I have a Gateway DX4870 and it currently has 8GB and I was going to upgrade to the max of 16GB. First of all can someone tell me how to find out what motherboard is on here as no longer have support through Gateway. Also friend told me to do 4x4GB instead of 2x8GB. Went to Kingston site and memory finder says to use : DDR3, 1600MHz, Non-ECC, CL11, 1R, X8, 1.5V, Unbuffered, DIMM, 240-pin and this is single rank, but read somewhere that sometimes your motherboard will make you combine single rank w/ dual rank memory if upgrading to 16GB? Also is to upgrade to 16GB all I have to do is to install the RAM? Also I was thinking of buying 4x4GB, but can't I just purchase 2 more 4GB or should I purchase a total of 4 since not sure if totally will be the same as what is currently installed?
Thanks
