M18R2 question

[Sydneyblue]

Hey all I just picked up m18 R2 with 4070 and 14900hx. 

This thing runs hot. I want to try and undervolt more then what AWCC lets me but the bios overclocking is greyed out. Does this bios allow undervolting ?

I use Throttle Stop. I have an R1 and the bios overclocking/undervolting has been hit and miss. I have ThrottleStop run at boot that adjusts my voltage down and I have my temps set to 80c -15 in bios. still creeps up to the 90s though.   It is what it is. I used the honeywell phase pads and love it so far. its all I use anymore. Only other thing is to crank your fans to max when gamin with a custom fan curve in the AWCC. However I stopped using the AWCC as it causes issues with changing power settings. It might be fixed now or better on the R2 but I dont use it. I'm always plugged in.

From what i understand the M8r2 has undervolt protection so when i use throttle stottle it only allows me to use performance wndows profile and turns off C1state. I been using AWCC oc2 with the -25 voltage offset and that seems to allow temps to drop to around what you are seeing because throttle stop cant adjust voltaage with voltage protect in place by dell. Thats what i understand but i hope im wrong

It was working for me on the R1. I have overclocking enabled in bios but I left everything on default. In performance mode set in bios. All I changed in bios was the thermal limit. Set to 15.

 

Awcc would mess with any settings I set and would get stuck in balance mode often. I couldn’t use awcc and throttle stop. Awcc would break the bios settings pretty much. I would have to revert to default and then reset the bios. 

 

I am on the latest bios for my r1. I did get an early build of the r1, so maybe there is something else going on on the hardware side I don’t know.  I also confirm my under volt with r23 scores.

So i take it your not using AWCC ? What are your thermal settings in the bios ? 

That makes perfect sense because if i disab le c1state it is never shut off when i load widnows and awcc

No, I set my keyboard color scheme and deleted AWCC.  Haven’t had it for well over a year.

Besides TCC and power setting in bios everything is default. The only downside to not having AWCC is not having fan control. It doesn’t ramp up how I’d prefer but it works.

every bios update I check r23 to make sure it didn’t kil my uv. But from what I can tell, all of my issues have been with Awcc and how it interacts with the bios.
