Hello everyone,I have a question

[Mr.M]

if I lower the voltage in the BIOS, and then use the Throttlestop to lower the voltage again, will the two lower settings be superimposed, or just use the settings in the bios and ignore the Throttlestop?

Software overrides BIOS because its the last one applied.

@Mr.M

Are you using a desktop computer or a laptop? What CPU do you have?

To try to answer your question, do some testing. Adjust the voltage in the BIOS, boot up and before you run ThrottleStop, delete any previous ThrottleStop.INI configuration file.

When ThrottleStop first starts, it will read whatever FIVR voltage that the BIOS has set the CPU to. Open the ThrottleStop FIVR window and see if any voltages are being reported in the FIVR monitoring table at the top right of the FIVR window.

My Asus desktop board seems to use two separate voltage control systems. When SVID Support is enabled in the BIOS, you can make adjustments with ThrottleStop to control the voltage. If SVID Support is not enabled, I think the BIOS offset voltage settings are completely separate from the FIVR voltage that ThrottleStop lets you set.

Use whatever settings work best. If you can control the voltage exactly how you want it by making adjustments in the BIOS then stick with doing that. Most people with the ability to control the voltage in the BIOS prefer doing that compared to using ThrottleStop to control the voltage. I prefer using ThrottleStop to control voltage on my desktop board but I am a little biased.

thank you,webb,im using a msi laptop,it has many options on its advanced menu,so i want to explore these settings about cpu undervolting,i will try diferent ways to find an appropriate way,and i search some file ,svid s function is Identifiy voltage ,right?

If you can rewrite those thoughts in English, that would be great.

For a laptop, I think it is best to use ThrottleStop to undervolt. If you set the wrong voltage settings in the BIOS, it is possible that your laptop will not boot up. You could be stuck at a black screen and your laptop might not post. You might have to disassemble your laptop to reset everything or you might have to send your laptop out for service. I think using ThrottleStop is a lot less dangerous compared to that.

If you set some voltage values in ThrottleStop that are not stable and your computer crashes, reboot and delete the ThrottleStop.INI configuration file and you can start again.

An even better idea is to use the first option in the Save Voltage Changes section, OK - Do not save voltages.

When you are experimenting with different voltages, none of your voltage settings will be saved for future use. This gives you time to run a benchmark or two so you can determine if your new voltage settings are stable or not. This is much safer compared to making voltage changes in the BIOS.

Not sure why more people do not use this awesome feature. Many YouTube videos recommend to disable this safety feature immediately. Bad advice is everywhere, except here of course.

sorry about my vocabulary

No worries. Your English is a lot better than my Mandarin.
I sometimes forget that people from all over the world use this forum.

Did you find some good voltage settings yet?

i just use our throttlestop,cause i feel easy to set .i set the core voltage offset -0.65,and cache -0.25, and use the turbo limits ,set epp 32, my machine now have a low noise and a good performance ,throttle is really useful,
