  • ECCYes

Capacity 16GB

  • ECC registered design protects data integrity in Dell Precision 5860 and 7960 workstations
  • 16 GB DDR5 4800 CL40 module boosts multitasking capacity for heavy workloads
  • 1 V operation reduces power draw while maintaining server-grade stability
  • Single-rank 1Rx8 layout simplifies population rules across compatible Dell Precision towers and rack
  • JEDEC-compliant 288-pin RDIMM ensures reliable drop-in upgrade for AC239377 SNP1V1N1C/16G replacement

Targeted Workstation Memory

This 16 GB DDR5 4800 CL40 registered ECC RDIMM is built for Dell Precision 5860 and 7960 series towers and the 7960 rack model. It delivers 16 GB of single-rank error-correcting memory at 1.1 V for systems that require registered modules.

Upgrade Path and Compatibility

The module replaces Dell part numbers AC239377 and SNP1V1N1C/16G in the listed Precision workstations. It cannot be mixed with unbuffered or load-reduced ECC DIMMs, so a full matched set is required when populating multiple slots.

Build Integration

The 288-pin form factor fits the registered DIMM slots on the supported Precision platforms without a heat spreader. It frees standard desktop memory slots for other builds while providing server-grade reliability for workstation workloads.

Perguntas sobre este artigo

Will the 288-pin DDR5 RDIMM fit the memory slots in a Dell Precision 5860 or 7960 tower?

Yes — the module is a 288-pin DDR5 ECC Registered DIMM built to JEDEC specifications, which matches the slot and electrical requirements of the listed Precision 5860 and 7960 workstations.

What is the common installation mistake with this ECC Registered memory?

Mixing it with unbuffered or ECC Load Reduced DIMMs — the manufacturer states this registered module cannot be combined with either type, so all slots must use matching registered ECC memory.

Does the 16 GB module need any future maintenance such as firmware updates or battery replacement?

No — DDR5 RDIMMs have no onboard firmware, battery or moving parts; the only later action would be adding more identical modules if the workload grows beyond 16 GB.
