64GB DDR4 2933MHz ECC RDIMM for Servers
This 64GB registered DIMM uses Samsung chips and runs at DDR4 2933 (PC4-23400) with CL21 latency. It is built for Supermicro platforms that require ECC registered memory. The dual-rank 2Rx4 organisation suits high-capacity server configurations.
Installation Notes and Common Issues
The module fits a standard 288-pin DDR4 RDIMM slot and operates at the standard 1.2V. Installation is straightforward: align the notch, press firmly until the latches click, and confirm the module is seated evenly. The most common issue is mixing registered and unbuffered DIMMs or exceeding the platform's maximum rank-per-channel limit, which prevents the system from posting.
The Deciding Specification
The single specification that determines compatibility is the registered ECC RDIMM form factor combined with the 2Rx4 rank structure. Your motherboard and CPU memory controller must explicitly support registered ECC DDR4 at 2933MHz with this rank configuration; otherwise the module will not function.
