PROmem4I am having trouble finding some good replacements for my good old laptops. They are all original Dell and Mac laptops and when I tried buying them generic spare parts, they just wouldn’t work properly as expected. I thought my laptops were good as gone but still I had them taken a look at at that’s where I found out then as the technician said to me that I needed to get some original Dell memory as the laptop’s RAM memory configuration would not accept any generic branded memory. And for the mac laptop, he told me that all I simply needed was a higher ram Mac memory as my laptop was having a hard time coping up with all the programs installed. Good thing I know of a good site online to purchase exactly what I needed, it was in www.memoryupgrade.pro.
