Server RAM & Memory

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.

RDIMM, LRDIMM or UDIMM: which DIMM type do you need?

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.

RDIMM (Registered)
A register buffers the address and command lines, so the memory controller sees one load per DIMM. The standard choice for most 16GB-64GB modules in ProLiant, PowerEdge, ThinkSystem and Supermicro servers.
LRDIMM (Load-Reduced)
Buffers the data lines as well, which lets a channel carry more, larger modules at full speed. Used for 64GB-512GB high-density builds where total capacity matters more than per-module cost.
UDIMM / ECC UDIMM (Unbuffered)
No register - the controller drives the chips directly. Found in entry servers, workstations and micro-servers (Xeon E, some AMD platforms) with two DIMMs per channel at most. Not interchangeable with RDIMM.

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

What's the difference between New, Recertified and Refurbished drives?+

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.

Do you accept purchase orders and volume pricing?+

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.
