Memory support

The concept of memory rank applies to all memory module form factors, though in general it tends to matter primarily on server platforms, due to the larger amounts of memory they manage.

Voltage refers to the power consumed by a module. In the past, most DDR3 memory voltage ranged from 1.5 - 1.65v. More recently, dual 1.35/1.5 voltage modules came available at Crucial.com.

The density of a memory module is determined by the small black DRAM chips that make up the memory module. The fewer chips there are on the module, the higher the density.

If you have never purchased or installed memory for a server or workstation, there are additional considerations above and beyond that of normal desktop and laptop computers to keep in mind.

Questions and answers about the new DDR5 RAM technology.

A small number of DDR5 systems and motherboards require a period of "training" newly installed memory to work with the system and allow access to the UEFI, or otherwise to complete the system's power-on self-test (POST).
