Server Memory Kit

This 256GB kit contains eight 32GB DDR4 3200 ECC RDIMM modules built for Dell PowerEdge R7525 rack servers. Registered buffering and error correction protect data integrity in mission-critical workloads. IT professionals specify this configuration to maximise the memory capacity of compatible Dell platforms.

DDR4 3200 Interface Limits

The PC4-25600 standard caps transfer rates at 3200 MT/s with a CL22 latency at 1.20V. Registered DIMMs add a clock cycle for address/command buffering, so throughput is bounded by the DDR4 JEDEC ceiling rather than the module itself. Systems that require faster memory must move to a newer generation.

2Rx4 Rank Organisation

Each 32GB module uses a dual-rank 2Rx4 layout, which determines how the memory controller interleaves accesses across banks. Servers with rank-per-channel limits or specific population rules will only accept this kit if the 2Rx4 configuration matches the platform's qualified vendor list. Buyers who need single-rank modules or a different rank count must choose another part.

Questions about this item

Should I choose the 256GB kit with eight 32GB modules or a different capacity for my Dell PowerEdge R7525?

The 256GB kit provides eight 32GB RDIMMs to fill eight slots, matching the R7525's memory architecture for balanced channel population.

What does the DDR4 3200 PC4-25600 rating deliver once installed in the server?

The modules run at 3200 MT/s with CL22 latency at 1.2V, providing the rated bandwidth when the platform operates memory at that speed.

How does the 288-pin ECC RDIMM interface affect compatibility and maximum capacity?

The 288-pin registered DIMM with ECC and 2Rx4 organisation is the required form factor for the R7525, allowing this 256GB kit to be installed.
