Compatibility

This 64GB DDR5 module is built for the ASUS RS700A-E12-RS12U 1U dual-processor server. It delivers registered ECC operation at 4800MT/s with a CL40 latency profile. The 2Rx4 organisation and 1.10V voltage match the platform's qualified memory list. IT teams can install it as a single 64GB upgrade without mixing ranks.

Thermals

The module runs at the standard DDR5 1.10V level and carries no heat spreader. In a 1U chassis the registered buffer and ECC logic add minimal overhead to the DIMM's power draw. Airflow from the server's front-to-rear fans is sufficient to keep the DRAM within specification during normal multi-threaded workloads.

Sustained load

Under continuous database or virtualization traffic the registered interface maintains signal integrity across both ranks. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 4800MT/s data rate and CL40 timing remain stable without throttling when all DIMM slots are populated.

Questions about this item

How do I install this 288-Pin DDR5 RDIMM into the ASUS RS700A-E12-RS12U server, and which step is commonly missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 64GB module registers at 4800MT/s with ECC active; the step often missed is confirming the registered ECC mode is enabled in firmware.

What maintenance or replacement will this 1.10V 2Rx4 ECC module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.10V, so keep server airflow clean and monitor ECC corrected-error counters — replace the DIMM only if uncorrectable errors appear or capacity must increase beyond 64GB.

What limit appears first when this CL40 registered memory runs sustained workloads?

The CAS latency of CL40 at 4800MT/s sets the timing ceiling; under continuous load the memory controller will hit latency-bound throughput before thermal or voltage limits become a factor.
