Exact-Match Server Upgrade

This 32GB DDR5-6400 Registered ECC RDIMM is built for the ASRock Rack GNRAP2D24G-2L+ motherboard. It delivers the precise 1Rx4 rank, 1.1V voltage, and CL52 timing the memory controller expects for full-capacity recognition at rated speed. The 288-pin RDIMM form factor matches the board's registered-DIMM requirement exactly. No UDIMM or SODIMM alternative will fit this platform.

Verify Configuration First

Consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase. Server memory support varies by model, and the board's population rules must be followed for stable operation. Ensure the platform accepts Registered ECC modules at DDR5-6400 with a 1.1V operating voltage. Only the documented configuration guarantees compatibility.

For Enterprise Stability Needs

This module suits administrators who need Registered ECC architecture to offload the memory controller and correct single-bit errors on the fly, preventing silent data corruption in production environments. Buyers who need unbuffered UDIMMs, non-ECC memory, or SODIMM form factors should look elsewhere. Systems requiring different speeds, voltages, or rank configurations cannot use this kit.

Questions about this item

Does the 32 GB DDR5 6400 kit include any extra cables, heat spreaders or mounting hardware, or is it just the registered DIMM?

The package contains only the 32 GB DDR5 6400 CL52 1Rx4 registered ECC RDIMM. No heat spreader, cables or additional hardware are supplied.

How do I decide between this 32 GB module and a larger or smaller capacity for the ASRock Rack GNRAP2D24G-2L+?

Check the motherboard manual for maximum supported capacity per slot and total system limit, then choose the module size that matches your planned population order.

What does the 6400 MT/s rating actually deliver once the RDIMM is installed in the server?

The module runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1 V, giving the full rated bandwidth when the board's memory controller is populated per its rules.
