Dell PowerEdge XE9680 Compatibility

This 64 GB DDR5 4800 ECC RDIMM is built for the Dell PowerEdge XE9680 server. It targets administrators who need registered, error-correcting memory for mission-critical workloads. The module runs at 1.1 V with CL40 latency. Buyers who require non-ECC or unbuffered DIMMs for consumer platforms should look elsewhere.

288-Pin RDIMM Build and 2Rx4 Organisation

The stick uses a standard 288-pin DDR5 RDIMM form factor without a heat spreader, relying on server chassis airflow for cooling. Its 2Rx4 rank layout and registered buffer reduce electrical load on the memory controller, supporting dense population in multi-socket Dell boards. Systems that cannot accept registered ECC modules will not post with this DIMM installed.

Single-Module Pack and Lifetime Replacement

The package contains one 64 GB module (part number MR38400-924K1) tested under load before shipment. NEMIX RAM backs the part with a lifetime replacement guarantee and US-based technical support staffed by IT professionals. No additional cables, brackets or software utilities are bundled with the memory.
