Hello everyone  
Please tell me about Acer Predator Helios Neo 16 PHN16-71-91QX (CPU i9 13900HX) original DDR-5 16GB RAM speed is 5600MHz. Upgrade to Crucial 64GB Kit (2x32GB) DDR5-5600 SODIMM
CT2K32G56C46S5. My laptop cannot support DDR5 5600MHz. Does anyone know what happened? Thank you all

    This is what Acer states for your laptop.

    and this:

    So your i9-13900HX CPU supports 5600MHz speed but up to 32GB maximum RAM, you installed 2x32GB modules while only 16GB per socket is supported. Maybe you can exchange the modules for 2x16GB DDR5. Alternatively buy one identical 16GB DDR5 module that matches the original 16GB DDR5 in every detail (brand, CL, rank, etc.) and try to return the 2x 32GB modules to Crucial.

    I understand thanks for your explanation, currently using 64GB 4800MHz etc. ACER issues new BIOS update

    We jointly request ACER to open the BIOS update to support 5600MHz, otherwise the performance of this laptop will be wasted.
