Dell PowerEdge R6615 Compatible Module

This NEMIX RAM module delivers 16GB of DDR5 registered ECC memory built for the Dell PowerEdge R6615 rack server. It operates at 4800MT/s with CL40 latency at 1.1V using a 288-pin RDIMM form factor. The single-rank 1Rx8 design uses major OEM chips from Samsung Micron or Hynix and ships without a heat spreader.

Upgrade From Slower DDR5 Or Smaller Capacity

Replacing slower DDR5 modules or lower-capacity sticks with this 16GB PC5-38400 unit adds bandwidth and ECC protection for virtualisation databases and high-throughput workloads. The jump is worthwhile when your R6615 chassis has free DIMM slots and the memory controller supports the 4800MT/s data rate at 1.10V. Registered buffering keeps signal integrity stable across fully populated channels.

Verify Slot Count And BIOS Revision First

Confirm the R6615 motherboard has an available 288-pin DDR5 RDIMM slot and that the system BIOS recognises 1Rx8 registered modules at 4800MT/s. Check the Dell memory population guide for maximum per-slot capacity and required slot-filling order. Ensure the operating voltage is set to 1.1V in firmware before installation.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the Dell PowerEdge R6615 memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the Dell PowerEdge R6615 memory slots for direct installation.

What is the correct seating procedure for the 1Rx8 registered module, and what step is often missed?

Align the notch, press firmly until both ejector clips click; the step often missed is verifying both clips are fully latched after insertion.

When should the 16GB ECC registered module be replaced in a Dell R6615?

Replace if system logs report uncorrectable ECC errors or if memory diagnostics fail during scheduled maintenance windows.
