64GB DDR4-3200 ECC RDIMM for Lenovo Servers

This 64GB DDR4-3200 registered DIMM carries ECC and a 2Rx4 organisation. It is built for Lenovo platforms that require PC4-25600 registered memory. The module suits administrators expanding capacity in compatible enterprise systems.

Replaces lower-capacity or non-ECC DDR4 DIMMs

The jump is worthwhile when workloads demand registered error-correcting memory at 3200 MT/s. Systems limited to unbuffered modules or slower speeds cannot use this part. Buyers needing unregistered memory or consumer form factors should look elsewhere.

Fits Lenovo-qualified server slots

The RDIMM installs directly into registered DDR4 channels on supported platforms. It frees the builder from sourcing OEM-labelled sticks while maintaining 100% Lenovo compatibility. Ensure the host system accepts 2Rx4 registered modules before purchase.

Questions about this item

Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes — it is a 288-pin DDR4 registered DIMM built to the standard JEDEC form factor for server memory slots.

What is the correct seating step that installers often skip with this registered ECC module?

Align the notch, press firmly until both side latches click, then verify the module sits flush so the register engages the memory controller.

When should this 64 GB 2Rx4 ECC RDIMM be replaced?

Replace it if the system logs correctable ECC errors that climb over time or if memory diagnostics report uncorrectable failures.
