Dell R860 server memory kit

This NEMIX RAM kit supplies 128GB of DDR5 ECC registered memory across eight 16GB modules. It is built for administrators upgrading Dell PowerEdge R860 rack servers that require registered DIMMs with error correction. The modules run at 4800 MT/s with a CL40 latency at 1.10V.

Replaces slower or smaller DDR5 RDIMMs

The jump is worth it when the R860 chassis has empty slots or is populated with lower-capacity sticks that limit virtual-machine density. Adding this 8x16GB kit fills a full bank with matched modules so the memory controller can operate in its optimal rank configuration.

Sustained load behaviour

Each module uses major OEM Samsung, Micron or Hynix chips validated under extended stress testing. Registered buffering and on-die ECC keep signal integrity stable during long compute runs, while the 1.10V operating point limits thermal drift across all eight DIMMs.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Dell PowerEdge R860 memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the Dell PowerEdge R860 DIMM slots exactly. The kit contains eight 16 GB modules for a total of 128 GB.

What is the correct installation sequence for the eight 1Rx8 modules in the R860?

Populate the memory channels evenly across all processors following the Dell R860 memory population guide; the common mistake is leaving a channel unbalanced which reduces bandwidth.

How do I know when a registered ECC module in this kit needs replacement?

The system logs correctable ECC errors; when the error count for any 1Rx8 module exceeds the platform threshold the module should be replaced to maintain data integrity.
