Exact-fit server kit

This NEMIX RAM kit delivers 256GB of DDR5 memory as two 128GB registered DIMMs. It is built for the ASRock Rack TURIN2D16-2T/ROT motherboard where the memory controller expects registered ECC modules at the rated speed. The 2Rx4 organisation and CL52 timing match the board's native requirements so the full capacity is recognised at DDR5-6400.

Verify board population rules

Server memory support varies by model and BIOS revision. Consult the motherboard manual for the approved DIMM population order, maximum capacity per channel and any required firmware updates before ordering. The kit uses the 288-pin registered form factor this board requires, not unbuffered or SO-DIMM alternatives.

Enterprise-grade construction

Registered architecture buffers the command bus so every slot runs fully populated without overloading the memory controller. ECC corrects single-bit errors on the fly to prevent silent data corruption in production workloads. Modules operate at 1.1V and carry no heat spreader, relying on the server chassis airflow for cooling.

Questions about this item

What comes inside the 256GB kit and do I need any extra parts to install it in the ASRock Rack TURIN2D16-2T/ROT?

The kit contains two 128GB DDR5 6400 CL52 1.1V ECC Registered RDIMM modules. No additional components are required for installation on the compatible motherboard.

Should I choose the 2 x 128GB 2Rx4 kit or a different capacity for the TURIN2D16-2T/ROT?

The 2 x 128GB 2Rx4 Registered ECC kit matches the motherboard's DDR5 6400 specification and population rules. Other capacities or ranks may not be supported at full speed.

What does the DDR5 6400 PC5-51200 rating mean once the modules are running in the server?

The modules operate at 6400 MT/s with CL52 latency at 1.1V, delivering the rated bandwidth and error-correcting stability the motherboard expects when fully populated.
