System-Specific DDR5 ECC RDIMM Kit

This 192GB kit contains two 96GB DDR5 5600 registered DIMMs built for the Lenovo ThinkSystem SR780a V3 rack server. It delivers ECC protection and registered signalling for stable operation in enterprise workloads.

Registered 288-Pin Modules Without Heat Spreaders

Each module uses a 288-pin DDR5 RDIMM form factor with 2Rx4 organisation and runs at 1.1V. The bare PCB design fits dense server slots where tall heat spreaders would block adjacent bays or airflow.

Verify Slot Count and Maximum Capacity Before

Confirm the SR780a V3 has enough free DDR5 RDIMM slots for two modules and that the platform supports 96GB per DIMM. Check the system documentation for population rules and any BIOS version requirements for this density.

Questions about this item

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

Yes, the kit is rated DDR5 5600 (PC5-44800) so the maximum standard data rate is 5600 MT/s.

What physical slot and pin count does each 96 GB module need?

Each module is a 288-pin DDR5 RDIMM and fits a standard DDR5 RDIMM socket on the Lenovo ThinkSystem SR780a V3.

How is the 2Rx4 registered kit installed, and which step is often missed?

Power down the server, open the chassis, align the notch on each 288-pin RDIMM with the slot key, press firmly until the ejectors click, then verify in BIOS that both 96 GB modules are detected at 5600 MT/s with ECC active.
