RAMmoduuli

RAMmoduuli, or RAM module, is an electronic component that provides volatile memory to a computer by storing data that the CPU can access rapidly. It consists of memory chips mounted on a small printed circuit board with a connector that plugs into the motherboard's memory slots. RAMmoduulit are available in several generations and form factors.

The most common types are DIMMs (for desktops) and SO-DIMMs (for laptops). Memory standards include DDR, DDR2, DDR3, DDR4 and DDR5, each offering higher speeds and vanishing voltages. Consumer modules are typically non-ECC (error-correcting) and unbuffered, while servers and workstations may use ECC and/or registered (buffered) modules to improve reliability and scalability.

Capacity varies by type and generation. Consumer modules commonly range from 4 GB to 32 GB per module, with higher-density modules available in high-end systems. Server configurations may use modules totaling tens to hundreds of gigabytes of memory.

RAMmoduuli stores data only while power is supplied; it loses contents when the system is powered off. The memory controller on the motherboard or CPU determines compatibility and maximum supported speed. BIOS/UEFI profiles such as XMP (for Intel) or DOCP (for AMD) can enable higher-than-default memory speeds if supported by the motherboard and module.

Proper installation requires matching form factor, ensuring correct seating, and avoiding mixing incompatible speeds or types, which can cause instability. RAMmoduuli has evolved to offer faster access, larger capacities and greater efficiency while remaining removable and upgradable.
