512GB DDR5 6400 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 6400 Registered ECC RDIMMs built for the ASRock Rack GNR2D16-2T motherboard. The 2Rx4 organization and 1.1V operating voltage match the board's memory-controller requirements so every slot is recognized at full capacity. It targets server administrators who need maximum registered memory density without mixing module types.

Registered DDR5 limits at full population

Registered (buffered) architecture offloads the memory controller so all four slots can run fully populated at the rated 6400 MT/s speed. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. The 288-pin RDIMM form factor is mandatory for this platform; UDIMM or SODIMM modules will not fit or function.

Upgrade from smaller or mixed-capacity kits

Replacing partial or mixed-capacity kits with this matched 4x128GB set eliminates population-rule conflicts and ensures the memory controller trains at the rated CL52 latency. The jump is worth it when the workload demands the full 512GB registered capacity and the motherboard manual confirms support for this exact rank and voltage configuration. Buyers who need non-ECC memory or consumer UDIMM form factors should look elsewhere.

商品問答

Should I choose the 512GB kit or a smaller capacity for the ASRock Rack GNR2D16-2T?

The 512GB kit provides four 128GB modules that fill all slots for maximum capacity and ranked performance on the ASRock Rack GNR2D16-2T.

What does DDR5 6400 CL52 mean for real-world server throughput?

DDR5 6400 transfers data at 6400 MT/s while CL52 sets the latency window; together they deliver the rated bandwidth the memory controller expects when all four slots are populated.

How does the 288-pin RDIMM interface and registered design affect compatibility?

The 288-pin registered DDR5 RDIMM format is the exact physical and electrical interface the ASRock Rack GNR2D16-2T requires; the registered buffer lets every slot run fully populated at 6400 MT/s.
