RIMLANCE
A 64GB DDR4 2400MHz registered ECC RDIMM with CL17 latency and 4Rx4 rank for server workloads
This single 64GB DDR4 module runs at 2400MHz with CL17 latency and registered ECC for data integrity. It uses a 4Rx4 organisation on a 288-pin form factor at 1.2V. The PC4-19200 rating supports high-throughput server workloads. Major-brand DRAM chips underpin the rated stability.
This module fits systems that require registered DDR4 ECC memory with a 4Rx4 layout. It is not for desktops or laptops that accept only unbuffered non-ECC DIMMs. Builders whose platforms cannot address 64GB per slot or that demand a different rank configuration should look elsewhere. Compatibility must be confirmed before purchase.
The 64GB density determines how many slots are needed to reach a target system memory total. Each DIMM delivers the full capacity in a single 288-pin registered package. Verify the platform's maximum supported capacity per slot and total population limit. This single figure drives the upgrade plan.

Align the notch with the slot key, press down firmly until both retention clips click shut, then verify the module is fully seated; the step often missed is checking both clips are locked.
No routine maintenance is required; replacement is only needed if a memory error appears or capacity must be increased beyond 64GB.
The DDR4 2400MHz PC4-19200 bandwidth ceiling is reached before latency or thermal limits become a bottleneck.
