Server-grade DDR5 ECC kit

This 512 GB kit contains four 128 GB DDR5 4800 CL40 4Rx4 registered ECC RDIMMs built for Lenovo ThinkSystem SD650 V3, SD650-I V3, SD665 V3, SD665-N V3 and SR630 V3 servers. It delivers JEDEC-standard error-correcting memory for workloads that demand data integrity and high capacity.

Compatibility checklist

Verify that your system is one of the listed ThinkSystem models and that its memory slots accept 288-pin registered DDR5 RDIMMs running at 1.1 V. The modules are not compatible with standard desktop computers and must not be mixed with unbuffered or load-reduced ECC memory.

What the kit provides

Four matched 128 GB modules arrive ready to install, letting you populate four slots in a single step and reach the full 512 GB capacity without sourcing individual sticks. The registered design and on-die ECC maintain signal integrity across all channels for stable server operation.

Preguntas sobre este artículo

Does the 512GB kit ship as four 128GB modules or do I need to buy extra sticks?

The kit contains four 128GB DDR5 4800 CL40 4Rx4 registered ECC RDIMMs, giving 512GB total with no additional modules required.

Should I pick this 512GB 4800 CL40 kit or a different capacity for my ThinkSystem SR630 V3?

Choose this 512GB kit when your SR630 V3 needs the maximum supported registered ECC capacity at 4800 MT/s; smaller kits use the same speed and latency but provide less total memory.

What does the 4800 MT/s rating mean once the modules are installed in a ThinkSystem SD650 V3?

The modules will run at 4800 MT/s with CL40 latency at 1.1 V, delivering PC5-38400 bandwidth while the registered ECC design maintains data integrity for server workloads.
