I have a HP Notebook with 8GB of ram and I want to upgrade to 16GB instead of purchasing a new computer. The reason for my upgrade would be to utilize more memory on my computer as I have added new gaming apps. I was wondering where should I go to get the upgrade? However, I was thinking maybe it will be cheaper to do it from home, but I need help finding the right ram products to do the home install.. The laptop model is HP Notebook - 17z-ca000 CTO. Please some help me.
