Hi @nick , I just upgrated my ASUS laptop (X401A based) with 8 Go of RAM (instead of 4 Go). Its processus does support 8 Go: https://ark.intel.com/content/www/us/en/...-pentium-processor-b980-2m-cache-2-40-ghz.html But I'm facing the following issue: The BIOS is detecting the whole RAM capacity: [código] ... But Windows 7 only uses half of it: [código] I don't understand why there is such a limitation. Any idea? UPDATE: I feel so dumb... Windows 7 32bits only support 4Go of RAM. This is such a pain to ugprade, and I'll have to put my old RAM back...
