Lenovo ThinkSystem 32GB Registered DIMM
This Lenovo 4ZC7A08709 module adds 32GB of DDR4 2933 registered memory to compatible ThinkSystem servers. It is built for administrators expanding capacity in validated Lenovo platforms. Buyers needing unbuffered UDIMMs or consumer SO-DIMM form factors cannot use this part.
Thermal and power profile
Operating at 1.20V, the registered DIMM draws less power per gigabyte than earlier DDR4 modules while maintaining signal integrity across 288 pins. The register buffers address and command lines, reducing electrical load on the memory controller during sustained workloads. No active cooling is required beyond standard server airflow.
TruDDR4 authentication benefit
Each module carries a unique signature that the ThinkSystem firmware verifies at boot, enabling memory stretch goals only when genuine TruDDR4 DIMMs are detected. This authentication unlocks the full qualified-speed envelope across supported SR and ST platforms. Systems without TruDDR4 validation will not activate these extended timing parameters.

Vprašanja o tem izdelku
How is the 288-pin DIMM installed in a ThinkSystem server, and which step is commonly missed?
Align the notch on the 288-pin DIMM with the slot key, press firmly until both ejector tabs click shut, then verify in the BIOS that the 2933 MHz registered speed is recognised.
What maintenance or replacement will the 32GB TruDDR4 module need later?
No routine maintenance is required; if a memory error occurs, replace the module with another 32GB DDR4 2933 registered DIMM of matching rank and voltage.
What limit appears first when the 1.20V registered memory runs under sustained load?
The DDR4 2933 (PC4 23400) data rate is the fixed ceiling; sustained workloads cannot exceed this transfer speed.
