Hey guys!
I own a Helios 500 with 8750H cpu.
I have an unlocked BIOS so all settings all available.
I want to rely on the Predator Sense as little as possible for 2 reasons:
1) when enabling CPU power Limit MAX in the software it changes PL1 45W / PL2 56.250W to PL1 56W / PL2 70W
2) When enabling MAX Pwr limit Predator Sense automatically applies -125mV undervolt
Now I want to add more undervolt and set PL1 70W / PL2 70W.
How can I do this? I am not really familiar with Insyde BIOS. Could someone help me out who knows this type of BIOS inside-out? What do I need to set?
The menu I think is responsible for this is under advanced -> Power & Performance
Inside this I need CPU Power Management Control
After this I went inside Config TDP Configuration
Inside here I have got this:
However here I am stuck. I have set Power Limit 1 and Power Limit 2 to 70W in the blue area (which can be edited) and then rebooted, however these settings did not get enabled because after reboot the factory TDP limits (45.0/56.250 in the black area) did not change to 70/70. What did I do wrong? What do I need to set?
Thank you for your help !
ps: A fair warning to anyone with unlocked BIOS. I have removed the factory installed cheap 2666 Mhz CL 19 RAM modules and installed better quality 2666 Mhz modules with cash latency 15. I have set these modules in the BIOS to run at 2800 Mhz however I have tried to run them at 3000 Mhz (You know, for science
), but the laptop refused to boot. I have tried to sort the 2 pins responsible for CMOS reset, however the EC got so damaged from the above used RAM setting that even after CMOS reset the BIOS was not able to rewrite the default EC. Only solution was to reflash the entire BIOS with an SPI programmer. So be careful when you edit memory settings, it may brick your laptop which can only be fixed with an SPI programmer !
