Server RAM – FAQs

How do I know if my server supports a specific memory module size?

To check if your server supports a given module size (e.g., 64GB, 96GB, 128GB, or 256GB), refer to your server’s technical documentation or use our compatibility filters. Key factors include:
– Maximum memory per slot and total system capacity
– Support for RDIMM vs LRDIMM
– Memory rank limitations (e.g., dual, quad, octa)
– Voltage and speed compatibility (e.g., 1.2V DDR4-3200 or 1.1V DDR5-5600)
If you’re unsure, our team can help you verify the best match for your system — get in touch with support.

How do I choose between DDR3, DDR4, and DDR5 for server memory?

Choosing the right memory generation depends on your server’s hardware compatibility and performance needs. DDR4 and DDR5 provide faster speeds and improved energy efficiency compared to DDR3, making them better suited for modern workloads like virtualization, high-performance computing, and databases.
See our guide DDR3 vs DDR4 vs DDR5 Datacenter Memory Comparison

What is the difference between RDIMM and LRDIMM server memory?

RDIMMs (Registered DIMMs) are commonly used in standard server setups, offering solid performance and reliability. LRDIMMs (Load-Reduced DIMMs) are designed to support higher memory capacities and better signal integrity, making them ideal for memory-intensive workloads such as virtualization, large databases, and enterprise applications.

Is ECC RAM necessary for server configurations?

Yes, ECC (Error-Correcting Code) RAM is strongly recommended for most server environments. It helps detect and correct bit-level memory errors, improving system stability and reducing the risk of crashes—especially in applications involving virtualization, databases, or mission-critical workloads.

What do memory ranks (dual, quad, octa) mean for server RAM modules?

Memory rank refers to how DRAM chips are organized on a server RAM module—common types include dual-rank (2R), quad-rank (4R), and octa-rank (8R). Higher-rank modules typically allow for more memory per DIMM but may also introduce additional latency and power consumption. These ranks can impact performance, density, and platform compatibility, depending on the server’s CPU and motherboard.
