Dell Precision 5860 Compatible DDR5 RDIMM

This 128GB registered DDR5 module is built for the Dell Precision 5860 tower workstation. It targets IT professionals and enterprises that need ECC-protected memory for mission-critical workloads such as virtualization, rendering or large-scale data analysis.

DDR5 4800 Registered ECC Limits

The module runs at 4800 MT/s with CL40 latency at 1.10V, conforming to the PC5-38400 standard. Registered buffering and 4Rx4 organisation add command-address stability for high-capacity configurations, but the registered design prevents use in consumer boards that accept only unbuffered DIMMs.

288-Pin RDIMM Installation Notes

Installation follows the standard 288-pin DDR5 keying; align the notch and press until the latches click. Common issues include mixing registered and unbuffered modules, populating slots in the wrong order per the Dell service manual, or leaving a latch unseated, which causes boot failure.

Questions about this item

Should I pick the single 128 GB module or combine smaller sticks to reach the same total?

The module is sold as one 128 GB stick, so you install a single DIMM to add that capacity.

What does the 4800 MT/s rating deliver inside a Dell Precision 5860 workstation?

The memory runs at DDR5 4800 with CL40 latency at 1.1 V, matching the platform's native speed for registered ECC DIMMs.

How does the 288-pin RDIMM interface limit the maximum bandwidth I can use?

The registered 288-pin DDR5 form factor supports PC5-38400 throughput, which is the peak transfer rate the slot and module combination can sustain.
