Dell PowerEdge XR2 Compatible DDR4 RDIMM

This 8GB DDR4 2666 registered ECC module is built for Dell PowerEdge XR2 rack servers. It uses a 1Rx8 organisation, runs at 1.2V and carries a CL19 latency rating. The 288-pin RDIMM form factor fits the server's memory slots directly.

Suited for IT teams expanding XR2 capacity.

The registered ECC design targets Dell PowerEdge XR2 systems that require error-correcting registered memory. Workstations or desktops that accept only unbuffered non-ECC DIMMs cannot use this module. Buyers needing higher densities per slot should look at larger-capacity registered kits.

Verify slot count, maximum capacity

Check the XR2 service manual for the total number of DIMM slots, the maximum supported memory and any rank-per-channel limits before ordering. Confirm the server's BIOS revision supports 1Rx8 registered modules at the 2666 speed. Ensure the operating system can address the additional capacity.

Questions about this item

What server chassis must I already have to install this 288‑pin DDR4 2666 ECC RDIMM?

The module is validated for Dell PowerEdge XR2 rack servers and fits any system that accepts 288‑pin DDR4 RDIMMs at 2666 MT/s.

Can I mix this 1Rx8 CL19 1.20 V stick with existing 2Rx4 or 2Rx8 modules in the same channel?

Dell PowerEdge XR2 platforms allow mixed ranks per channel; populate identical ranks first, then add this 1Rx8 module following the server’s population guide.

How do I confirm the module runs at PC4‑21300 with ECC active after installation?

Enter the BIOS or iDRAC and verify the memory speed shows 2666 MT/s, voltage 1.20 V, CAS latency 19 and ECC status enabled.
