Macbook bios relationship with memory size

02-10-2021, 12:16 PM

hi. have had some requests for memory upgrade of soldered lpddr3 memory on macbooks. we are interested to perform this surgery (ie. remove the 178 ball BGA memory x 4 and replace them with the higher density lpddr3 devices, change the resistor straps to suit).

however, confused on the youtube video (REWA) that notes that the bios must be changed as well due to the upgrade procedure.

let us say we wish to upgrade the a1502 to 16gb - do we need to reflash the bios to a specific version to support this upgrade?

please see here:

ASUS TP500LA BIOS request/repair/merge?

by jbonavita

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized

Things I tried

1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

[REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock

by zenius

Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
