32GB Server Memory (RDIMM / LRDIMM)

32GB modules are the most-populated capacity in the enterprise fleet — the default DIMM for mainstream ProLiant, PowerEdge and Supermicro nodes where 32GB per channel hits the memory target at the best cost-per-GB. Every module here is sold by exact manufacturer part number: DDR4 and DDR5, ECC Registered (RDIMM) and Load-Reduced (LRDIMM), at 2400 through 4800 MT/s, from Micron, Samsung, SK Hynix and the HPE and Dell OEM-serialized parts your server's management expects. New and Refurbished stock sit side by side so you can compare a factory module against a tested pull for the same slot. Because rank, voltage and OEM keying all matter, match your platform's population rules first — or use the bulk-quote link and we'll confirm the exact part for your server. In stock, fast US shipping, warranty-backed, and purchase orders welcome.

New vs Recertified vs Refurbished

Every part is sold by exact manufacturer part number and ships warranty-backed. Here's what each condition means so you can weigh price against your workload.

New
Factory-sealed and unused, with the full manufacturer warranty. The safest choice for a fresh build or a warranty-sensitive deployment.
Recertified
OEM-recertified and restored to original specification, typically with low power-on hours. Health-tested and backed by our own replacement warranty — the same usable capacity for a lower price.
Refurbished
Professionally tested working pulls, wiped and inspected. A cost-effective option for labs, cold storage and non-critical tiers, warranty-backed.

Frequently asked questions

Is 32GB or 64GB better value per server?+

32GB usually wins on cost-per-GB and is ideal until you run out of slots; 64GB lets you reach higher totals without filling every channel. Compare your platform's max DIMM count against your target capacity.

RDIMM or LRDIMM for 32GB?+

Most 32GB modules are RDIMM (Registered), which suits the majority of dual-socket servers. LRDIMM matters mainly when you're maximising capacity per channel. Match your server's population rules.

Can I mix New and Refurbished modules?+

Match rank, speed and manufacturer across a channel for best stability. For a full matched set, use the bulk-quote link and we'll assemble one.
