256GB DDR5 Server Kit

This 256GB kit contains sixteen 16GB DDR5 4800 RDIMM modules built for Dell PowerEdge R760xa rack servers. Registered ECC operation and 1Rx8 organisation provide the error correction and signal integrity required by mission-critical workloads. IT teams specifying memory for virtualisation hosts or database clusters will find the capacity and reliability profile matched to those demands.

Registered ECC Build Quality

Each module uses major OEM DRAM from Samsung, Micron or Hynix and runs at 1.10V without a heat spreader. The 288-pin registered interface buffers address and command signals, reducing electrical load on the server memory controller. Daily operation benefits from rigorous stress testing under load, ensuring stability in densely populated DIMM slots across the platform.

Upgrade From Lower Capacity DDR5

The kit replaces smaller DDR5 RDIMM sets when 256GB total capacity is needed for larger VM counts or in-memory datasets. The jump is worth it when current memory pressure forces paging or limits container density on the R760xa. Buyers who need more than sixteen slots or a different form factor cannot use this configuration.

Questions about this item

What does the DDR5 4800 PC5-38400 rating mean for real-world bandwidth?

The kit runs at 4800 MT/s, delivering a peak transfer rate of PC5-38400, which is the maximum throughput supported by the DDR5 4800 standard for registered DIMMs.

Will these 288-pin RDIMMs fit in the Dell PowerEdge R760xa memory slots?

Yes, the 288-pin registered DIMM form factor matches the R760xa DDR5 slots; the kit contains sixteen 16 GB modules to populate the server's memory channels.

How do I install the sixteen 1Rx8 modules, and what step is often missed?

Power down the R760xa, open the chassis, align each module's notch with the slot key, press firmly until the ejectors click, then verify in BIOS that all 256 GB are detected at 4800 MT/s with ECC active.
