i7 12700H

[pavko222]

Hello uncle. I bought a new laptop with intel i7 12700H. (Replacement for my dell with 9750H where you helped me with the undervoltage). I'm attaching pictures, but I think I did my best. Please check my settings. I'm thinking of changing the laptop, but I would like a recommendation for a suitable processor that can be used undervoltage well so that I can customize it to my liking. I am attaching a link to my current ntb https://www.amazon.in/ASUS-Battery-i7-12700H-Windows-FX507ZV-LP094W/dp/B0C4TW7328 .I was also thinking about the AMD Ryzen processor - do they also experience throttling or other throttling? be removed by some program?

The 12th and 13th Gen mobile H series processors no longer support undervolting. You need a more expensive HX series processor if that feature is important to you. Even if a manufacturer includes an HX processor, they still might decide to lock out voltage control.

I have not followed the Ryzen mobile processors so I am not sure what if any throttling problems they might have.

Your settings look OK. Cooling looks poor. Probably inadequate design.

Thank you for answer. I'm thinking of sending the 12700h into the world and looking for another laptop. I am looking for a processor that will not have a gray BD Prochot and will not suffer from strangulation (or it can be removed). Does the entire 12 gen suffer from the same limitations as my 12700H? I have my eye on the 11800H processor. Is it a good choice? I want to buy a laptop mainly for games, so I will also look for a suitable graphics card (comparable to the RTX 4060). I welcome suggestions for ntb that you are satisfied with

a processor that will not have a gray BD Prochot

All of the 12th Gen and newer computers that I have seen have locked out BD PROCHOT adjustment. I believe it is possible to unlock this feature by modifying a UEFI variable.

Is it a good choice?

I have not bought a laptop for myself in almost 10 years. I prefer desktop computers that include adequate cooling. I do not have any recommendations. Be sure whatever you buy can be easily returned if you are not happy. It usually takes less than a day of testing with ThrottleStop to determine if there are some serious throttling issues or if everything is locked down.

Does the entire 12 gen suffer from the same limitations as my 12700H?

All 12th Gen H series have had voltage control removed. The ThrottleStop FIVR window will show Not Available.

Look for an HX processor. Some laptops with HX processors are locked down by the manufacturer. By modifying a couple of UEFI variables, it should be possible to unlock these laptops. If an HX processor has been locked by the manufacturer, the ThrottleStop FIVR window will show Locked. A processor that is locked can be unlocked but there is no fix if ThrottleStop reports Not Available.

I'm currently testing an interesting thing. I'm trying older versions of throttlestop and find out that some functions are available in older versions, so I want to find out what effect it will have on the performance and throttling of the 12700h

 

[unclewebb]

Settings that have been disabled in newer versions of ThrottleStop were disabled because they do not actually work.

What settings are you trying to use? Set Multiplier only works if Speed Shift is disabled. Most recent laptops enable Speed Shift in the BIOS automatically.

If BD PROCHOT is locked, it does not matter what version of ThrottleStop you are using. It is still going to be locked within the CPU. Older versions of TS might let you clear the BD PROCHOT box but this is not actually doing anything.

 

[pavko222]

Unfortunately, I don't have the money for an HX processor. In version 9.3.1, speed shift started working for me - it responds to the scroll bar in windows. Furthermore, the thermal velocity boost, ring down bin and v-max stress functions became available to me - unfortunately, I don't know their function, so I can't assess the impact on performance. in one post about 12700h I saw the turbo ratio limits setting unlocked - unfortunately I can't achieve that

 

[unclewebb]

the thermal velocity boost, ring down bin and v-max stress functions became available to me

None of these work on 12th Gen H CPUs. I did not disable these in TS 9.6 just to be a jerk. These settings are all accessed through the FIVR which is Not Available on your 12700H. Checking or clearing those boxes will not accomplish anything. That is why they are now locked.

Hi uncle. I don't like starting a new topic so I'll continue here. I ended up buying a MSI GE66 Raider with 11800h and RTX 3070. I'm attaching pictures of my setup because I can't get rid of the PL1 limitation. Please advise what else to change

11800h

So actually you did a downgrade...

 

[pavko222]

So actually you did a downgrade...

yes, but I'm more satisfied than when I had 12700h. The MSI is much cooler at idle and the BG3 game performance is exactly the same in my comparison

 

[unclewebb]

I can't get rid of the PL1 limitation.

The 11800H has a 45W TDP rating. Some manufacturers use an embedded controller (EC) to enforce this 45W limit. ThrottleStop cannot be used to fix this power limit throttling problem.

Some MSI users with an unlocked BIOS have been able to change the IMON Slope variable. This tricks the CPU so it reports half as much power consumption which helps to avoid power limit throttling. I have never done this so you will have to do some Google searching to learn more.

 

[pavko222]

I found the settings in the unlocked BOIS but I don't know what value to enter

 

[unclewebb]

You could try setting IMON Slope to 50. In theory, this should tell the CPU to report half as much power consumption. If your CPU is running at 60W, it will only report 30W. This trick is used to by-pass power limit throttling.

I have heard about this trick but I have never personally tried doing this. If you feel lucky, go for it. If your computer blows up, it wasn't me that suggested doing this.

You are in luck, MSI laptop have advanced bios, press left alt, right control, shift, and f2 to access the bios. From there you can undervolt and slightly overclock upto 2-3% the cpu. You can look up on youtube to know how to undervolt, its easy.

I set the IMON Slope to 50 - now the throttlestop shows me about 38 watts under load, so I got rid of the PL1 limitation. But I can't get rid of the PROCHOT 95 restriction and the THERMAL lights up

 

[unclewebb]

and the THERMAL lights up

Many laptops have inadequate cooling to run an 11800H at full speed and full power. Unless you can find some way to improve cooling, there is no way to improve performance. Consider replacing the thermal paste with some genuine Honeywell PTM 7950. That might help the cause.

With IMON Slope set to 50, a power consumption reading of 38W is probably somewhere around 76W actual.
