The module of your RAM that is soldered is the one physically attached to the motherboard.
Check the RAM modules directly. Look at the labels or packaging for the specific model numbers. If you see a 2666 MHz chip, it’s the one that fits in the slot with that speed. You can also use a memory tester app to confirm the exact frequency without opening the laptop.
It seems there might be a misunderstanding, but the reason for soldering a RAM into a laptop isn't clear from your question. Could you provide more details?
regrettably not – numerous makers embed RAM and CPUs onto the laptop chassis, rendering upgrades impossible
The only solution is to open it and examine the RAM module directly. If the listed capacity isn't there, you can identify it by inspecting the chips on the sticks—typically you'll see a logo (such as Micron, Samsung, Elpida, Hynix, Nanya) and often a part number that reveals each chip's size (for example, 512 MB x 8 tiny chips equals a 4 GB module). I’d guess this laptop has a 4 GB RAM soldered, with an additional 8 GB stick for a total of 12 GB. This setup lets them market it as basic while actually offering more capacity. Usually, the RAM is 2666 MHz and is also soldered.
Have you looked at what CPU-Z displays regarding it in the SPD section? Typically RAM modules include a part number that you can search online to verify authenticity. I don’t understand how soldered memory appears in CPU-Z, but I assume it wouldn’t show a part number. For instance, here’s what the tab looks like on my laptop:
Thanks for the responses. I checked the RAM choices for these laptops and noticed 4GB is already soldered. Adding 3200 instead of 2666 seems confusing, maybe just limited selections. I think I’ll replace my current 8GB with a new 16GB module, bringing my total to 20GB. That should give me plenty of space for browsing, photos, and editing.
