128 GB DDR5 ECC RDIMM Kit

This 128 GB kit contains two 64 GB DDR5 4800 registered DIMMs built for the ASRock TRX50 WS workstation motherboard. ECC and registered buffering protect data integrity in professional workloads. The modules run at 1.1 V with a CL40 latency profile. IT professionals and workstation builders who need maximum capacity with error correction will use this memory.

Sustained Load Stability

Each module uses a 2Rx4 organisation with major OEM Samsung, Micron or Hynix chips validated under extended stress testing. Registered signalling reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors in real time without halting the system. The 1.1 V operating voltage helps maintain thermal headroom during long compute sessions.

Capacity Upgrade Path

The kit replaces lower-density DDR5 RDIMM populations to reach 128 GB in two slots, leaving room for further expansion on the platform. Builders moving from non-ECC or unbuffered memory gain registered buffering and error correction in a single step. The jump is worth it when workloads demand both maximum capacity per module and data integrity guarantees.

Questions about this item

How much power does the 1.10V DDR5 kit draw when the workstation runs all day?

Each module operates at 1.10V, the standard DDR5 voltage, so total power scales with the 128GB capacity and your CPU workload.

What motherboard slot and firmware does the ASRock TRX50 WS need for these 288-pin RDIMMs?

The board must provide DDR5 RDIMM slots and a BIOS that supports registered ECC memory at 4800 MT/s.

Will these 2Rx4 CL40 modules run at 4800 MT/s alongside slower DDR5 ECC RDIMMs I already own?

The memory controller will downclock all installed DIMMs to the lowest common speed and tightest timings.
