128GB DDR5-4800 ECC RDIMM Kit

This 128GB kit contains four 32GB DDR5-4800 Registered ECC RDIMMs built for the ASRock Rack GENOA2D24G-2L+ motherboard. The 1Rx4 modules run at 1.1V with CL40 latency, matching the board's memory-controller expectations for full-capacity recognition at rated speed. It is intended for administrators upgrading that specific server platform.

Verify Manual Population Rules

Server and motherboard memory support varies by model, so consult the system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before ordering. The 288-pin Registered form factor is required; UDIMM or SODIMM modules will not fit or function in this board.

Registered ECC Under Sustained Load

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity during continuous operation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots before they reach production workloads.

Questions about this item

What comes in the 128GB kit and do I need anything else to install it?

The kit includes four 32GB DDR5 4800 CL40 1Rx4 ECC Registered RDIMM modules. No extra parts are required; the 288-pin DIMMs install directly into the motherboard memory slots.

How do I decide between this 128GB kit and a smaller capacity for the ASRock Rack GENOA2D24G-2L+?

Choose the 128GB kit when your workload needs the full capacity across four slots. Check the motherboard manual for supported capacities and population rules before selecting a smaller kit.

What does the DDR5 4800 CL40 rating mean once the modules are running in the server?

The modules operate at 4800 MT/s with CAS latency 40 at 1.1V. Registered buffering and ECC keep every slot stable at full speed while correcting single-bit errors on the fly.
