My mobo has two channels of memory. I have 2x16gb of corsair ram in there at 3200mhz. Would it be risky to buy another pair of 2x32gb corsair ram at 3200mhz? It's the same model but a different size, same speed too.
That motherboard allows up to 128gb of ram so you should be ok. But according to this, they are only recommending 8 to 16 of ram. Check your ram usage and see how much is being used when you are composing. I wouldn't upgrade unless you are using more then 80 percent of the existing ram.
