Description
NEMIX RAM memory upgrades for the QCT QuantaGrid D43N-3U: DDR4-3200 PC4-25600 ECC Load-Reduced (LRDIMM) modules, 64GB to 128GB, sold as single modules and matched kits of up to 16, selected as drop-in, compatibility-tested replacements. 1.2V, 288-pin, JEDEC-compliant.
The QuantaGrid D43N-3U is a 3U dual-socket GPU server for AMD EPYC 7003 series processors. It has 32 DDR4 DIMM slots and supports up to 2TB with 64GB RDIMMs or 4TB with 128GB LRDIMMs. QCT lists DDR4-3200 memory, the native speed of AMD EPYC 7002 and 7003 processors; it can run at 2933 MT/s on some processors. This server takes DDR4 ECC Registered (RDIMM) or Load-Reduced (LRDIMM) memory; do not mix RDIMMs and LRDIMMs, and unbuffered UDIMMs will not work. LRDIMMs are the route to the highest capacities. Install identical modules in matched sets, populating the slots in the order QCT gives for each processor, and use one module size throughout.
Researched, matched, and compatibility-tested by NEMIX RAM, a US-based server memory specialist since 1993, and backed by a lifetime warranty. Purchase orders, net terms, and volume pricing are available for fleet refreshes and data center upgrades of QCT servers; contact our sales team for a quote.
