[SOLVED] 3x8gb ram dual channel?

[Patrickibsen]

I got 2 old 2133mhz 8gb and i got a cheap 8gb hyperx 2666mhz ram from a friend and wondering if its worth to use all 3 or just keep using the 2x8gb

You could but often having ram with different speed/timings in PC can cause errors.

It wouldn't be dual channel, the other ram would be in a channel by itself.

unless you need 24gb, I would just stick with what you have.

You can't run dual channel with 3 sticks.

16 GB RAM is plenty for most tasks. I would go for the increased performance of dual channel and stick with using 2 sticks

That's Flex channel. What'll happen is you'll be running all sticks at 2133, the cpu will use the 16Gb dual channel as primary and if that gets used up will chase with the 8Gb in single channel.

So unless you use something that's so ram heavy that it goes beyond 16Gb of usage, there's 0 benefit to having the extra 8Gb in a slower configuration and the drawback of additional strain on the memory controller.
