Genuine OEM enterprise drives · Fast US shipping · POs welcome
DDR4 ECC memory is the backbone of the current server fleet — Error-Correcting Code protects against single-bit faults, and Registered (RDIMM) or Load-Reduced (LRDIMM) buffering is what lets a server run many DIMMs stably. Every module here is server-grade DDR4 ECC, sold by exact manufacturer part number across 16GB, 32GB, 64GB and 128GB capacities and 2133 through 3200 MT/s speeds, from Micron, Samsung, SK Hynix and the HPE and Dell OEM-serialized parts your iLO or iDRAC expects. New and Refurbished stock sit together so you can compare a factory module against a tested pull for the same slot. ECC and buffering type must match your platform exactly — an unbuffered or non-ECC stick won't post in most servers — so confirm your population rules, or use the bulk-quote link and we'll pick the compatible part for your model. In stock, fast US shipping, warranty-backed, POs welcome.
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.

ECC (Error-Correcting Code) memory detects and corrects single-bit errors on the fly, preventing silent data corruption and crashes — which is why servers require it. Desktop (non-ECC) memory won't post in most server platforms.
Both are buffered ECC types for servers. RDIMM buffers address/command lines and covers most builds; LRDIMM also buffers data lines to reach higher capacity per channel. Use whichever your server's rules specify.
Generally no — most desktop boards need unbuffered non-ECC (or UDIMM ECC) memory and won't accept RDIMM/LRDIMM. These are server/workstation modules. Ask via the bulk-quote link if you're unsure about your board.
