I7-10750h stable in Windows unstable on boot

[RoyalBlue]

Hello everyone, sorry if this is dumb as I'm just starting to mess with undervolting.

When I set my CPU core to -210 and cache to -80, my system is stable and my temps are looking good. I was thinking hey this ain't so bad up until I when for a reboot on my system, in which my laptop was unable to boot and I end up staring at a Dell error screen until it bluescreens.

I am able to get into it eventually after a few reboots, and when I switch profiles in throttlestop to remove the undervolt, it boots like normal.

Am I doing something wrong? I'm confused why the boot is failing when when i'm stable doing stress tests.

Laptop is a Dell g3 3500 (hot as hell without the undervolt lol).
Any help would be appreciated!

Everyone is probably sleeping but I figured I should add the FIVR screenshots

my system is stable

If you cannot reboot then your system is not stable. Being stable at full load is only part of being stable. A CPU needs to be stable when it is lightly loaded too.

Why did you crop your ThrottleStop screenshot? The part at the top that includes the CPU model is useful information when asking a question. I will assume that you have a 10750H. Many of these are not 100% stable when the cache undervolt is at -80 mV. Run the built in TS Bench test and set it to 960M. Can it complete this test without any errors being reported? I would reduce the cache voltage to -70 mV. Some people's goal is to set the voltage right on the very edge of stability. There is no need to do this. Give your CPU some more voltage so it is always stable in any situation.

Lower your core offset undervolt to -150 mV.

The problem with some computers is that during sleep or when rebooting, the BIOS does not reset the CPU voltage register like it is supposed to do. In the ThrottleStop FIVR window there is a setting that tries to deal with this problem. On the right side where it says Sleep Defaults, check both the Cache Ratio and Voltage options. The purpose of this feature is it resets your undervolt to default settings when your computer goes to sleep. This might help with the problem you are having. When your computer starts back up, if ThrottleStop is running in the background, it will automatically restore your CPU undervolt voltages. The real problem is that your undervolt is a little too aggressive but the Sleep Default settings can help cover up this problem.

I'm not sure how I managed to crop it sorry about that lol. It is indeed an i7-10750h though. Also thanks for the reply!!

I did this and ended up with 99 as the number up top (sorry I'm not sure what this number is). I ran cinebench and XTU' stress test as well with no issues.

The weird thing is I ended up pushing for -110 on the cache and everything is working fine. The retarting may have been an issue with a bios update that was apparently trying to install. Could be a coincidence it's hard to tell.

Should I still be less aggressive on my undervolt?

Thanks again for the help!

Run whatever undervolt you can run reliably. Many 10th Gen mobile CPUs tap out at -70 mV. If you can run -100 mV or -110 mV without any issues, that is great. If you ever see a BSOD, that usually means your undervolt is not stable. Make sure you can run the TS Bench test without any errors being reported. I was helping one user with a 10750H this morning and he was getting errors in this test at default voltage. That is never a good sign. A stable CPU should be able to run any test without errors being reported and without crashing.
