Lenovo ThinkSystem DDR4 3200 ECC RDIMM

This 32GB DDR4 3200 ECC registered DIMM is built for Lenovo ThinkSystem servers that require AMD processor support. It operates at 1.2V with CL22 latency and uses a 2Rx8 organisation. The module targets IT professionals upgrading memory in enterprise environments.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM design combined with a 2Rx8 rank structure at DDR4 3200 speed. Systems expecting unbuffered UDIMMs or a different rank configuration will not accept this module. Verify the server memory mode and slot population rules before ordering.

Tool-less slot installation with population rules

Installation is a standard DIMM insertion into the 288-pin slots and takes minutes, but the server’s memory population guide dictates which slots must be filled first. A common issue is mixing registered and unbuffered modules or populating slots in the wrong order, which prevents the system from posting.

Questions about this item

Will the 3200 MHz speed run at that rate in my Lenovo ThinkSystem server?

The module is rated for DDR4 3200 (PC4-25600) and will operate at that speed when the server’s memory controller supports it.

What does the registered ECC design mean for my system?

Registered ECC RDIMM adds a register to reduce electrical load and provides error correction for data integrity in AMD-based ThinkSystem servers.

Does the 288-pin RDIMM fit the memory slots in my ThinkSystem server?

Yes, the 288-pin DDR4 RDIMM form factor matches the DIMM slots used in compatible Lenovo ThinkSystem models.
