Good day!

The laptop is reaching 95-98C while gaming. NitroSense configures CPU and GPU fans at maximum speed (6K RPM). The laptop is sitting in a cooler pad. I installed the Intel XTU but the CPU Undervoltage is greyed out / unavailable. This maybe because of the firmware update?

Ver. 1.31
1.Update Insyde solution CVE-2020-5956/CVE-2020-5955/CVE-2020-5952/CVE-2020-5951

Unfortunately, my laptop got the v1.33. Can ThrottleStop do undervoltage tweakings given that it was greyed out in Intel XTU?

Hey there,

Yes, it's possibly because of the firmware/bios update. Check on Acers site for a bios rollback feature, that may work to put it back an earlier version.

Chances are if it's bios locked, then you may have the same issues with TS as you do with Intel XTU. Try and see if it works. You can tell straight away with HWMon/Info if the undervolt takes.

I'm not sure about your particular system, but on my Nitro, the update ~1.5 years ago broke intel XTU, and disable undervolt. I'm happy to say that throttlestop works perfectly. Also, if you have an I5 8300 or 9300, you can do a massive undervolt and and still be stable (My 8300H is at -321mV on CPU Core and -131 on CPU cache). Just remember to not save settings in throttlestop until you've applied and tested them. Then you can try and save voltages, and if you are stable after prolonged use, you can set throttlestop to start with windows.

Also, if your laptop is past warranty, and you're comfortable opening your computer, doing a repaste with a good quality thermal paste can drop your temps quite a bit too.

ThrottleStop works on my Nitro 5 (2019)! Horray! Testing my device via AIDA64, without undervolting both CPU and Cache for approx. -150.4 mV, it throttles down. But with applied undervolting config, it only maxed out for around 70-80C.

I just got my hands on nitro 5, both xtu and throttlestop functions are greyed out
Somehow while gaming,it maxes at 82C without throttles, with gpu oc +150 core/500 mem

I really dont want to mess with bios..

Good results! :) Keep in mind that after -230mv on core, any further just does not yield any results. This is suggested by unclewebb (TS Author). So bring it back to -230 and be happy out.

On my i7 9750h i got -221mv on core, and set it -121 on cache, and it's not had a single crash in 9 months.
