Capacity and form factor

This 1.5 TB kit contains twelve 128 GB DDR5 RDIMM modules in a 288-pin registered layout. It is built for servers that require maximum density per slot and full ECC protection.

Upgrade scope

The kit replaces partial or lower-capacity memory sets when the ASRock Rack TURIN2D24XGM/500W motherboard needs all slots populated at rated speed. The jump is worth it when workloads demand the full 1.5 TB address space without down-clocking.

Sustained operation

Registered buffering and on-die ECC keep every rank stable at 6400 MT/s and 1.1 V under continuous load. The 2Rx4 organization maintains signal integrity across all twelve modules during extended compute runs.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the memory slots on my ASRock Rack TURIN2D24XGM/500W motherboard?

Yes, the 12-module kit uses the 288-pin Registered DDR5 form factor that this board requires, not UDIMM or SODIMM, and it matches the DDR5-6400 speed the platform expects.

What population order should I follow when installing all 12 modules on the TURIN2D24XGM/500W?

Install the 128GB 2Rx4 RDIMMs in the exact slot sequence shown in the motherboard manual; skipping a slot or mixing ranks will prevent the system from recognising the full 1.5TB capacity.

When should I expect to replace a module in this 12x128GB DDR5-6400 ECC RDIMM kit?

ECC corrects single-bit errors automatically, but if the OS logs uncorrectable errors or the module fails POST, replace the affected stick; the kit carries a lifetime replacement warranty.
