Lenovo ThinkSystem SR655 V3 DDR5 kit

This 384 GB kit contains six 64 GB DDR5 5600 MHz registered ECC RDIMMs built for the Lenovo ThinkSystem SR655 V3 AI server. Each module runs at 1.1 V with CL46 latency and a 2Rx4 organisation. The 288-pin form factor matches the server’s memory slots exactly.

Installation and common issues

The modules are keyed for DDR5 slots and seat with a firm push until the retention clips click. Install all six sticks in the channels recommended by the server manual to enable full bandwidth. Mixing ranks or speeds can prevent the system from posting, so keep the kit together as shipped.

Suitable buyers and mismatched needs

This kit suits administrators expanding a single SR655 V3 to its maximum supported capacity with validated ECC registered memory. Buyers who need unbuffered UDIMMs for workstation boards, lower-density modules for partial population, or memory qualified for a different server platform should select a different product.

Questions about this item

How can I confirm the 384GB DDR5 5600MHz kit is running at CL46 1.1V after installation?

Enter the BIOS or use a tool like CPU-Z to verify the memory reports 5600 MT/s, CAS latency 46, voltage 1.1 V and that all six 64 GB modules are detected as registered ECC RDIMMs.

What exactly ships in the box and do I need any extra brackets or cables?

The package contains the six 64 GB 288-pin DDR5 RDIMM modules only; no heat spreaders, brackets, cables or additional hardware are included or required for installation.

Should I choose the 6x64GB 2Rx4 CL46 kit or a different capacity for my ThinkSystem SR655 V3?

Select this 384 GB kit when the server’s qualified vendor list calls for 2Rx4 registered ECC RDIMMs at 5600 MT/s CL46; other capacities or ranks may not match the platform’s validated memory configurations.
