DDR3

DDR3-RAM as a proven memory standard for servers and workstations

Even today, DDR3 RAM (Random Access Memory) is still a reliable and cost-effective way to expand the RAM of compatible IT systems. As a proven memory technology, DDR3 offers solid performance for servers and workstations that are to continue to be used and adapted to increasing demands. DDR3 memory is often a good choice for companies that want to extend the lifecycle of their existing hardware as much as possible and upgrade it as needed.

What types of DDR3 RAM are available for servers and workstations?

DDR3 memory modules are available in different variants for use in professional IT environments:

ECC & registered DDR3 RAM (RDIMM)

Designed specifically for professional IT systems, this memory offers integrated error correction (ECC: Error Correction Code), which detects and corrects memory errors. RDIMM modules are buffered, enabling higher overall performance in servers with many memory modules installed.

Load-Reduced DDR3 RAM (LRDIMM)

This type of memory reduces the load on the memory controller, enabling LRDIMMs to support higher memory capacities per module and allowing more RAM to be used in a system. This makes them ideal for memory-intensive applications such as virtualisation or operating complex databases.

Unbuffered DDR3 RAM (UDIMM)

Unlike RDIMM and LRDIMM modules, UDIMMs are unbuffered and are therefore suitable for servers and workstations that have to handle less demanding workloads. They offer lower latencies but are limited in terms of maximum memory capacity.

The technical characteristics of DDR3 RAM at a glance

DDR3 was developed as the successor to DDR2 and features several improvements:

• Higher clock rates with speeds up to PC3-14900
• Lower voltage of 1.5V for reduced energy consumption
• Higher capacity of up to 32 GB per module
• 240-pin DIMM slot

What should be considered regarding the compatibility of DDR3 RAM?

The DDR3 standard uses a 240-pin DIMM slot (dual inline memory module) that is not compatible with the older DDR2 standard or the newer DDR4 memory modules. A modified notch in the connector area ensures that DDR3 modules are not accidentally inserted into other memory banks. This prevents damage and ensures a clear distinction between the memory standards. Motherboards must explicitly support DDR3 RAM to allow an upgrade with these modules.

What are the advantages of DDR3 memory for servers and workstations?

In many IT infrastructures, DDR3 RAM is still widely used. Thanks to the high availability of used memory modules, RAM upgrades can be carried out cost-effectively to extend the lifespan of existing IT systems.

• Cost efficiency - used DDR3 modules are significantly cheaper than new memory technologies
• Reliability - ECC error correction minimises memory errors and provides reliable memory performance
• Sustainability - continuing to use DDR3 systems helps to reduce electronic waste
