I have some 2933 mhz ddr4 ram as a result of upgrading another laptop. I have 2 sticks of 8 Gb 2933 mhz DDR4 laptop sized memory. This is used to upgrade the performance of many laptops. You'll need to make sure that your laptop supports this RAM. I can help you make sure the laptop you want to use with this is compatible and I can help you install it as well if you like (for free, as long as your laptop has a decent way to access it and does not use soldered memory. If it uses soldered memory, it's not a good idea to change the ram). This is a good way to increase the performance of a compatible laptop and give many laptops access to dual channel memory. $50 for both sticks obo $30 for a single stick obo (I strongly suggest using two sticks of the same type of RAM)
