I am feeling rather stupid at the moment, I have built a desktop from scratch so basic hardware concepts are not foreign to me, but I am having the hardest time understanding what the correct RAM to purchase for my particular laptop is. The laptop has 1 x 8GB stock, and I would like to purchase another 8GB stick to increase my total RAM to 16GB. I can simply add another stick to the existing one, and do not have to buy a pair of dual-channel, correct? I installed CPU-Z, and found some links online that appear to be the correct modules, but I was trying to find such an item on Amazon as I have a gift card I would like to use, and I am not having any luck.
Would someone be so kind as to link me the correct module to purchase from Amazon, or confirm that they do not sell any such module? And can anyone please educate me as to whether or not I am understanding the upgrade capabilities of the existing 8GB module?
Thank you very much in advance for your time.
