Capacity 64GB

  • 64 GB capacity handles heavy server workloads
  • ECC registered design protects data integrity in critical systems
  • DDR4 2933 MHz CL21 delivers responsive throughput
  • 2 V operation reduces power draw per module
  • Validated for Supermicro X11DAC X11DAi-N X11DDW-L X11DDW-NT X11DGO-T

Target Server Platforms

This 64GB DDR4 ECC Registered RDIMM is designed for Supermicro motherboards X11DAC, X11DAi-N, X11DDW-L, X11DDW-NT and X11DGO-T. It serves administrators expanding memory in compatible workstation, server or NAS systems that require registered error-correcting modules.

Physical Build and Daily Use

The module uses a standard 288-pin DDR4 form factor without a heat spreader, operating at 1.2V with a 2Rx4 rank configuration. Its registered buffer adds electrical load on the memory controller, so it must be installed in platforms designed for registered DIMMs and cannot be mixed with unbuffered memory.

Pre-Installation Checks

Verify that your motherboard is one of the five listed Supermicro models and that the BIOS supports DDR4 2933MHz operation with CL21 latency. The module is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds, but it will not function in standard desktop computers or any system requiring unbuffered non-ECC memory.

Pluspunten

Vragen over dit artikel

What DDR4 speed and CAS latency does this module run at?

The module is rated for DDR4 2933 MT/s with a CL21 latency, corresponding to the PC4-23400 standard.

What physical slot and form factor does this 64 GB RDIMM require?

It uses a 288-pin DDR4 DIMM form factor and must be installed in a server or workstation motherboard that supports registered ECC memory.

How is this memory installed and what common mistake should be avoided?

Power down the system, align the notch with the slot key, and press firmly until the retention clips lock. Do not mix this registered ECC module with unbuffered memory.
