Server-specific 64GB DDR4 module

This 64GB DDR4 ECC registered DIMM is built for Dell PowerEdge R6515, R6525, R750, R750xa and R750xs servers. It targets administrators upgrading or repairing those platforms with validated, JEDEC-compliant memory. The module will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs.

DDR4 3200 registered limits

The DDR4 3200 interface caps transfer rate at PC4-25600 while the registered design adds a clock cycle for address and command buffering. ECC operation requires platform support for error correction, which these PowerEdge models provide. Mixing with unbuffered memory or installing in unsupported systems will prevent boot or disable ECC.

64GB capacity and headroom

A single 64GB 2Rx4 module fills one 288-pin slot and suits workloads that need large memory footprints such as virtualisation or in-memory databases. Capacity headroom ends when all authorised slots are populated or the platform maximum is reached. Beyond that point, additional modules cannot be added without a server change.

Questions about this item

Should I pick a single 64GB module or add multiple sticks for my Dell PowerEdge R750?

This listing is for one 64GB DDR4 3200MHz CL22 ECC Registered RDIMM. OWC recommends matching capacity, speed and manufacturer across all slots for optimal performance.

What does the 3200MHz rating deliver inside a PowerEdge R6525?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V. Actual throughput depends on the server's memory controller and how many DIMMs are populated per channel.

Will the 288-pin RDIMM interface work with my R750xa's memory slots?

Yes, the 288-pin DDR4 ECC Registered RDIMM form factor matches the slots in the R750xa, R750xs, R750, R6515 and R6525. It cannot be mixed with unbuffered memory.
