256GB DDR5 ECC RDIMM Kit

This 256GB kit contains two 128GB registered DDR5 modules built for server and workstation platforms that require error-correcting memory. It targets administrators upgrading an ASRock Rack W890D8-2L2T motherboard or any system validated for this exact part number.

Registered 4Rx4 Architecture at CL52

Each module uses a 4Rx4 organisation and runs at CL52 latency with a 1.10V operating voltage. The registered buffer and ECC functionality are mandatory for the target platform; systems expecting unbuffered or non-ECC DIMMs will not accept this kit.

256GB Total Capacity for Dense Workloads

The paired 128GB DIMMs deliver 256GB of addressable memory, supporting large virtualisation hosts, in-memory databases and heavy compilation jobs. Capacity ends at 256GB; configurations requiring more memory must populate additional slots with matching registered ECC modules.

Perguntas sobre este artigo

What does the CL52 latency mean for real-world server responsiveness?

CL52 is the CAS latency at 6400 MT/s; lower cycles mean faster column access, so the registered ECC modules keep transactional workloads moving with minimal delay.

What does the PC5-51200 designation tell me about the memory interface?

PC5-51200 identifies DDR5-6400 operation; the registered DIMM interface caps at that transfer rate and the motherboard must support the same speed to realise it.

Will the 288-pin RDIMM kit fit the ASRock Rack W890D8-2L2T motherboard slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the board's memory slots and the kit is validated for that specific model.
