Hi everyone. I'm taking care of my uncle's PC, an old prebuilt Lenovo (should be IdeaCentre K430). I'm thinking of a couple of cheap upgrades, one of which would be adding a fourth stick of DDR3 RAM in order to switch to 16GB (4x4GB) full dual channel from 12GB (3X4GB) hybrid mode. Of course RAM looks like crap (brand is Sharetronic, Micron die if I’m not mistaken). I’ve found on the Internet a module with the exact same specs regarding speed (1600MHz), size (4GB), case latency (11) and voltage needed (1.5V), but the part number is slightly different, only for one digit, from the sticks I have, being SM311NQ08IAF vs SM312NQ08IAF. Could this difference potentially cause issues or can I safely assume that this fourth stick would be compatible with the others? Thanks in advance.
