Size 512GB 4X128GB

  • 512 GB total capacity from four 128 GB modules for maximum server density
  • DDR5 5600 speed with CL46 latency delivers rated throughput for the ASRock Rack platform
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operating voltage matches the board's memory-controller specification exactly
  • 288-pin RDIMM form factor ensures physical and electrical compatibility with the target motherboard

Server-grade capacity and compatibility

This 512GB kit delivers four 128GB DDR5 RDIMM modules tuned to 5600MHz with CL46 timing and 1.1V operation. It is built specifically for the ASRock Rack TURIN2D48G-2L+/500W motherboard, matching the exact rank, voltage and timing the platform expects. The registered ECC design targets enterprise workloads that demand maximum density and error correction.

Registered ECC build and 288-pin form factor

Each module uses a 2Rx4 registered architecture that buffers address and command signals, allowing all slots to run fully populated at rated speed. ECC circuitry detects and corrects single-bit errors on the fly, reducing silent data corruption and unplanned reboots. The 288-pin RDIMM form factor fits only boards wired for registered DDR5; it will not work in UDIMM or SODIMM slots.

DDR5-5600 bandwidth and population rules

The PC5-44800 interface provides the throughput ceiling for this kit; actual bandwidth depends on the memory controller and channel configuration of the host system. Full-capacity operation requires strict adherence to the motherboard's approved DIMM population order and supported capacity limits. Consult the system manual before installation to confirm slot sequence and any BIOS settings needed for stable operation.

Questions about this item

What DDR5 speed and CAS latency does this 512GB kit run at?

The kit operates at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, matching the ASRock Rack TURIN2D48G-2L+/500W memory controller spec for full rated speed.

What physical slot and form factor do these modules need?

Each 128GB module is a 288-pin DDR5 RDIMM; the board requires registered DIMMs, not UDIMM or SODIMM, so they only fit the server's 288-pin RDIMM slots.

How do I install the four modules in the correct population order?

Consult the ASRock Rack TURIN2D48G-2L+/500W manual for the approved DIMM population sequence; installing in the wrong slot order is the common mistake that prevents full 512GB recognition.
