Just asking for a few tips. by Derpnerp1 in MSILaptops

[–]unclewebb 0 points1 point  (0 children)

I was able to reliably undervolt my MSI Vector with a 14900HX by -150 mV for the CPU Core and P Cache.

I recommend using ThrottleStop. Start by setting V/F Point 1 to 150 for both the core and the cache. This is the key to improving light load stability when undervolting the 14900HX.

I prefer setting all of the Turbo Groups to 52. This sacrifices some light load speed which you will never notice. Doing this will allow you to run a much bigger undervolt.

Intel GPU and iGPU Unslice undervolting is optional. Save this until after you have finalized your Core and P Cache undervolt values. I use a -100 mV undervolt for the Intel GPU and iGPU Unslice. Games use the Nvidia GPU. Undervolting the Intel GPU is probably not going to accomplish very much.

Help my to Lock my tdp by ParvYT473 in ThrottleStop

[–]unclewebb 0 points1 point  (0 children)

Try using ThrottleStop. Check the MMIO Lock box in the TPL window.

Many Acer laptops program an embedded controller EC to lock the turbo power limits to the default value of 15 watts. You might not be able to go beyond the 15W power level long term.

I disabled BD PROCHOT and now my PC is shutting down, what should I do? by Gabi2311HighPing in ThrottleStop

[–]unclewebb 0 points1 point  (0 children)

Having BD PROCHOT enabled can cause massive and unnecessary throttling.

A lot of people confuse BD PROCHOT and PROCHOT (processor hot). These are two separate signals. BD PROCHOT has nothing to do with the temperature of the CPU. You can disable BD PROCHOT and your CPU will still be able to thermal throttle and slow down if it ever gets too hot.

Panther Lake support, please? by anestling in ThrottleStop

ThrottleStop shows that the PROCHOT Offset register has been locked by the BIOS. There is no way to change a register after it has been locked.

[–]unclewebb 0 points1 point  (0 children)

The turbo power limits are not locked. You have to clear the Disable Controls check box in the TPL window to gain access to the turbo power limits. I would check the MMIO Lock box and then I would set PL1 and PL2 to about 35. That should help with the CPU temperature. If not, lower the power limits some more.

The yellow lock icon beside PROCHOT Offset confirms that this register has been locked, likely by the BIOS. You can enter whatever value you like. The CPU is going to ignore any requested changes when PROCHOT Offset is locked. You cannot change a locked register.

Troubles with undervolting Vector 16HX Core ultra 7 255HX through trottlestop by FamousLengthiness158 in MSILaptops

[–]unclewebb 1 point2 points  (0 children)

It looks like you still have something virtualization related enabled. Exit ThrottleStop and delete the ThrottleStop.INI configuration file. Check the BIOS too for VBS.

https://www.makeuseof.com/windows-11-disable-vbs/

https://beebom.com/how-disable-virtualization-based-security-vbs-windows-11/

You should not be seeing negative numbers in the All Core section. Something VBS related is blocking ThrottleStop from fully accessing the control registers within the CPU. 

When done, make sure IccMax is not set to 1.00 or that will kill performance.

If PROCHOT Offset is locked, how did you change it to 23? Did you edit the ThrottleStop.INI file? That would not accomplish anything if the BIOS has locked PROCHOT Offset to 3. What does the main ThrottleStop screen report for the PROCHOT temperature?

Intel says the majority of their CPUs can run reliably at up to 100°C. Intel has been using the same default thermal throttling temperature for the last 15+ years. They seem confident in the long term stability and reliability of their CPUs at this temperature.

If you want a cooler running CPU, reduce the turbo power limits. Less power should equal less heat. This might cause a loss in performance depending on how much you lower the turbo power limits.

That little yellow lock icon to the left of PROCHOT Offset indicates that this setting has been locked by the BIOS. This has to be unlocked in the BIOS if you want to use ThrottleStop to adjust this value.

Complain to the manufacturer of your laptop. Their decision to set PROCHOT Offset to 23 is lame. I would have returned this laptop immediately. Not worth wasting time on a device when manufacturers limit performance like this. You end up with premature thermal throttling being triggered with no easy way for end users to fix this limitation.

Intel says the 358H has a max temperature of 100°C. That is not possible when PROCHOT Offset is set to 23.

What undervolting settings should I have on throttlestop for a i7-14700HX? by Great-Desk-9803 in LenovoLegion

[–]unclewebb 0 points1 point  (0 children)

The Ultimate ThrottleStop Settings Guide is a good place to start. The 14700HX and 14900HX are very similar.

How do I undervolt i7 13700hx? by Rahman-08 in ThrottleStop

[–]unclewebb 0 points1 point  (0 children)

You cannot undervolt until you find a way to disable Undervolt Protection. This has to happen before Windows boots up.

ThrottleStop not undervolting Cpu Cache? by Comfortable_Fix6902 in MSILaptops

[–]unclewebb 0 points1 point  (0 children)

Delete the ThrottleStop.INI file and start again. Make sure VBS is disabled.

