128GB DDR5 ECC RDIMM Server Memory

This 128GB DDR5 ECC RDIMM module is built for ASRock TRX50 WS workstation motherboards that require registered memory. It delivers 128GB capacity in a single 288-pin DIMM running at 5600MT/s with CL46 latency. The module operates at 1.1V and uses a 4Rx4 organisation with major OEM DRAM chips. It targets IT professionals who need validated, high-density registered ECC memory for mission-critical server and workstation deployments.

Suited for registered ECC platforms only

This module suits builders populating an ASRock TRX50 WS board or other platforms that explicitly require DDR5 registered ECC RDIMMs with 4Rx4 ranking. It is not for consumer desktop boards that accept only unbuffered non-ECC UDIMMs. It is also not for systems limited to lower-density 1Rx8 or 2Rx8 modules, or for laptops and small-form-factor devices that use SO-DIMM form factors. Buyers needing unbuffered memory or different rank configurations should look at other product lines.

4Rx4 rank decides platform compatibility

The single specification that determines fit is the 4Rx4 rank organisation combined with registered ECC signalling. Only motherboards qualified for 4Rx4 DDR5 RDIMMs at 5600MT/s can use this module. Verify the platform memory-qualified vendor list before purchase; a mismatch in rank or registered versus unbuffered type will prevent boot or reduce usable capacity. The 1.1V operating voltage and CL46 timing are secondary to the rank and buffer requirement.

Questions about this item

What speed does the DDR5 5600 interface cap at in practice?

The module runs at DDR5 5600 (PC5-44800) with a CAS latency of CL46.

What physical slot and clearance does this 288-pin RDIMM need to fit?

It requires a standard 288-pin DDR5 RDIMM slot; no heat spreader is fitted so height clearance is minimal.

How is this single 128 GB module installed, and what step is often missed?

Insert the module into the correct DDR5 RDIMM slot per the motherboard manual, ensuring the registration notch aligns, and verify the BIOS recognises the full 128 GB capacity.
