that other RAM might be incompatible with your laptop.The best bet is to go to the hardware store and let them install and test the RAM before you it.
I doubt it. Back when this thread was started years ago, Endian was 32 bit and the ONLY way to get a 32 bit OS to see more than 4GB of ram is to have a processor that has PAE extensions and it has to be compiled into the kernel. These days since you responded years later to an outdated problem, one simply uses the 64 bit version and it's done in 2017.
