SK Hynix 8GB 1Rx8 DDR4-2400 ECC RDIMM Server RAM (HMA81GR7MFR8N-UH) - Used

SK Hynix 8GB DDR4-2400 ECC Registered RDIMM Server Memory (HMA81GR7MFR8N-UH) — Server Pull, Bench Tested

Genuine SK Hynix HMA81GR7MFR8N-UH 8GB 1Rx8 DDR4-2400T ECC Registered DIMM. Server pull from production datacenter infrastructure. Each module is bench-tested for POST, ECC functionality, and SPD identification before listing.

DRAM supply context: AI-driven demand has elevated DDR4 server memory pricing through 2026 and is forecast to remain tight through 2027. Tested server-pull modules at this spec deliver enterprise-grade ECC capacity at pricing well below the new-module retail floor.

What We Test on Every Module

• POST / boot test — module identifies and trains at rated 2400 MT/s
• ECC functionality — Error Correcting Code validated
• SPD verification — module reports correct capacity, rank, and timing to host BIOS
• Production provenance — pulled from a working server fleet

• Real production pulls — no relabeled modules, no unknown sourcing
• Fast US shipping — same-day or next-day handling
• Buyer-friendly returns — DOA replacements covered

Important Notes

ECC Registered (RDIMM) only — not for desktop systems. This module requires a server or workstation board that explicitly supports DDR4 RDIMM. It will not POST in standard consumer desktops or in motherboards limited to UDIMM / non-registered ECC.

Condition

Used — server pull. Tested working. Cosmetic blemishes and minor sticker residue from prior service environments are normal and do not affect function.
