Require LPDDR4 compatible only with DDR4 type.
I aim to modernize my old Acer laptop from its current DDR3 4GB memory to an 8GB setup, but only with a single memory slot. After removing the back cover, I noticed there’s just one slot available—why does Acer have this design? I’m searching for LPDDR4 RAM options, but all results point back to standard DDR4. The Intel Pentium N4200 supports up to 2400MT/s and 8GB LPDDR4 on their website. I’m wondering if a regular DDR4 1x8GB module would work, since I can’t find LPDDR4 RAM in the Southeast Asian market. The attached photo shows the existing LPDDR3 or DDR3L modules rated by the Arc system.
I haven't encountered LPDDR3 SODIMM before. I've only worked with LPDDR4 SODIMM.
The CPU's memory controller can handle DDR4, but your laptop's motherboard is set up for DDR3. A straightforward replacement isn't possible. If you're comfortable with PCB design and reverse engineering, you might be able to create a newer motherboard using DDR4 components by replacing other parts, though this is beyond the average person's expertise.
Sure, I appreciate the idea, but it doesn't seem worthwhile. The better choice would be to keep using the current DDRL3 and upgrade to an 8GB version.
It means that the CPU can support either DDR3L or LPDDR4 but that is "SUPPORTED", doesn't mean that a motherboard can support two different RAM "styles". That means if your computer has DDR3L, you are stuck with it. Same would apply if your computer had LPDDR4. There's is no such thing as one motherboard supporting DDR3 and DDR4 or DDR5 at the same time, it's simply not a thing.
I understand the mix-up. DDR3 and DDR3L refer to the same type of RAM, but the latter is designed to operate at lower voltage, which affects power usage. LPDDR is unrelated and not soldered in SODIMM form. The numbering system doesn’t match regular DDR, so look for DDR3L modules instead. No connection to LPDDR in any form.
