Dell PowerEdge XR8000-series DDR5 RDIMM kit

This NEMIX RAM kit supplies 256GB of DDR5 memory across eight 32GB registered DIMMs. Each module runs at 4800MT/s with CL40 latency at 1.1V and includes on-die ECC. The 288-pin RDIMM form factor is built for Dell PowerEdge XR8000, XR8610t and XR8620t rack servers.

IT teams scaling Dell rack servers

The kit suits administrators who need a validated 256GB DDR5 upgrade for the listed PowerEdge models and want registered ECC modules tested under load. Buyers requiring non-registered UDIMMs, different densities, speeds above 4800MT/s or compatibility with other server platforms should look elsewhere.

256GB eight-module registered ECC capacity

The decisive specification is the 256GB (8×32GB) DDR5 4800 RDIMM configuration with 2Rx8 organisation and on-die ECC. Confirm the server’s memory population rules and maximum supported capacity before purchase.

Questions about this item

What DDR5 speed and data rate does this 256GB kit run at?

The kit operates at DDR5 4800 with a PC5-38400 data rate and CL40 latency at 1.1V.

What physical slot and form factor do these modules require?

Each 32GB module is a 288-pin DDR5 RDIMM with a 2Rx8 organisation and no heat spreader.

How are the eight RDIMMs installed in a Dell PowerEdge XR8610t or XR8620t and what step is often missed?

Populate all eight slots following the server's channel order, then enable ECC and registered mode in BIOS so the 2Rx8 ranks are recognised.
