Cannot undervolt MSI GP76 Leopard with 11th Gen i7-11800H and RTX 3080 and still sometimes freezes/crashes in game

[OT1982]

Hello everybody

I am a total newbie of undervolting/overclocking & co, please be patient

A couple of months ago I bought an MSI GP76 Leopard bundled with an Intel 11th Gen i7-11800H CPU and an Nvidia RTX 3080 GPU.
The laptop itself is very performant (even though the fans kick in quite loudly even on < 70°C temps).

I wanted to undervolt it (did it only once on an MSI GE75 Raider with a -350mV offset on both CPU core and cache), but even with lower offsets (-70.3mV CPU core and cache, -30mV Intel GPU), the laptop freezes on Throttlestop Benchmark freezes after 4 seconds. I thought "Ok, maybe it is already receiving low voltage by default, let's not undervolt it".
But then playing AC Valhalla at max settings (temps never go over around 85°C) sometimes results in freezes or crashes to desktop. Seeing the resemblance with the freeze on TS Benchmark, I thought "Maybe it is by default receiving not enough voltage and it would be more stable with an "overvoltage"?".

Can anyone please help me with this situation?

Thank you very much!

my Asus Fx706H whit the same CPU it's rock stable whit -70,3mV CPU -50,8mV Cache and -30mV Intel CPU
try less undervolt on cache

with a -350mV offset on both CPU core and cache

I have never once seen a -350 mV core and cache offset undervolt work at all let alone work reliably. An undervolt that big is definitely not the norm. Unless I can see a screenshot of the FIVR window with those numbers in the monitoring table, I would have to guess that the -350 mV undervolt was not being applied to both the CPU core and cache.

-30mV Intel GPU

If you have a Nvidia GPU, there is no reason to undervolt the Intel GPU. This can cause instability and will gain you virtually nothing. The Intel GPU is not a significant source of power consumption or heat when playing a game on the Nvidia GPU so do not waste your time undervolting this.

the laptop freezes on ThrottleStop Benchmark

Does this happen when all of the offset voltages are set to +0.0000? A stable computer should have no problem running any TS Bench test without locking up or reporting any errors. If you cannot do this at default voltage then you might have a problem with your memory. It is very rare for an almost new Intel retail CPU to be unstable at default voltage.

Post some screenshots if you need help.

Hello Dismission, I've tried your offsets and the TS benchmark went smoothly.
Valhalla crashed to the desktop only once after a couple of hours.
Thank you.

Hello Unclewebb, if you say so I must surely remember the wrong values. All I'm sure of is that it was more than -100mV.
I will try not to undervolt the Intel GPU and see how it runs.
Concerning the TS benchmark freezing, it was only with -70.3mV CPU core and cache, -30mV Intel GPU.
Thank you.

it was only with -70.3mV CPU core and cache

If you cannot complete a TS Bench test at -70 mV then you need to reduce the undervolt to -60 mV or more likely -50 mV for the core and the cache. All CPUs are not created equal. You have to find voltage settings that work best for your CPU.

Thank you, Unclewebb.
Do you apply the sentence "All CPUs are not created equal" to different CPU models or to different units of the same exact model?
Anyway, is there a rule or equation linking the voltage between core and cache voltage?

All CPUs are not created equal

If they manufactured CPUs one at a time then it might be possible to come up with a very consistent manufacturing process so there would be little variation from one to the next. That is not how CPU manufacturing works.

Explainer: What is Chip Binning?

You bought a new CPU and it seems to run cool, so you try a bit of overclocking. The GHz climb higher. Did you hit the silicon...

All CPUs are unique. Your 11800H might be similar to other 11800H processors but it is not the same. There is no magic rule or formula. The only way to find out what works best for your CPU is to test and adjust your CPU.

That was great reading.
