Anyone know how to adjust the memory settings in BIOS or an app? DRAM Frequency should be 1333MHz.

    Hi,
    What is the speed of the other module in your laptop? If it's 2400MHz, the DRR4 2666 MHz module will downclock to 2400MHz.

    Kingston Technology HyperX Impact  8GB 2933MHz DDR4 CL17 SODIMM Memory HX429S17IB2/8
    The system also runs at 1200 when only the original 2666 is installed, rather than 1333.

    Hi,
    DDR4-2666 is compatible with your model but I don't know why it works at 2400, could be the BIOS limitation. HyperX Impact may be not compatible with your laptop.

    Thanks for the info. You are right, still do not understand why the Acer provided DDR4 2666 is not running at speed. I was unable to find any advanced BIOS settings.

    Acer support solved my issue. Task Manager Performance correctly reports running at 2666 (1333MHz). CPU-Z may need to be updated to accurately read 8300H processor, Intel® HM370 chipset and DDR4-2666 memory?

    Sorry to necro this thread. Running into a similar issue. Stock ram that came with my AN515-42 is 8ATF1G64HZ-2G6E1 8GB, a 2666 part. Performance programs indicate also running at 2400 instead. Contacted ACER support and they stated my model only supports 2400. CPU-world.com confirms memory control supports 2400 also.

    So why oh why was it built with 2666 ram inside???

    Yes it only supports 2400. Acer may have got a good deal on some 2666 and used them. The system specs say 2400 so it's no big deal if they installed a higher one, Acer didn't advertise 2666 as the spec ,it is just a logical presumption that it supports 2666 because that is whats installed

    Please click YES if I answered your question
