    I just got the 15 oled YD with the 11th gen intel and rtx 3080. I repasted the chips with liquid metal and changed to fuji pads. I have the thermal head room for an upgrade on the wattage for the gpu and I want to use the balistix ram that has 16CL timing at 3200. So i need an unlocked bios for mem times and some undervolt and a vbois for the gpu for more power. can any one help? My current bios is FB03 Id prefer if some already has an unlocked bios that i can just flash verses trying to mod an existing one.

    You might want to check winraid forum for this. Theres a huge thread of request for aero laptops.

    I got the KD version and was thinking of using liquid metal, but from experience liquid metal dries up within 3 months if using with a copper surface. Are aero heatsinks using bare copper surface or nickel plated? If copper, you should be careful and monitor it after a few months.

    You have to repaste after a few months because copper with drink it, but it only happens after the first application. after you repaste the second time u are good

    Or you could use a high-quality traditional thermal paste like Gelid GC Extreme or Phobya Nanogrease. They may not be as effective as LM in absolute terms, but they're basically "set it and forget it."

    I got my bios unlocked with help from winraid gurus. Unfortunately there is no option to change the nvidia gpu tgp in bios. Seems it needs a vbios mod.

    The most important thing from the unlocked bios is the ability to undervolt. Disabling overclock lock allows throttlestop and XTU voltage control to work, and multiplier control. Supposedly it can go up to +4 multipliers from stock multipliers. But I haven't seen it actually clock higher. I only tested on 1 and 2 core turbos in bios and XTU. If I set one core to 49 or 50x mult, the system locks up and crashes right away. Probably something else that needs to be set here for this to work. Need to look into further. -50mv undervolt seems stable and my cinebench r20 score went up by 300 pts due to it being able to hold turbo longer. -75 and -100 turned out unstable.

    Second thing is the memory. At stock, the memory clocks and timings seem to change dynamically. Hwinfo shows consistent clock but changing timings. CPU-z shows changing clocks and timings. Both utils probably cant read this system correctly at the moment. During memory benches, Ive seen the clock and timings go to 3200CL22. In the unlocked bios, if you turn on overclock mode, it forces the ram to always run at 3200CL22 which is the XMP profile. Now the weird thing is, the latency actually tanks compared to the dynamic clocks stock setting. Ive tested with aida64 and passmark and get consistent results. Even when I set it manually to 3200 21-21-21, I actually get worse latency than 3200CL22. So something is weird here... I just leave it on stock settings for now.

    I got Aorus 15P YD

    When i was undervolting CPU it looks stable at -75mv in testers/apps. No errors for few hours etc.
    But when i started heavy gaming it sometimes crashed the system.
    At the end i ended at -55mv core and -55mv cache

    For GPU 3080RTX I ended at overclock 190 Mhz.
    For games because laptop thermals I locked V at 700 mv giving me 1500Mhz stable running all the time.

    Now it is stable for 2-3 weeks. No single problem.

    I also bought cooling pad last week Thermaltake Massive V20.
    It allows laptop to suck more air from bottom.
    That helped all my temps when doing prolonged burn tests (1h+) CPU+GPU at the same time.
    The difference is at least 5C down.
    CPU is running 1 tick upper with fans OFF.
    When I set fans ON it doesn't make big difference. Maybe 2-3C less.

    Yesterday I also set ram from 3200 22-22-22 52 to 3200 20-20-20 44 and run all night burning test.
    Looks god for now but we will see when i will start gaming.

    Repasted mine with spare noctua paste and slight 2-3C improvement on CPU. GPU was actually 1C worse... Fiddling around some more, and the biggest thing was undervolting the 3060 gpu. Have a custom curve in afterburner and getting ~1750mhz @ 0.8volts. It has lowered the power consumption on the less demanding games by up to 30 watts and temps by 10-15C. In rdr2, it can sustain 1750mhz with 1440p dlss ultra, and it won't reach thermal throttling temps anymore which is ~87C.

    Was gonna try one of the 100watt vbios from the aorus, but now I realize theres no way this small thermal setup can cool the extra 10watts, unless I switch over to liquid metal. Since its brand new, I might just wait a half year or year before I do that, knowing I will need to sand down and reapply liquid metal probably two times to get it to be sustainable.
