    Hey! I have a Legion T5-26AMR5 Desktop (Lenovo) - Type 90RC pc and wonder if there are any way to increase the ram speed? I bought new ones that is Kingston Fury 32gb 3600 MHz but the speed is set to 2400 MHz in my BIOS. Tried to update my BIOS but i stil cant change the speed. Any way to do it?

    @momshuss Hello and welcome among us, in theory you should have 3200 Mhz (speed of RAM that comes with your tower).
    And from what I see (I don't there were an update since) but there is no option to set XMP / DOCP profile. Lenovo Towers are preconfigured

    Unfortunately, when no XMP option is available, the system can only support JEDEC speeds. The Legion AMD machines don't support XMP. Seems like maximum JEDEC speed on the memory you bought is 2400Mhz. If you can, just return that memory, as it's not compatible with your system in the way you want to use it.

    There's not much you can do about it other than figuring out if there is any memory on the market with better JEDEC speeds than you have (they cap at 3200Mhz for DDR4, but there can be tighter timings, marked as CL latency).

    For me, going from 3200CL22 to 2933CL18 was an upgrade.

    Hey!
    I’m in a similar boat with my setup, where I can't get my high-speed RAM to run at its advertised speed due to BIOS restrictions. It’s crucial to check if your motherboard supports XMP (Extreme Memory Profile), which allows for higher RAM speeds beyond the basic BIOS settings. If enabling XMP doesn’t work and you’ve already updated your BIOS, your motherboard might not support the higher speeds, which is common in some pre-built systems like the Legion T5.
    If you're stuck, reaching out to Lenovo support or looking through forums dedicated to Lenovo or Legion hardware might help. Often, community forums and tech support can provide model-specific advice or firmware updates to solve such issues. Good luck with getting your RAM to perform at its best!
