Hello, I have a Toshiba Satellite C50-b-14h laptop and I want to upgrade my RAM, it has DDR3L, 2 GB, 800 Mhz RAM in now. I want to upgrade it to 4 or 8 GB (8 GB is the max supported) but I also want to buy ones that are faster aswell but I can't find anywhere what is the max speed this laptops motherboard supports, the only thing I see in CPUID is that the manufacturer of the motherboard is Toshiba and the model is ZBWAA, Crucial site recommends me 1600 and 1866 Mhz RAM but I don't know how reliable that is cause Im really confused by now, official Toshiba site says this laptop has 1333 Mhz RAM but I have 800 Mhz, don't know what information to trust.
