What does "registered" memory module mean?

The term "registered" refers to how the memory module processes signals. Registered modules contain a register that delays all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.

While most PCs will accept only unbuffered memory modules, there are some that accept registered memory modules. Keep in mind that when you install registered memory modules, all of the modules installed in your PC must be registered because unbuffered and registered modules are not interchangeable.

You can tell if you are using registered memory by looking at one of the modules currently installed in your system. If it has one or more small black chips mounted horizontally on the module, you have registered memory. If not, you have unbuffered memory.

If you are not sure whether your motherboard or PC supports registered memory modules and it is not listed in our Memory Selector, please contact us. We would be happy to look into it for you.
