    Macbook bios relationship with memory size

    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:

      🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
      by macabook
      Hello everyone,

      I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
      🧩 Initial Issue
      • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
      • External display (HDMI) shows

      [Problem/ Request] Bricked TongFang GK7MRFR BIOS
      by cr4zychriss
      Hello everyone,
      I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
      I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

      ASUS Zenbook Pro Duo UX8402ZA BIOS
      by pirati
      Hello everyone,

      I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

      When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

      I decided to try flashing a new BIOS, but since I didn’t want to desolder...
