Tight Supply – DDR4 Server Memory on Allocation

Micron

16GB DDR4-3200 ECC Registered DIMM, 2Rx8, 288-pin, 1.2 V – Micron server memory on allocation

The Micron MTA18ASF2G72PDZ-3G2R1 is a 16GB DDR4-3200 registered ECC DIMM (PC4-25600, CL22) built as 2 ranks x 8 using Micron’s R-revision 8Gb DRAM, in the standard 288-pin, 31.25 mm RDIMM form factor at 1.2 V. It is a widely qualified module for Intel Xeon Scalable and AMD EPYC server and workstation platforms still in production and in the field. With DRAM fabs prioritizing DDR5 and HBM, DDR4 server modules in specific qualified revisions have become difficult to source through authorized channels, and data-center and OEM buyers are turning to the open market to keep installed platforms running. Cerametronics sources MTA18ASF2G72PDZ-3G2R1 and compatible revisions with full traceability and quotes within 24 hours.

Quality & Traceability

Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.

FAQ

Why is a DDR4-3200 16GB RDIMM in short supply?
DRAM makers have shifted wafer capacity to DDR5 and HBM, so DDR4 server modules – especially specific Micron revisions that were qualified on existing server platforms – are produced in smaller volumes and see allocation and price spikes. Data-center operators and OEMs maintaining installed DDR4 platforms buy matching revisions from the open market.

Does the DRAM revision matter when buying replacement RDIMMs?
For mixed populations it usually does: many server qualification lists specify the exact Micron part number including the revision suffix (-3G2R1 vs -3G2E1 / -3G2E2). We quote the exact revision you request and provide module labels and lot information before shipment.
