I was using what I had from tin of parts to keep Latitude 3330 running. Had 16GB DDR3L but I needed them to test and work on Latitude 3340 notebooks bundle that friend found in the dump bin.
So I put in DDR3L 2x2GB for short time (elpida). Worked at first... then finally crashed on sleep and wouldn't boot properly, corrupting the 1TB SSD. I kept trying to reinstall Win 10 OS, always deleting the partitions and recreating but still unbootable. Started over with pair of Samsung 4GB modules DDR3L 1600 and OS finally booted properly after reinstall.
Just watch for unexplained problems. Always don't trust the memory, keep some on hand, always replacing all and toss the untrusted memory out if that resolves your problem.
I always buy OEM brands that made them: Samsung, Micron/Crucial, Hynix, Elpida and few others. I don't keep generics.
I was doing computer repair for decades and knew what to watch out for these kind of sneaky problems. Hard drive is easy to tell, slow, buzzing, 2 beat ticks etc or totally unresponsive, laggy.
I would pull the hard drive and read the SMART attributes using any utility my favorite is gsmartcontrol. Only few MB to download and is windows only and takes seconds to check. But I can check any storage drives using this: PATA, SATA and SSD does have smart reporting, does not matter where storage drives came out of: Game consoles, computers etc.
I must confirm and show this to customers that drive had failed.
