128 GB DDR5 ECC RDIMM for ASRock Rack

This 128 GB DDR5 6400 RDIMM is built for servers that require registered ECC memory on the ASRock Rack TURIN2D16-2T/ROT platform. The 2Rx4 organization and CL52 timing match the board's memory controller expectations so the full capacity is recognized at rated speed. It targets administrators who need maximum density per slot in a validated configuration.

Registered 288-pin design with 1.1 V operation

The module uses a 288-pin registered form factor that buffers address and command signals, allowing every slot to be populated without overloading the memory controller. ECC circuitry corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. No heat spreader is fitted, so airflow across the PCB must be provided by the chassis.

Direct replacement for lower-capacity DDR5 RDIMMs

Installing this kit replaces smaller DDR5 registered DIMMs to reach the higher per-slot density the motherboard supports, avoiding the need for additional slots or slower speeds. The jump is worth it when workloads demand more memory bandwidth and capacity within the same validated population rules. Buyers who need unbuffered UDIMMs or SODIMMs cannot use this module.

Questions about this item

What DDR5 speed and CAS latency does this 128GB RDIMM run at?

This module operates at DDR5 6400 (PC5-51200) with a CAS latency of CL52, so the memory controller sees 6400 MT/s at the rated timing.

Which physical slot and form factor does this 288-pin RDIMM require on the ASRock Rack TURIN2D16-2T/ROT?

It needs a standard 288-pin DDR5 RDIMM slot; the board must accept registered DIMMs, not UDIMM or SODIMM, and the 2Rx4 rank layout must match the motherboard's population rules.

How do I install this registered ECC module and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that all 128GB are detected at 6400 MT/s with ECC active — the step many skip is confirming the population order in the motherboard manual before seating the DIMM.
