DDR4 RAM (Double Data Rate 4) is one of the most advanced technologies used in modern equipment. There are multiple varieties of DDR4 modules, segmented according to different properties such as physical size, capacity, speed, voltage, and specific applications. Some of the main types and variants are shown below:
UDIMM (Unbuffered DIMM):
- Common use on desktop computers.
- No buffer between memory controller and DRAM modules.
- They provide lower latency and are generally cheaper.

RDIMM (Registered DIMM):
- Common use on servers and workstations.
- They include a register (address and command register) between the memory controller and the DRAM modules.
- They provide greater stability and tolerate larger amounts of memory.

SO-DIMM (Small Outline DIMM):
- Common use in laptops, mini PCs and embedded systems.
- They are smaller in physical size if we compare them with the UDIMMs.
- They guarantee the same capacities and speeds as UDIMMs.

LRDIMM (Load Reduced DIMM):
- Use on high performance servers.
- Decreases the electrical load on the memory controller by using a buffer for data and addresses.
- Provides greater capacity and optimizes performance in configurations with many memory modules.

ECC RAM (Error-Correcting Code):
- Common use on servers and workstations donde la protección de los datos es crucial.
- Has the ability to detect and correct data errors.
- Available in variants such as UDIMM, RDIMM and LRDIMM.

Non-ECC RAM:
- Common use on desktop computers y laptops.
- It does not have sufficient capacity to detect and correct errors.
- It is more economical and sufficient for applications where error correction is not critical.

Gaming RAM:
- Developed particularly for gaming and overclocking lovers.
- They offer more powerful speeds and better latency.
- They often have heat sinks and eye-catching aesthetic designs.
Low Voltage DDR4 (DDR4L):
- Use on mobile devices and laptops for greater energy efficiency.
- Works at a lower voltage (approximately 1.05V to 1.2V) compared to standard DDR4 modules.
XMP (Extreme Memory Profile):
- Use in high performance and overclocking configurations.
- Allows users to automatically adjust memory parameters to maximize performance.
- Certified and compatible with specific motherboards.
These are the most common types of DDR4 RAM that you can find on the market. Choosing the right type depends on your specific needs, such as device type, intended use (gaming, work, servers), and desired performance needs.
