256GB DDR5 ECC RDIMM kit

This kit supplies 256GB of DDR5 ECC registered memory in two 128GB modules for the ASRock WRX90 WS EVO motherboard. It targets workstations and servers that require error correction and registered signalling for stability under sustained load.

DDR5 4800 registered limits

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V and a 4Rx4 organisation. Registered DIMMs add a clock cycle of buffering, so maximum usable speed and total capacity depend on the motherboard memory controller and qualified vendor list.

Check motherboard QVL and CPU support

Verify that the WRX90 WS EVO qualified vendor list includes this part number and that the installed processor supports 256GB of registered ECC memory at the rated speed. Confirm the board has two free 288-pin DDR5 RDIMM slots and that the BIOS is updated to the version recommended for high-capacity registered modules.

Perguntas sobre este artigo

Should I pick the 256 GB kit or a smaller kit for my ASRock WRX90 WS EVO?

The kit supplies 256 GB as two 128 GB modules. Choose it when your workload needs that capacity and the board has enough DDR5 RDIMM slots.

What does DDR5 4800 mean once the modules are installed?

The memory runs at 4800 MT/s with CL40 latency at 1.10 V, delivering PC5-38400 bandwidth for registered ECC workloads.

How does the 288-pin RDIMM interface limit what I can do?

The 288-pin DDR5 RDIMM form factor fits only DDR5 RDIMM slots and the registered design requires a motherboard that supports registered ECC memory.
