    There are NO options in BIOS to overclock the ram in these laptops. The PH315-55 laptops 12th Gen cpu has a max total ram limit of 64GB @ DDR5-4800MT/s speed ONLY you CAN NOT put DDR5-5600MT/s as this ram will run at 4800MT/s speed or not run at all and your laptop will not boot, don't take the chance. So be very careful and only fit the compatible ram for your PH315-55 model laptop,

    If you want 64GB kit use this Crucial kit only DO NOT use DDR5-5600MT/s CL46 type ram.

    Crucial 64GB Kit (32GBx2) DDR5-4800 SODIMM

    • CT2K32G48C40S5
    • Configuration ID: CT23902450

    DDR5-4800 • CL=40 • Non-ECC • SODIMM • 262-pins • 1.1V • 2Rx8 based • PC5-38400

    This is the Acer ram that was tested with your PH315-55 laptop, so use this type of ram also:
