hala Ahmed .. I've no idea if u can dumb and flash ur whole bios .. and yes its the same GPU so it should work. but keep in mind that HP is poor at cooling so u should keep an eye on the thermal management or u will end up fried ur motherboard

its really simple u just need these tools :

-AFUwin64 to dumb ur bios and flash it later

-Mmtool to extract ur bios and edit it and replace it back

-maxwellbios tweaker: to manage ur clocks

hi i'm kinda new to this thing,can you pls make a video and show me the whole process step by step because i couldn't understand the whole process from just the comments,my laptop is also asus x550j and need to higher clock speeds but more importantly i need to undervolt the gpu so that will slight performance but more importantly run cooler because whenever i hit 80c the clocks go down to 405mhz which will automatically crash any game in mid game or even at the start,pls i need help,and pls reply back if you can send a video to my email,i can then confirm you're available and give you my email
