64 GB DDR5 RDIMM for Lenovo SR685a V3

This 64 GB DDR5 5600 module is built as a 2Rx4 registered DIMM with ECC for the Lenovo ThinkSystem SR685a V3 rack server. It plugs into a standard 288-pin DDR5 slot and runs at 1.1 V to match the platform memory subsystem. The single-module kit lets administrators add capacity one slot at a time.

Sustained load behaviour with ECC registered design

Registered buffering places a register between the DRAM and the memory controller, reducing electrical load per channel during continuous operation. ECC corrects single-bit errors on the fly so data integrity is maintained across long compute runs. CL46 latency at 5600 MT/s keeps timing predictable when all channels are populated.

DDR5 5600 interface practical limits

The DDR5 5600 (PC5-44800) interface delivers its rated bandwidth only when the memory controller and BIOS are configured for that speed. Population rules for the SR685a V3 may reduce the operating frequency when multiple ranks fill a channel. Buyers who need higher transfer rates or lower latency than CL46 at this voltage should verify platform support before ordering.

Questions about this item

How much power does each 64GB DDR5 5600 CL46 registered ECC DIMM draw at its rated 1.1V?

The module operates at 1.1V, the standard voltage for DDR5 registered DIMMs; actual power draw depends on workload and the server's memory controller.

What must the Lenovo ThinkSystem SR685a V3 already provide for this 288-pin DDR5 RDIMM to function?

The server needs DDR5 RDIMM slots, support for 5600 MT/s registered ECC memory, and a BIOS that recognises 2Rx4 64GB modules.

Can this 64GB DDR5 5600 registered ECC DIMM be mixed with other DDR5 RDIMMs already installed in the server?

Mixing is possible only if the existing modules are also DDR5 registered ECC RDIMMs validated for the SR685a V3; matching speed, rank and voltage is recommended for stability.
