Server memory for Lenovo ThinkSystem SR655 V3

This 32 GB DDR5 ECC RDIMM is built for the Lenovo ThinkSystem SR655 V3 AI server. It delivers registered, error-correcting memory for workloads that require data integrity and stable operation. The single-module design suits upgrades that add capacity one slot at a time.

Registered DDR5 with 288-pin layout

The module uses a 288-pin DDR5 RDIMM form factor with a 2Rx4 organisation and runs at 1.10 V. Registered buffering reduces electrical load on the memory controller, while the absence of a heat spreader keeps the profile low for dense server configurations.

DDR5 5600 speed and CL46 latency

Rated at 5600 MT/s (PC5-44800) with CAS latency 46, the module operates within the DDR5 standard supported by the platform. Bandwidth and latency are fixed by this specification; systems needing higher throughput or lower latency would require memory rated beyond these limits.

Questions about this item

Does the DDR5 5600 interface cap the module at PC5-44800 bandwidth?

Yes, the DDR5 5600 specification corresponds to a PC5-44800 data rate, so this is the maximum standard bandwidth for the module.

What physical slot and pin count does this 288-pin RDIMM require?

It requires a standard 288-pin DDR5 RDIMM socket on the motherboard; the registered design also needs a server board that supports registered ECC memory.

How is the module installed and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that the 32 GB capacity and 5600 MT/s speed are recognised.
