Server Memory Upgrade

This RIMLANCE module is a 16GB DDR4 2933 ECC Registered RDIMM built for servers and workstations that require error-correcting memory. It uses a 288-pin form factor and operates at 1.2V with CL21 latency. The single-rank 1Rx4 design helps maintain signal integrity on populated memory channels.

Capacity And Speed Step

The module upgrades a system from lower-capacity or slower DDR4 RDIMMs by adding 16GB at 2933 MT/s while keeping registered buffering and ECC active. The jump is worth it when workloads exceed current memory headroom or when replacing non-ECC modules in a platform that mandates registered error correction. It does not fit desktop boards that accept only unbuffered DIMMs.

Installation Notes

Installation follows the standard 288-pin DDR4 keying; align the notch and press until the latches engage. Common issues arise when mixing registered and unbuffered DIMMs or when the BIOS lacks the latest microcode for 2933 operation. Verify the platform supports DDR4 registered memory before purchase.

Questions about this item

Does the 288-pin DDR4 RDIMM require a registered-memory slot?

Yes, the module is a registered DDR4 RDIMM and must be installed in a server or workstation motherboard that supports registered ECC memory.

What is the correct orientation for seating the 288-pin module?

Align the notch on the gold edge connector with the key in the DDR4 slot, press down firmly until both side clips click into place.

When should the 16 GB CL21 ECC module be replaced?

Replace it if system logs report uncorrectable ECC errors, if memory diagnostics fail repeatedly, or when a capacity upgrade is required.
