RAM: Unbuffered vs Registered?

Question

RAM

What memory is better and for what tasks???
For example, for a database server or a web server, which one is better to choose?
Thank you!
Z.Y. You don't need to copy from the wiki or anything else, I want to hear real examples and tests....

Answer 1

When asked this way, it doesn't matter.
Support for these types of memory depends on the hardware. Where reliability is required from the server, registered and the corresponding server hardware are used.
