Hi everyone, I have increased the memory of my Acer Nitro 5 AN515-55-55DW with a HyperX Impact HX429S17IB2/8 8GB 2933MHz DDR4 CL17 SODIMM bank.

Unfortunately the pc speed has dropped to 2663 mhz instead of going to 2933 mhz like before.

What can I do?

The CPU can handle 2933 mhz.

    Hi,
    You have mixed RAM modules with different profiles, your original RAM(SK Hynix) has JEDEC profile and the new HyperX RAM has XMP profiles and both have different speeds, you have to return the HyperX module and get another 3200MHz RAM with JEDEC profiles and install or buy another Kingston HyperX 2933MHz module and replace the original SK Hynix module.
    You can either have 2x8GB 3200MHz JEDEC modules
    Or 2x8GB 2933MHz Kingston HyperX modules.

    The CPU can handle 2933 mhz.

    When you say "The CPU can handle 2933 mhz" how do you know? Acer only recommends DDR4 2666/2933MHz for the AN515-55 if it runs the Intel Comet Lake-H CPU’s only and if it runs the Intel Coffee Lake-H CPU it recommends the DDR4 2400/2666 only? Which CPU does your AN515-55 have? Also, Hyper X is not a memory that is recommended by Acer (as brummyfan2 has said) so send it back and get new memory that is exactly the same spec as the DDR4-3200MHz (1600MHz) memory that is the OEM memory that came with your laptop.


    Also and as proof, your 2x memory tables are different, your new Kingston Hyper X runs at XMP-2666 at 1333 MHz frequency while the SK Hynix JEDEC #14 is at 1600MHz so the memory will always work in combination to the lowest speeds of 2x 1333MHz which is the total that you have given at 2663MHz.
