I have a pair of DDR3 SODIMM RAM modules in my laptop, and I want to replace the 2GB for a 4GB that is compatible. So far I haven't been able to find an exact match but I found a very similar with a PC3L label instead of PC3. Can they work together?
My DDR3 SODIMM RAM:
Memory module in question:
Installed RAM: 4GB DDR3 2Rx8 PC3 12800S 11 10 F2
Matching RAM: 4GB DDR3 2Rx8 PC3L 12800S 11 10 F3
Laptop: Toshiba Satellite L645D-S4036
Is the converse true? My laptop has 4GB "PC3L" - 12800S RAM. Can I install 4GB "PC3" 12800S RAM to upgrade to 8GB ? – Navigator – 2014-07-10T08:02:45.137
Yes without any issue if your laptop mobbo supports the 1.5V on memory – Nikola Dimitrijevic – 2014-07-10T15:49:35.733
There's this excellent article on memory compatibility at Dell http://www.dell.com/support/article/us/en/19/SLN153768/en

@stt106 Did yours work? I'm finding myself at the same situation :) – David Refoua – 2019-03-13T14:15:05.173
1@DavidRefoua no, it didn't work. In the end I think it's impossible to tell by yourself whether a ram is going to work on your laptop/pc. I had to use a website that sells ram and only buy the ones it says it will definitely work on my pc. – stt106 – 2019-03-14T14:50:38.213
@stt106 Thanks for the update! I think that this is the type of information that should be covered somewhere in the manufacturer's documentation. Sadly those barely contain any information that could be practically useful. I guess it more or less comes down to trial and error. – David Refoua – 2019-03-14T15:45:49.007
Have several laptops of identical model, re-purposed them all. One gave an error on boot saying it had unsupported DDR3. Checked the RAM sticks/cards and discovered that the one that doesn't work is the only one that is PC3 rather than PC3L. – wolfsshield – 2019-05-30T18:11:50.307
