Capacity and form factor

This kit provides 512 GB of DDR5 server memory across four 128 GB registered RDIMM modules. It is built for the ASRock Rack GNRAPD12DNO motherboard and suits administrators who need maximum supported capacity with ECC protection.

Installation and fit

The 288-pin registered DIMMs install in the standard DDR5 slots of the target board; registered architecture lets all four slots run fully populated at rated speed. Verify the motherboard manual for approved population order and any BIOS settings before seating the modules.

Speed, latency and voltage

Rated DDR5 6400 (PC5-51200) with CL52 latency at 1.10 V, the kit matches the exact timing and voltage the memory controller expects for stable operation at full capacity.

Perguntas sobre este artigo

How can I verify the 512GB kit is running at DDR5 6400 CL52 after installation?

Check the BIOS memory information screen or a tool such as CPU-Z; it should report 6400 MT/s, CAS latency 52, 1.10 V and all four 128 GB modules recognised as a 512 GB Registered ECC 2Rx4 configuration.

What does the package contain and is anything else required to use it?

The box holds the 512 GB kit as four 128 GB 288-pin DDR5 RDIMMs; no extra parts are needed if your ASRock Rack GNRAPD12DNO motherboard has four free RDIMM slots and supports the stated speed and voltage.

Should I choose this 512 GB (4 × 128 GB) kit or a different capacity for the GNRAPD12DNO?

Select this kit when the board's qualified-vendor list approves 128 GB 2Rx4 RDIMMs and you need the maximum 512 GB across four slots; choose a smaller kit only if your manual limits per-slot capacity or total memory.
