ram upgrade for Acer Aspire E5-521-24PQ w/1.5GHz AMD Quad
It has 4g of ram with an empty slot. Product manual says it can be upgraded to 16g. But doesn't tell me what kind of ram memory. I can only surmise that it will take 2-8gs of memory sticks. But what kind or brand?
pull out one of the sticks of memory and on one side it will tell you the Megahertz such as633, 800,1333,1066,1266.1600 etc.and the voltage does not matter with amd because amd will run with any voltage and since you are replaceing them it doesn't matterwhat it is,but on the replacements,it does use the same megahertz of the memory you are replacing,example if you had 1333mhz on the memory you are replacing, get the new 2- 8gb memory sticks 1333 mhz so fsb is the same and the timing {this is how fast it it such as 9-9-9-18 or similar} and the voltage will match.so the system will run same voltge,speed and mhz so there will be no system errors.I would recommend Corsair Vengence
