64GB DDR3 ECC RDIMM Kit

This A-Tech kit provides 64GB of DDR3 1866 memory across eight 8GB registered DIMMs. It is built for servers and workstations that require ECC error correction and registered signal buffering. The modules run at standard 1.5V with a CAS latency of 13.

Upgrade from lower-capacity DDR3 RDIMMs

The kit replaces smaller registered DDR3 sets when your workload demands more memory headroom for virtualization, databases or large datasets. The jump is worth it when your current configuration leaves free DIMM slots and the platform supports 8GB single-rank x4 modules at this speed.

Verify DDR3 RDIMM compatibility first

Confirm your system accepts DDR3 registered ECC DIMMs at 1866 MHz with a 1Rx4 organization. Desktop and laptop platforms cannot use these modules. Check the motherboard manual for supported capacities per slot and population rules before ordering.

Questions about this item

What motherboard slot does this 240-pin DDR3 RDIMM require?

It fits a standard 240-pin DDR3 DIMM socket on a server or workstation board that supports registered ECC memory.

What is the correct seating order for the eight 8 GB modules across the memory channels?

Follow the system manual’s channel population guide; install matching modules in the same channel slots and lock each DIMM until the ejector tabs click.

When should the 1.5 V registered ECC modules be replaced in a production server?

Replace them if the system logs correctable ECC errors that exceed the platform’s threshold or if memory diagnostics report uncorrectable failures.