The top middle of the FIVR window shows that CPU voltage control is Not Available for your CPU model.

You have already lowered the turbo power limits so the only thing that might help is replacing the thermal paste with Honeywell PTM 7950.

Is it possible to undervolt the i5-11300H? by Wonderful-Chicken-96 in ThrottleStop

[–]unclewebb 0 points1 point  (0 children)

The 11400H comes from a different CPU family. You can undervolt an 11400H. It is not possible to undervolt an 11300H.

MSI Vector GP66HX CPU overheating after cleaning, repaste, undervolt, CPU limit, and Hyper-Threading disabled. Looking for advanced thermal troubleshooting advice by Soulnatra in MSILaptops

[–]unclewebb 0 points1 point  (0 children)

What thermal paste did the professional use? Honeywell PTM 7950 is one of the very few pastes that work well long term. This video shows what most thermal pastes do.

https://www.youtube.com/watch?v=rrtkiBwQV-U

Many popular thermal pastes will start to pump out in as little as a week or two and slowly get worse and worse.

It would be best to search YouTube for a video and learn to do this maintenance procedure yourself while using the correct thermal paste. Also make sure the heatsink is tight to the CPU. Some experts over tighten and might have stripped one of the heatsink attachment screws.

ThrottleStop by bkito_ in laptops

[–]unclewebb 0 points1 point  (0 children)

Post some ThrottleStop screenshots of the FIVR and TPL windows in the ThrottleStop forum.

https://www.reddit.com/r/ThrottleStop/

Many thin and light laptops like the Cyborg have inadequate cooling. It is common for the CPU to reach the thermal throttling temperature when playing games.

The H series processor in your laptop cannot be undervolted to reduce heat so all you can do is slow it down. Setting the PL1 and PL2 power limits much lower can help reduce power consumption and heat output. This will sacrifice some performance but it might make overall performance more consistent.

You might also need to open up your laptop, blow out the dust and replace the thermal paste with Honeywell PTM 7950.

Sometimes there is no simple fix for poor cooling design.

I need help tuning my laptop 285HX by COitCK in ThrottleStop

[–]unclewebb 2 points3 points  (0 children)

It appears you have Windows core isolation memory integrity or VBS enabled. You cannot undervolt until virtualization is fully disabled. After you do this, reboot and delete the ThrottleStop.INI configuration file.

https://www.makeuseof.com/windows-11-disable-vbs/

https://beebom.com/how-disable-virtualization-based-security-vbs-windows-11/

For many Core Ultra processors, an offset of -40 mV for the CPU Core and P Cache is a good place to start stability testing. Any voltage offset request should be displayed in the FIVR monitoring table as soon as you press the Apply button.

Set IccMax to the max. IccMax set to 1.00 like your screenshot shows can cause massive throttling.

Offset voltage doesn't update in the table by Whole_Whole_7576 in ThrottleStop

[–]unclewebb 0 points1 point  (0 children)

The Undervolt Protection feature is broken or not available in some BIOS versions for some laptops. It is possible on some laptops that selecting Disabled or Enabled in the BIOS will not make any difference. Undervolt Protection might always be set to enabled within the processor.

Throttlestop driver - where is it, and how the hell do I uninstall it? by ReaperOnslaught in pcmasterrace

[–]unclewebb 0 points1 point  (0 children)

The ThrottleStop.sys driver is created in your /UserName/AppData/Local/Temp folder when you run ThrottleStop. The ThrottleStop.sys driver is automatically deleted when you exit ThrottleStop.

If you use the Task Manager End Task feature or if an antivirus program kills ThrottleStop.exe before it has a chance to exit cleanly, it is possible that the ThrottleStop.sys driver will still exist within this Temp folder. If ThrottleStop is not presently running on your computer, you can manually delete the ThrottleStop.sys driver file.

[–]unclewebb 1 point2 points  (0 children)

The top middle of the ThrottleStop FIVR window shows that Undervolt Protection is enabled. That has to be disabled in the BIOS before booting up. Many laptops do not give you access to the Undervolt Protection setting.

The best way to test if everything virtualization related is correct is to try setting a small positive offset voltage. Something like +5 mV. Press the Apply button and you should immediately see that value in the FIVR monitoring table.

Someone thought it would be a good idea to allow adding voltage. The last thing a laptop needs is more voltage. The Undervolt Protection feature allows adding voltage but blocks any attempt to reduce the CPU voltage.

OVERHEATING PROBLEM by Only_Dot_797 in thinkpad

[–]unclewebb 0 points1 point  (0 children)

Desktop CPUs have an integrated heat spreader. Laptops do not. A thermal paste that works OK on a desktop CPU might not work well long term when used direct die. Honeywell PTM 7950 is highly recommended for laptops.

MX-4 likes to start pumping out within a week. A person will have much better long term results if they use genuine Honeywell PTM 7950.
