How to modify the laptop BIOS to allow it to recognize larger onboard memory

[金生水]

How to modify the laptop BIOS to make it recognize larger onboard memory chips? For example, the motherboard schematic diagram of this laptop shows that it supports 16g. I want to replace its onboard memory chips with 32g. How to modify the BIOS to make it recognize 32g? Which teacher can help me? Thanks

can not be done. (laptop bios are notorious for no options to be adjusted.)

the bios tends to re-configure itself when you put more memory into the motherboard. on laptops with removable memory, sometimes you can do that. I had a laptop that had only single channel memory in it, (it was slow). Can’t remember if I just added one stick or added two sticks, in any case the micro processor and the bios recognized both sticks and made it dual channel, allowing the 3D mark benchmark to be 33% higher.


if the schematic says it only supports 16 gig, that means it can only address that amount. so it is academic that you can replace it with 32 GB.
now, if there was an option on the manufacturers website that you could order it with 32 GB, then you would have a chance.

as an aside, I’m amazed that they (asian countries) can actually take an iPhone and swap out the storage chips to make it larger… (in a store no less!) think you can do that is possible because the iPhone can be ordered with that size.

Due to new signed bios requirements unless laptop is older (Like Intel 9th gen era or older), you may be unable to do this even considering bios mods, sorry.

Hello, I am an electronic equipment repairman. I'm talking about the fact that the onboard memory is upgradeable. For example, if your laptop has 8G of onboard memory, it can be upgraded to up to 16G on the factory drawing. In this way, you can replace the 16G memory particles by replacing the identification resistor on the circuit. However, the CPU of this laptop can support up to 32G, so you need to modify the SPD file in the BIOS to identify this 32G memory particle. Also, as you mentioned, if the memory of the iPhone and iPad is 128G, then it is easy to upgrade to 256G, 512G, 1T, 2T. I also mentioned before that I wrote it using translation software, and there may be inaccuracies in the translation, I hope you can understand more. Thank you.

no problem. particles equal memory chips.

i do not know how do answer your question, my knowledge is limited to “ if I can remove it with my hand” I can fix it. (or i have a chance)

i limit of my skill is changing the joysticks in a ps5 controller with TMR sticks.

i am sorry that i am not knowledgeable, i can not answer your question.

The BIOS will recognize the installed memory during initialization as it probes all of its memory address as long as the memory is compatible.

All devices are seen as just memory addresses by the CPU at the hardware level.

thank-you, basically what I was trying to say, but you said it better.

Might need a hex editor to do it, also the bios signature/checksum might keep it from being modified.
