Server Memory Upgrade

This 64GB DDR4 module is built for servers and workstations that require registered ECC memory. It suits administrators expanding capacity in Supermicro platforms or similar 288-pin RDIMM systems. Buyers needing unbuffered UDIMMs or non-ECC memory for consumer boards cannot use this module.

DDR4 3200 Registered Limits

The module runs at DDR4 3200 with a CAS latency of 22 at 1.20V. Registered buffering adds one clock cycle of command delay, so maximum throughput depends on the memory controller and population rules of the host platform. Systems limited to lower DDR4 speeds or lacking ECC support will not benefit from the rated frequency.

2Rx4 Micron Build Quality

Micron chips in a 2Rx4 organization populate the 288-pin RDIMM PCB. Supermicro certification confirms validated compatibility with qualified Supermicro motherboards. The registered interface requires a motherboard designed for RDIMM topology; it will not function in boards wired only for UDIMM or SO-DIMM slots.

Questions sur cet article

Should I pick the 64GB 2Rx4 module or a smaller single-rank stick?

The 64GB 2Rx4 dual-rank design fits systems that support registered ECC RDIMMs and need maximum capacity per slot, while single-rank alternatives typically top out at 32GB.

What does the DDR4 3200MHz CL22 rating mean for actual throughput?

At the rated 3200 MT/s the module transfers data at PC4-25600 speed; real-world bandwidth depends on the platform's memory controller and how many channels are populated.

How does the 288-pin RDIMM interface limit compatibility?

The registered 288-pin DDR4 form factor only works in server or workstation boards that accept ECC registered DIMMs; consumer desktop boards with unbuffered slots will not accept it.
