Robert,

You say that dell supports mixing memory of different ranks. I have a T110 here with 2 x 2Gb 2rx8 installed.

I want to upgrade the memory with 4 x 4Gb 2Rx4. Server boots but the screen stay's black?

any idea?

Hello. Can I use Mixed RX4 and RX8 on my Dell R730 Server?

No, you can't. If you use together, the server will detect an error.

@Anonymous​ 

So, x4 has more banks than x8, or the opposite?

Because I see this answer to a question, that suggests the former, which is kinda counterintuitive:

If x4 is so much better than x8 (in performance, in reliability, in power consumption), why does x8 even exist? I don't think the price is much different, is it?

Hello thank you for your question. I am having a hard time giving you a one size fits all answer to this but I found some materials that may help your understanding further-

And if you could mix the memories- that is depending on the mobo you are using. But I would say the best way is to increase the total memory size regardless.
