OWC 128GB DDR4 ECC Registered RDIMM

This single 128GB DDR4 3200 module uses a 288-pin ECC registered design with 8Rx4 organisation and CL22 latency. It is built for ASUS GPU servers including the ESC N4A-E11, ESC4000A-E11, ESC4000-E10, ESC4000-E10S and ESC8000A-E11. The module operates at 1.2V and meets JEDEC PC4-25600 specifications. It targets administrators expanding memory capacity in compatible rackmount or workstation chassis.

Verify registered ECC support and rank limits

Before ordering, confirm the server platform accepts registered ECC RDIMMs and supports 8Rx4 modules at the desired population. The memory cannot be mixed with unbuffered or load-reduced ECC DIMMs. Check the system documentation for maximum supported capacity per slot and total channel population rules. Ensure the BIOS revision in use recognises 128GB density modules at 3200 MT/s or at the lower supported speeds of 2133, 2400, 2666 or 2933 MT/s.

Sustained load behaviour in multi-DIMM

Under continuous workloads the registered buffer reduces electrical loading on the memory controller, helping maintain signal integrity across fully populated channels. ECC correction handles single-bit errors without interrupting compute tasks running on the supported ASUS GPU servers. The module runs at the standard 1.2V DDR4 voltage, so thermal output remains consistent with other JEDEC-compliant RDIMMs of the same speed grade.

Questions about this item

Does the 128GB DDR4 3200 CL22 8Rx4 288-pin ECC Registered RDIMM come as a single module or do I need to buy multiple sticks?

The OWC upgrade consists of a single 128GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Registered DIMM. No extra modules are required for this capacity.

Should I choose this 128GB 8Rx4 module or a lower-capacity alternative for my ASUS GPU Server ESC N4A-E11?

This 128GB 8Rx4 module maximises capacity per slot. Choose it when the server has limited DIMM slots and you need the highest density per channel.

What does the 3200 PC4-25600 rating mean once the module is installed in an ASUS ESC4000A-E11?

The module runs at DDR4 3200 with CL22 latency at 1.2V. It also operates at 2133MHz, 2400MHz, 2666MHz and 2933MHz if the platform requires a lower speed.
