Cisco Server Memory FAQs

What type of RAM is compatible with Cisco UCS servers?

Cisco UCS servers typically use RDIMM or LRDIMM modules meeting JEDEC standards. Always verify memory type and speed for your specific UCS model.

Can I mix RDIMM and LRDIMM memory in a Cisco UCS server?

No. Cisco servers require either all RDIMM or all LRDIMM modules. Mixing types can cause performance or boot issues.

Can I mix memory sizes or speeds in my Cisco server?

Yes, you can mix different memory sizes or speeds, but your server generally defaults to the lowest speed. Each module’s full capacity is typically recognized, but mixing can disrupt optimal performance. For best results, install identical modules (same size, speed, and type).

Do Cisco servers require ECC memory?

Yes, most enterprise‐grade Cisco servers rely on ECC (Error‐Correcting Code) memory to detect and correct data errors, ensuring reliability in mission‐critical environments. In fact, ECC is standard in many enterprise server deployments because it helps minimize data corruption and system downtime.

How many DIMMs should I install per CPU in my Cisco server?

The ideal number depends on your server model and workload. For best performance, follow channel balancing and optimal population guidelines—usually specified in your server’s documentation. Distributing DIMMs evenly across memory channels helps maximize throughput, efficiency, and overall system stability.

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

Yes. Most manufacturers allow memory upgrades as long as you use modules that meet the server’s official specifications. Check your Cisco server manual for approved speeds, capacities, and ECC requirements.

What are the benefits of upgrading Cisco server memory?

Increasing memory capacity and speed can boost data transfer rates, support more virtual machines, and reduce bottlenecks in data‐intensive workloads.

How fast can I receive Cisco-compatible memory across Europe?

CoreWave Labs offers fast dispatch in 1–7 days for Cisco-compatible memory modules across Europe.
