

The CPU multiplier has dropped below 52 and the maximum temperature is at 100°C.

The CPU must be thermal throttling even with BD PROCHOT not checked.

@Jurrunio If your CPU is being allowed to go beyond 100°C without thermal throttling kicking in then the BIOS is not correctly setting up your CPU.

 

My Asus desktop board does not disable thermal throttling and ThrottleStop cannot be used to disable thermal throttling either.

 

Have a look at HWiNFO. Check to see if TM1 and TM2 have been disabled. Intel says these are always supposed to be enabled. 

 

image.png.75cb847e7af49e4fc56606661f94e214.png

 

When TM1 and TM2 are disabled, my CPU does not thermal throttle either.

 

image.png.95f22c6d145d87b2ef2c5419279f673b.png

 

Try running CPU-Z, click on the About tab and press the Save Report (.TXT) button. Have a look in this report for MSR 0x1A0.

 

MSR 0x000001A0        0x00000000    0x00850089

 

If that MSR ends in 9 then TM1 and TM2 should be enabled. If it ends in 1 then this MSR is not being setup correctly and thermal throttling will be disabled. 

 

Here is what Intel says.

 

System BIOS must set this bit to be operating within spec.

Check with HWiNFO to see if Thermal Monitor TM1 and TM2 are enabled. It is up to the BIOS to enable these. Also check the register report with CPU-Z. MSR 0x1A0 will confirm if these are enabled or not. 

 

Sometimes the BIOS is broken and these will not be enabled on each core like they are supposed to be.

Disabling TM1 and TM2 is one way to disable thermal throttling but there are a few other ways too. What does MSR 0x1FC show in CPU-Z? I know there is a bit in this register that can be set or cleared to disable thermal throttling but not sure which one at the moment. If your 0x1FC register looks much different than my register, I will try to look into this further. 

 

MSR 0x000001FC        0x00000000    0x003C005E
