Hello All,

I would like to upgrade RAM for my inspiron 1564, bought back in 2010 jan.

I have checked that below is compatible RAM from crucial:

8GB Kit (4GBx2) DDR3 PC3-12800 Unbuffered NON-ECC 1.35V

I have question is only this one is compatible or there are others as Kingston/other ?

also is below also compatible for 1564 laptop?

Ballistix Sport 4GB DDR3 1600 MHz PC3-12800 Sodimm Laptop Memory 204 Pin
