Hello fellas
I have a doubt about RAM upgrade for the E1-421
I have the E1-421-0-BR899 (brazilian version) here, it has 4GB of RAM, 320GB HDD and E1-1200 (1.4 GHz) processor
I upgraded my HDD to a 1TB hybrid and removed the slim DVD and replaced with a HDD SATA caddy (750GB HDD)
But I got a doubt about RAM upgrade here
Acer says it can handle up to 8GB (2 x 4GB) RAM here, but does anyone know this is the real limit ? I know brands use to say this as a "safe" limit, since I also have an Acer netbook here (AO722) that has an official 4GB limit, but I searched forums when I bought it and people could use a 8GB memory with no problem, and I bought a 8GB memory to use there, and it worked really fine 
So... is it possible to use 16GB (2 x 8GB) with this notebook ? The only problem here is the RAM issue, since its pretty much fast even with the bunch of stuff I install and the number of HDDs I use with my USB 3.0 hub ehehehe
Tks !
