In this video, I go over the process of upgrading a Lenovo Legion Go handheld PC from its stock 16GB of system memory, to 32GB. Unlike in my previous attempt at upgrading the Steam Deck, I had to manually modify the SPD data in the system BIOS in order for it detect all the installed memory, rather than simply flashing a pre-modified BIOS image. The RAM chips can be purchased here (part number K3KL5L50CM-BGCT): https://www.aliexpress.us/item/3256805891971623.html APCB checksum script: https://github.com/95JakeHex/APCB_ROG_Ally/blob/main/Man_edit_apcb_checksum_fix.py If you'd like to have me perform this upgrade for you, you can contact me here: https://doslabelectronics.com/contact 0:00 Intro 3:05 Removing original RAM 5:41 Preparing new RAM 6:39 Installing new RAM 9:30 Initial test 11:32 Removing SPI-ROM 12:17 Modifying BIOS SPD data 28:03 Re-installing SPI ROM 28:49 Final testing and conclusion #lenovo #legion #upgrade
