Server Memory — DDR5 ECC RDIMM, LRDIMM & MRDIMM

Moyan Technology is a wholesale supplier of DDR5 ECC server memory for AI and datacenter platforms — Registered DIMMs (RDIMM), Load-Reduced 3DS LRDIMM, and next-generation MRDIMM — in densities from 16GB to 256GB. We source from the three DRAM makers and the Taiwan and China module houses that assemble their dies, and quote in bulk with indicative market pricing.

Server RAM is in an acute, AI-driven shortage as of 2026: prices are up sharply year-on-year, lead times run long, and high-density and high-speed parts move on allocation. We track the market and confirm live figures at RFQ.

What we supply

RDIMM — 16GB to 96GB, DDR5-4800 / 5600 / 6400.
LRDIMM 3DS — 128GB+ high-density for large-memory nodes.
MRDIMM — first-gen 8800 MT/s for Intel Xeon 6 “Granite Rapids”.
High-density — 256GB modules for memory-bound AI inference hosts.

Modules, speeds and indicative prices are in the catalog table on this page (stamped “as of” a date; confirm live at RFQ).

FAQ

What is the difference between RDIMM, LRDIMM and MRDIMM? RDIMM registers address/command signals for stability; LRDIMM (often 3DS) buffers data for the highest densities; MRDIMM multiplexes ranks for more bandwidth (8800 MT/s first-gen). We match the type to your platform.

How much is 128GB or 256GB DDR5 RDIMM? Prices move weekly in the current shortage. See the indicative range in the table and confirm live at RFQ.

Do you supply memory validated for EPYC and Xeon? Yes — we confirm compatibility with Sapphire/Emerald/Granite Rapids and EPYC Genoa/Bergamo/Turin platforms.

Can you support a long-term agreement? Yes. For volume programs we work with module houses on LTA-backed supply to hedge shortage risk.
