Server memory uses ECC RDIMM and LRDIMM modules for the error correction and capacity that production workloads require. We stock DDR3, DDR4, and DDR5 server RAM matched to Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro platforms, in the ranks and speeds your CPU supports. Mixing or maxing out memory? We confirm DIMM population rules and per-channel limits so the upgrade posts correctly. Every module is tested and backed by a 3-Year Warranty.

Server memory is unforgiving about specifics: generation (DDR3/DDR4/DDR5), type (RDIMM vs. LRDIMM vs. UDIMM), speed, rank, and per-platform validation all have to line up. The reliable shortcut is your server model — every platform has a published memory matrix, and we stock modules validated against the major ones: Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, Supermicro, and Cisco UCS.
Memory upgrades remain the highest-impact, lowest-cost server improvement, especially for virtualization hosts where RAM — not CPU — is almost always the constraint. We carry capacities from legacy 8GB DDR3 sticks through 128GB+ DDR5 RDIMMs, from Samsung, Hynix, Micron, and OEM-branded lines.
RDIMMs (registered) are the standard server module; LRDIMMs (load-reduced) buffer data lines to allow higher total capacity per channel, at slightly higher latency and cost. Your platform’s memory matrix dictates which to use at your target capacity.
Only within strict rules — same generation and type, ideally same speed and rank. Mismatches downclock or fail to POST. Send us your existing part numbers and we will match safely.
Sum the allocated memory of your VMs, add hypervisor overhead (~5-10%), and leave headroom for growth and failover. We can sanity-check a build if you share the VM inventory.
