    Hey Ben, there's a nasty bug on this v28 when using stamp mode in performance tdp while plugged in on power. While it was fine with older bios, this bug makes the CPU overheat and throttles the machine at 8w, you can't even change the tdp through the button shortcut when that happens.

    Games that plays fine at locked 60fps at 20w with GPU sitting around 70°c are throttling when the GPU hits 85°C with stamp performance mode. I don't get why a light locked fps game would suddenly waste power and throttle the machine, a game shouldn't use more power at locked fps no matter the tdp set. That must be a bug.

    It does not happen on stamp performance tdp while on battery, only while plugged. Battery still retains the same 20w locked tdp.

    Thanks man! Great work on this product, keep up the updates.

  • I don't think it is just stamp mode, happened a few times in STT to me as well for some odd reason.
