I have 8gb ram currently in my desktop and I want to to buy another 8gb stick to make it run in dual channel since my ram has been maxing out a lot in games. I can't buy the exact same model because it's ram from Dell and they are charging $110 for one 8gb stick which is bs. So what do I have to make sure my other ram stick has so that it can run dual channel with my current ram? I heard of things like Cas latency, speed, voltage, etc. The picture below is my current ram specs from cpuzhttps://imgur.com/a/CS3gMSV
