32GB DDR5 ECC RDIMM for IBM-Lenovo Servers

This 32GB DDR5 module operates at 5600MHz with PC5-44800 bandwidth. It is built as a 288-pin registered DIMM with ECC for data integrity in server and workstation environments. The unit runs at the standard 1.10V DDR5 voltage. It serves as a direct replacement for the IBM-Lenovo 03NW600 part number.

Registered ECC with 2Rx8 organisation

The single specification that determines fit is the registered ECC RDIMM design with a 2Rx8 rank structure. This configuration requires a motherboard that supports registered memory and ECC error correction. Systems expecting unbuffered UDIMMs or non-ECC modules will not accept this stick. The CAS latency is rated at 40 cycles.

Fits DDR5 server slots.

Installation uses a standard 288-pin DDR5 DIMM slot on a compatible server or workstation board. The module draws 1.10V, matching the DDR5 baseline and leaving voltage headroom for dense population. No heat spreader is fitted, so airflow across the PCB is required. Consult the system manual for correct channel population rules.

Questions about this item

What does the DDR5 5600 speed mean once the module is installed in a server?

The module runs at 5600 MT/s, delivering PC5-44800 bandwidth when the platform memory controller operates at that data rate.

How does the 288-pin RDIMM interface and registered design affect compatibility?

The 288-pin DDR5 RDIMM fits DDR5 RDIMM slots only; the registered buffer adds one clock cycle of latency but allows higher capacities per channel.

What physical clearance and power does the 1.10 V 32 GB 2Rx8 module need to fit?

It requires a standard 288-pin DDR5 DIMM slot, operates at 1.10 V, has no heat spreader, and uses a 2Rx8 rank layout for dense server configurations.
