Recently, I bought 2x8 gb of Corsair 3000mhz RAM so I could have more in my system. I used to have 2x8 Ballistix 2133mhz RAM, but one of the sticks stopped working entirely. I purchased another single 8gb ram of the same model and took a gamble with it but they wouldn't work in dual channel. With the new RAM installed, I can have 24gb of RAM, but it underclocks the RAM to that of the older stick (2133 mhz). Otherwise I could have 16gb at a higher clock and having all the sticks be in dual channel. Which would be the better option? Also, is there a way to force the 2 older sticks to not run in dual channel so I could have all 32gb?
