I'm intending to upgrade the 8gb ddr4 ram in my Aspire xc-895 to 32gb using a 2x16gb kit. More than likely Corsair Vengence. There are lots of different speed option 2400mhz, 3000mhz, etc. I'm not sure if there are any specifics I need to pay attention to? I don't want to get caught out buying a kit that will have compatibility issues or just be wrong. Any advise would be greatly appreciated.
