The chipset's specs don't matter here.

Start with the laptop’s official spec sheet, not the chipset datasheet. Laptop manufacturers often hardcode a lower RAM cap in the BIOS even when the chipset could handle more. Why? Heat, power, or just planned obsolescence.

Check the manual or the support page for your exact model. If it says “Max 16GB,” that’s your limit. No BIOS update will unlock it—manufacturers rarely add support for larger sticks years later. You can try installing larger RAM anyway (some laptops lie and actually work), but don’t count on it.

If you really want to know: install CPU-Z or HWiNFO and look at the “Max Memory” under the chipset tab. That’s the chipset’s theoretical limit, which is usually higher than what the BIOS allows. That gap is where you’re stuck. Manufacturers don’t publish which BIOS version removed the cap because they almost never do.

Don’t waste time hunting for a BIOS hack unless you’re on a forum for that specific laptop and people have confirmed it works. Otherwise, trust the sticker on the box.
