Dell PowerEdge R760xa memory kit

This 256GB kit contains eight 32GB DDR5 4800 RDIMM modules built for the Dell PowerEdge R760xa. Each module runs at 1.1V with CL40 latency and 2Rx8 organisation. ECC and registered buffering protect data integrity in continuous server workloads.

Suited for administrators expanding R760xa capacity

The kit matches the validated Dell specification, so installation follows the standard server procedure. Buyers who need a different capacity, speed or form factor should look at other options because this kit is fixed at 256GB, DDR5 4800 and 288-pin RDIMM.

Registered ECC RDIMM with 2Rx8 layout

The registered buffer and on-die ECC correct single-bit errors and reduce electrical load on the memory controller. This combination is the single specification that determines whether the modules will function in the target platform.
