64 GB DDR4-3200 ECC Registered DIMM

This 64 GB DDR4-3200 module targets servers and workstations that require error-correcting registered memory. The dual-rank 2Rx4 organisation and CL22 latency suit high-density configurations. It operates at 1.20 V and conforms to the PC4-25600 standard. Systems without ECC registered support cannot use this module.

288-pin installation and seating

The 288-pin DIMM fits standard DDR4 slots and requires no heat spreader removal. Firm even pressure until the retention clips click avoids the most common fault: a partially seated module that causes boot failures or memory errors. Verify that the platform enables registered memory in the BIOS before installation.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors that accumulate under long-running workloads. The CL22 timing and 3200 MHz speed deliver stable throughput without thermal throttling, as the module lacks a heat spreader and relies on chassis airflow.

Questions about this item

How can I verify the module is running at 3200 MHz with CL22 timings after installation?

Check the BIOS or UEFI memory information screen; it should report 3200 MHz speed and 22-22-22 latency for this DDR4-3200/PC4-25600 registered ECC DIMM.

What comes in the box and do I need any extra brackets or cables?

The package contains the single 64 GB 288-pin DDR4 RDIMM only; no heat spreader, brackets, cables or additional hardware are included.

Which capacity and rank option should I choose for a dual-CPU server board with eight slots per processor?

This module provides 64 GB in a dual-rank 2Rx4 configuration; populate slots according to the motherboard's memory population guide for optimal channel balance.
