Server Memory Upgrades — DDR5 & DDR4 RDIMM / LRDIMM

Q: How do I pick the right server memory for my system?

Start by checking your server manual or technical documentation for supported memory types, speeds, and capacities. You can also explore our dedicated server model pages to view detailed memory configurations and compatible options. Use our brand/model filters to match the right modules, or contact CoreWave Labs for expert guidance.

Q: Which DIMM Type Do I Need?

Most servers use one of three ECC DIMM types: RDIMM (Registered): Best for general-purpose servers. A register stabilises signals for reliable performance up to mid-range capacities. LRDIMM (Load-Reduced): Best for high-capacity, memory-bound workloads. Advanced buffering cuts electrical load so you can install the largest DIMMs available. UDIMM (Unbuffered): Best for entry servers or desktops. Lowest cost and latency, but scalability and stability drop off in large configs. Need a deeper dive? Read our full comparison.

Q: Can I mix different memory speeds and capacities?

Technically yes — but the system defaults to the slowest module. For best performance, always use identical DIMMs (same size, speed, type).

Q: Do I need ECC memory in my server?

Almost always. Enterprise servers depend on ECC (Error‑Correcting Code) to detect and fix memory errors, ensuring uptime and protecting data. Learn more in our detailed guide.

Q: How many DIMMs should I install per CPU?

Follow your server’s DIMM population guidelines — balancing DIMMs across memory channels maximizes throughput, efficiency, and stability.

Q: Can I upgrade my server’s memory without affecting its warranty?

Yes, as long as you use modules that meet the server’s official specs. Always check the manufacturer’s approved speeds, capacities, and ECC requirements.

Q: What are the benefits of a server memory upgrade?

More capacity and speed boost data transfer, support more virtual machines, and eliminate bottlenecks in data-heavy workloads.

Manufactured by Industry Leaders

We offer memory modules manufactured by Samsung, SK Hynix, or Micron— the very same industry‐leading suppliers Dell, HPE, Cisco relies on. This ensures each module meets high standards for performance, compatibility, and reliability, giving you genuine, equivalent quality at a competitive price.

Server Memory FAQs

How do I pick the right server memory for my system?

Start by checking your server manual or technical documentation for supported memory types, speeds, and capacities. You can also explore our dedicated server model pages to view detailed memory configurations and compatible options. Use our brand/model filters to match the right modules, or contact CoreWave Labs for expert guidance.

Which DIMM Type Do I Need?

Most servers use one of three ECC DIMM types:
RDIMM (Registered): Best for general-purpose servers. A register stabilises signals for reliable performance up to mid-range capacities.
LRDIMM (Load-Reduced): Best for high-capacity, memory-bound workloads. Advanced buffering cuts electrical load so you can install the largest DIMMs available.
UDIMM (Unbuffered): Best for entry servers or desktops. Lowest cost and latency, but scalability and stability drop off in large configs.
Need a deeper dive? Read our full comparison.

Can I mix different memory speeds and capacities?

Technically yes — but the system defaults to the slowest module. For best performance, always use identical DIMMs (same size, speed, type).

Do I need ECC memory in my server?

Almost always. Enterprise servers depend on ECC (Error‑Correcting Code) to detect and fix memory errors, ensuring uptime and protecting data. Learn more in our detailed guide.

How many DIMMs should I install per CPU?

Follow your server’s DIMM population guidelines — balancing DIMMs across memory channels maximizes throughput, efficiency, and stability.

Can I upgrade my server’s memory without affecting its warranty?

Yes, as long as you use modules that meet the server’s official specs. Always check the manufacturer’s approved speeds, capacities, and ECC requirements.

What are the benefits of a server memory upgrade?

More capacity and speed boost data transfer, support more virtual machines, and eliminate bottlenecks in data-heavy workloads.
