Choose DDR2 or DDR3 RAM based on your system requirements and compatibility.
Your laptop is compatible with DDR3 RAM, not DDR2. You can upgrade to a DDR3 module for better performance.
Does it refer to Dell Vostro? The review mentions default DDR4-2133 support and also notes compatibility with DDR3L SODIMM, suggesting you might want to check cheaper options.
La open Task Manager will show you the exact CPU details. A better approach is to identify the laptop model... LOL that site made a big error... it mentioned DDR3 PC 3L 12800s is actually DDR3L 1600MHZ Sodimm. Generally, you can fit a DDR3L into a DDR3 slot, though the reverse might not always work. L means low power, and the lower power variant uses 1.2V instead of 1.3V or similar. And the 5th generation Intel uses DDR3. https://www.intel.com/content/www/us/en/...ell-h.html
This doesn't make sense unless there are two distinct laptop models. DDR3, DDR4 and DDR5 aren't compatible physically. If one system supports both, it would require dual sockets, which is highly improbable in a compact device.
I made a major error initially—it was a Dell Vostro, not a Lenovo, and I thought it had DDR2 RAM. After double-checking, it actually has 16 gigabytes of DDR3 at 1600 MHz. Now I’m wondering if it’s possible to upgrade to faster RAM, like 2400 MHz or even DDR4.
Not DDR4, it won't fit unless the laptop has a DDR4 slot. As you pointed out, it seems they have DDR3-1600, so I don't think a 2400MHz slot will work unless the motherboard is compatible. Dell officially lists a maximum of 1600MHz, but you can experiment with faster or larger RAM configurations. My Dell Inspiron 7720 SE only supports up to 8GB according to Dell, but I7-3610QM works with 16GB, and I've installed that successfully. Mixing DDR3 and DDR3L RAM has worked fine for me. You should check the exact CPU model you have and see what Intel recommends, then try that. Gen 6 supports DDR3L-1866 (PC3-14900) and up to 32GB.
They are not meant to work together physically because they use different pin configurations. Some processors can handle multiple types but require separate motherboards, which isn't possible in a laptop. You might get faster RAM, but performance depends on the motherboard and CPU. Overclocking options are usually very limited in laptops.
