    Just notice a new bios update for y740-15ICH, anyone tried it?
    Is the thermal still bad with the newer bios?

    Hello,

    My Y740-15ICHg had issues with the WiFi not working in Windows (Device manager showed a network controller with a yellow exclamation mark and had correct VID & PID values but just couldn't install the driver and make it work) in Ubuntu I could see the 9560 show up in lspci but over there also the card didn't work.

    I then updated the BIOS to 1.12 and it came back up.
    ----------------------------------

    Also, has anybody upgraded to the AX200 or better? I wanted to know which card works as there is BIOS whitelisting with Lenovos.

    I updated the BIOS and run my CPU at -125mV core and -100mV cache. Saw no difference in CBR15 scores (1050-1130) with multiple runs in a room with high ambient temps(27c).

    What about the temps? About the same than before?

    Temps are the same for me. Specifically my CPU constantly sits between 90-95 degrees and sits at 95 when under heavy load. Often when starting up/general use it will spike to 90-92. Now that I've had this laptop for more than a year I am going to be re-pasting.

    Can you verify that the undervolts are actually getting applied in Throttlestop? Open the FIVR menu and look at the top right table, you should be seeing the offsets changing.

    That's definitely applying correctly. Reason I asked was that they didn't for me when I first tried it.

    Unfortunate, but you can definitely try repasting.

    It hasn't really bothered me, the only time its irritating is when I am not doing much and the CPU just spikes every now and again and forces the CPU fan to max out. I'm more concerned of the health in a years time with the CPU constantly sitting at 95 degrees under any sort of load.
