64 GB DDR4 LRDIMM for servers

This 64 GB DDR4 LRDIMM module is built for servers and workstations that require high-capacity ECC memory. It operates at 3200 MHz with CL22 latency and a 1.20 V supply. The dual-rank 288-pin design fits standard DDR4 server slots.

DID-agnostic supply simplifies procurement

Micron's DID-agnostic approach allows compatible modules from available inventory to be shipped under this SKU. This reduces stock-outs and delayed deliveries for partners who do not track specific design IDs. JEDEC compatibility ensures the module meets standard specifications.

DDR4 3200 bandwidth caps throughput

The PC4-25600 interface limits peak bandwidth to the DDR4 3200 standard. Systems needing higher memory throughput must move to a newer memory generation. Mixed DID inventory may vary in underlying silicon while maintaining JEDEC compliance.

Questions about this item

Will the 288-pin DDR4 module require any firmware updates or component replacements over its service life?

The module is a solid-state DRAM component with no moving parts or firmware; it does not require scheduled maintenance or replacement under normal server operation.

What electrical or thermal limit is reached first when the 64 GB LRDIMM runs continuously at 3200 MHz?

The module operates at a fixed 1.20 V JEDEC voltage; sustained loads are constrained by the platform memory-controller thermal envelope rather than the DIMM itself.

How much heat and power does the CL22 dual-rank kit produce during all-day server workloads?

At 1.20 V the 64 GB LRDIMM draws nominal DDR4 power and generates heat consistent with standard server memory; no active cooling beyond chassis airflow is specified.
