NEMIX RAM DDR5 5600MHz ECC Registered RDIMM 256GB (2x128GB) CL46 1.1V 2Rx4 memory upgrade

Exact-match DDR5-5600 ECC kit for ASRock Rack

This 256GB kit provides two 128GB registered DIMMs built to the DDR5-5600 (PC5-44800) standard with CL46 timing and 1.1V operation. The 2Rx4 organization and ECC function match the memory controller expectations of the ASRock Rack TURIND24QM3-2L2T/500W motherboard so the system recognizes full capacity at rated speed. It is intended for administrators who need maximum registered capacity in that specific platform. Builders using consumer boards, unbuffered slots, or a different DDR generation cannot use these modules.

Upgrading from lower-capacity RDIMMs

Replacing smaller registered DIMMs or a mixed-rank configuration with this matched 2x128GB kit lets the board run every slot at the full 5600MT/s data rate without downclocking. The jump is worth it when the workload demands the full 256GB address space and the motherboard's qualified-vendor list includes this exact part number. If the system manual limits total capacity per channel or requires a specific population order that this kit does not satisfy, the upgrade will not deliver the expected capacity.

Registered DDR5 interface limits

The 288-pin registered DDR5 interface buffers command and address signals so the memory controller can drive a full complement of slots at 5600MT/s, but the board's own trace routing and BIOS microcode still define the maximum reliable frequency and supported rank-per-channel count. ECC corrects single-bit errors and detects double-bit errors, yet it cannot protect against multi-bit failures or controller-level faults. The 1.1V operating voltage is fixed by the DDR5 standard for this speed grade; no higher or lower voltage option exists on these modules.
