If that is the case and the paste has never been re-applied (refurbishers might re-apply but can't say for sure), re-applying the thermal compound (that too, a decent quality one) should significantly improve your thermals. There is no direct fine and not fine distinction. It's a range. But if it isn't reaching PROCHOT limit (thermal throttling limit, usually around 97 C), then it is far from "not fine". Undervolting is a good idea. Start with -100mv and keep going down slightly. WIth experimentation, your system will crash so make sure not much is open and that Windows background tasks aren't doing anything, or boot into safe mode. It will just lock up or a BSOD. A hard shutdown using the power button and restart should be fine.
I didn’t grasp that section. If I overvolt too much in -mV, I’ll see BSOD or the system will freeze. But how do I then start up normally with normal/previous settings? It seems the system or the undervolt software might have saved the last values, pushed them too far.
When Windows VBS is turned on, ThrottleStop can't write or read from the CPU voltage control register. Microsoft prioritizes safety over gaming performance. The ThrottleStop FIVR window lets you choose whether your undervolt settings are saved, so you can confirm stability before saving. For testing undervolting, instruct ThrottleStop not to save settings until you're sure your system is working properly.
Start by turning off that core isolation and then experiment with -mV.
@unclewebb so just apply -100mV to core and CPU cache, save and that is it? Nothing morw to set before/after it in TS? But friends if temps are completely fine and there is no risk of damaging laptop I would not mess with TP at all.
Consider enabling Speed Shift Technology if your BIOS supports it. This feature lets the CPU reach full speed rapidly, improving performance under light loads. It’s especially useful for laptops. If your BIOS lacks this option, you can activate it through the ThrottleStop TPL window—just look for the Speed Shift box and apply. You’ll see SST displayed in green on the main screen. Skip checking the EPP settings; they’re not needed. In the FIVR window, adjust the Unlock Adjustable Voltage slider to -100 mV for both CPU core and cache. Press Apply, and the values will appear in the monitoring table under Offset. As discussed, no further action is required—just try undervolting if it helps. It significantly boosted my laptop’s usability, making it quiet and comfortable for light tasks.
SpeedStep and Speed Shift Technology are distinct features. Not all laptops offer a BIOS option to turn on Speed Shift. Certain MSI models feature a more complex BIOS where the Speed Shift setting could be concealed. If you intend to apply ThrottleStop, activate it within the TPL window. Yes, proceed and consider undervolting. Select the FIVR option, but do not save the voltages. Upon clicking OK, ThrottleStop will adjust the CPU offset voltages according to your request, though these values won’t persist afterward. If issues arise, restart the system and the offset voltages will revert to zero. Reapply ThrottleStop and you’ll notice the Offset column in the FIVR table displaying a value of +0.0000 throughout. The previous settings will no longer exist. After thorough testing and assurance of stable voltage, you may enable ThrottleStop to retain your settings for future sessions.
Sure, I'll give it a shot tomorrow. I have a free day off work. Do you think the laptop will stay stable or avoid BSOD if I turn on Speedshift from TS and it's already set in the BIOS hidden options?
