mixing and matching buffered ECC RAM

[mrjayviper]

So I just found ECC RAM are extremely cheap. But the cheap ones I found comes in 6x4GB sets.

Is it possible to buy 18 sticks and then just get 16 out of the 18 sticks to be installed on the board?

All the sticks will have the same markings/model number/timings. Like RAM makers sell RAM sticks in pairs because they are guaranteed to work in pairs. And I'm just unsure if server board are very picky with these sort of things.

Thanks!

It all depends on the board in question.
It may / may not work.
It most cases, it should, as long as all the timings & voltages match.

Check your mb for supported config if you are mixing rdimm sizes.

Also, more stick = more power drawn.

Is buffered the same a s registered? What happens if you put registered ram on a mobo that's validated only for unregistered ECC memory?
