Hello and good day, everyone.
I have an old Asus Eeepc 1215cx, i have trouble with how to change the soldered ram detail and capacity in BIOS in order for the BIOS to recognize the new soldered RAM completely.
Old RAM is Elpida EBJ20UF8BCS0-DJ-F with J2108BCSE-DJ-F Chip
New RAM is Samsung M471B1G73QH0-CH9 with K4B4G0846Q Chip
I’ve been researching for about 2 months, and by looking at the product page, I found that both of those chips have identical electrical paths, pin-by-pin, and many other things.
I already unsoldered the old RAM chips (J2108BCSE-DJ-F) and desoldered the newly bought samsung RAM in order to get the K4B4G0846Q chips.
My next step is modding the bios so that the BIOS recognizes the new chip, but i’m struggling to do it because i dont know what to change in the bios.
I already extracted the bios bin file through CH341a programmer and opened it through uefitool and AMIBCP.
I found out that the Hex for memory is 4D 65 6D 6F 72 79 and located it in the UEFI tools.
Do anybody know anything regarding the next step ?
Thank you so much for your time, any help will be greatly appreciated.
