Msi Vector 16HX Undervolt

[MyKaiSama]

First of all, I apologize for my bad English, so I'll use Google Translate. I have an MSI Vector 16HX A13VHG with an i7 13700HX and an rtx 4080. I'm complaining about the high temperatures, but I don't have any knowledge of undervolting, so I can't do much. Is there any way I can stabilize my system at least a little bit?

Open the FIVR window, press the V/F Point button and set V/F Point 1 to 150 for each profile. Do the same for both the core and the cache V/F offsets in this window. It should look like this.

Press OK.

In the FIVR window set the CPU Core and CPU P Cache to a negative offset value of -125 mV. I am using offset values of -150 mV. For you, start conservatively and set both values to -125 mV. Play some games and see if your computer is stable. If everything is OK, you can try increasing the undervolt. If your computer crashes, decrease the undervolt. Undervolting the HX processors is not rocket science.

I have also undervolted the Intel GPU and iGPU Unslice by -100 mV. This makes very little difference so I would suggest leaving these two voltages at +0.0000.

If you have any problems, post screenshots of the FIVR and TPL windows so I can see your settings.

In the ThrottleStop 9.7.2 download, there is a link to the Ultimate ThrottleStop Settings Guide written by Valour549. He shows how to undervolt his 14900HX which is very similar to any other 13th or 14th Gen HX processor.

Most modern laptops with Intel HX processors are very powerful. The bad part is they tend to run very hot. Once you learn how to make some adjustments in ThrottleStop you should be able to run your laptop a little cooler without losing too much performance.

Thanks, I can't wait to try it! I'll let you know the first result right away

Is That True? Should i check the Use Core V/F Offsets and Use Cache V/F Offsets ?

Should i check the Use Core V/F Offsets and Use Cache V/F Offsets ?

Yes.

It does not work unless both of those boxes are checked. My screenshot shows that both boxes are checked. This should be done first.

Thanks, the system seems very stable at the moment. But I'm asking out of curiosity and to really learn these things. Why didn't we undervolt the E cache? Also, do I need to make any other changes or will these be enough? I don't need to change anything other than just finding the correct offset value, right? Also, I get some limit errors, but thermal errors are normal since I haven't changed my thermal paste yet and TVB isn't that important to me. I'm also afraid that removing EDP Other might damage my device because I'm not in very reliable temperatures and sometimes the system needs to limit. I guess there's no big deal about that either. But I still wanted to ask you

 

[MyKaiSama]

I found my settings to be quite stable at the -120 offset value. If I switch these settings to MSI BIOS, will it be more stable? Do I need to do anything else?

To get rid of TVB throttling, try clearing the Thermal Velocity Boost box in the ThrottleStop FIVR window.

Some EDP throttling seems inevitable. I set Power Limit 4 to the max, 1023 and I set IccMax to the max, 511.75, for the CPU Core, P Cache, Intel GPU and iGPU Unslice.

I found my settings to be quite stable at the -120 offset value.

Did you try going higher? I have never tested a 13700HX. I do not know what undervolt values are possible before you lose stability. My 14900HX is quite stable at -150 mV but starts to randomly crash in Cinebench at -160 mV.

Why didn't we undervolt the E cache?

I have never done any testing of this. Other users have told me that it does not make much difference. The CPU Core and P Cache are the two most important voltages. If you do some E cache testing, let me know your results.

Thanks, the system seems very stable at the moment.

You are welcome. An undervolt that is 100% stable is more important to me than trying to come up with the perfect settings that might crash if the sun comes out that day. Did reducing the voltage help with your high temperatures? Often times it does not make much difference. Lowering the voltage will lower power consumption, and this will allow the CPU to run faster. Do not be surprised if the temperatures are exactly the same whether you undervolt or not. Anything under 100°C is the new normal for gaming laptops.

I used Google translate to fix your last post. English only on this forum.

@MyKaiSama

Yes, the value you suggested was exactly right. However, I set it to -120 offset just to be sure. Now I can play my favorite game Assassins Creed Shadow smoothly and coolly. My temperatures that jumped to 98 dropped from 87 to below 80, there is about a 5-6% performance hit with GPU undervolt, but it is perfect for me. However, I think I am currently experiencing a scary blue screen in Assassins Creed Shadows due to an issue with nvidia drivers. I can play smoothly without even experiencing micro stutters. If Undervolt is just that, I am really relieved, the youtube guides were really scary. If you can suggest any improvements I can make, I would be very happy. Thanks for your help

[MyKaiSama]

Sorry for using wrong languange

 

[unclewebb]

If you can suggest any improvements

If everything is running great then you probably do not need any improvements.

I like setting all of the current limits to the max. I am not sure if this is a safe thing to do so you might not want to do this.

I set IccMax to the max, 511.75, for the CPU Core, P Cache, Intel GPU and iGPU Unslice. I also set Power Limit 4 to the max, 1023. This can help with some EDP throttling problems and it might also help with some random crashes where your laptop will just turn itself off. Clearing the V-Max Stress box might help too.

The older 0x116 microcode that you and I are both using does not seem to use high voltage like the newer 0x12B microcode can use.

If you ever want to test using the newer microcode versions, follow this guide. This lets you update the CPU microcode version without having to install an updated BIOS version.

Let me start with a small background info... Since we know all Intel's fiasco about what is happening with Raptor Lake/Raptor Lake Refresh which is Intel's codename for the 13th and 14th generations of Intel Core processors, Most OEM/Vendors doesn't want to provide BIOS update that includes...

I can play smoothly

That is good news. You have a little more temperature headroom so less worries. Undervolting a 14900HX is really not that difficult. You can get some really good results with only a few minor changes. Not sure why some guides are so complicated.

I'm sorry for the late reply, but I had to test the stability of the system for a while. I found -150 Core, -150 P Cache and -100 E Cache very stable. However, I have a few questions. I used the micro code you suggested for a while about 3-4 days and I realised that it was not stable. I'm worried about whether it damaged my CPU. Did it damage my CPU, or how can I test it? Another question I have is about the TPL tab. I won't be able to send a picture because I can't reach my information right now, but I'll try to explain it as best I can. I removed the Disable Controls option without touching the default settings on the TPL tab. Then I removed the clamp 1 tick and checked the sync MMIO and MMIO lock click. My real question is. MMIO I'm not sure exactly what it is, I searched on reddit but I wasn't exactly sure. What is MMIO? And as a result of these operations, will my watt values increase and my performance increase, or will my watt value decrease and my computer work more cooler?

@unclewebb

And it may sound a little abdurd, but although the current undervolt is stable, it is quite extreme. The absurd thing is that when I lower these values to some what, the stability deteriorates. Blue screen etc. Although I don't get mistakes, micro stutters are increasing in games. Isn't there an easy way to find a lower and more stable value
