I upgraded my laptop ram from 8 GB (3200 mhz) to 16 GB by installing a second ram 8 GB (3200 mhz), but after I installed the second ram, my laptop ram speed went from 3200 mhz to 2400 mhz. I already tried many codes I saw by searching for how to unlock xmp advance InsydeH20 bios. None of those codes are able to help me with my issue. I hope someone here can help me out to solve my RAM upgrade issue.

    You are using the wrong overclocked HyperX ram that is not compatible for this laptop, that is why when you add the 2nd ram module, the total ram speed gets downclocking to 2400MHz speed. If you want to increase this laptops ram capacity from its oem 8GB to 16GB Dual Channel at 3200 MHz speed you need to fit the exact spec 2nd ram module like the 1st module part number that is a DDR4-3200MHz CL22 standard type NOT XMP type ram. See the highlighted ram modules list below for all the compatible 8GB and 16GB DDR4-3200MHz CL22 from the AL15-51M SG laptop:

    Note: the ram above from CPUz the PART #: HX432S20IB/8 is a CL20 ram type and is not compatible

    Okay, now I understand. So, if I buy and install the 8GB 3200mhz CL22 to partner it with the pre-installed RAM 8GB 3200mhz CL22, it will run at its original ram speed (3200 mhz) without changing anything in the BIOS. Thank you for your reply!
