Genuine OEM enterprise drives · Fast US shipping · POs welcome
Server memory — the ECC, buffered DIMMs that keep production hosts stable. This hub covers our full range of enterprise RAM sold by exact manufacturer part number: DDR3, DDR4 and DDR5, ECC Registered (RDIMM) and Load-Reduced (LRDIMM), across 8GB through 512GB capacities and the common speeds, from Micron, Samsung, SK Hynix and the HPE and Dell OEM-serialized parts your iLO or iDRAC expects. Filter by capacity, brand and condition, or jump to a capacity page below. We list New and Refurbished stock together so you can compare a factory module against a tested pull for the same slot. Server memory is unforgiving about rank, voltage and OEM keying, so match your platform's population rules — or use the bulk-quote link and we'll confirm the part against your exact server model. Fast US shipping, warranty-backed, purchase orders welcome.
Server memory comes in three buffered/unbuffered designs. A server accepts only the type its population rules list, and RDIMM and LRDIMM can never be mixed in one system.
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.
Not sure which to pick? Read our New vs Recertified vs Refurbished guide.
New is factory-sealed with the full manufacturer warranty. Recertified is OEM-restored to specification with low power-on hours and our own warranty — the same capacity for a lower price. Refurbished is a tested, wiped working pull. All are sold by exact part number and warranty-backed.
Yes — we ship fast from the US and welcome POs. For quantity or a matched set, use the bulk-quote link on any product for pricing and a compatibility check.
