64GB DDR4 ECC RDIMM Kit

This A-Tech kit provides 64GB of DDR4 2666 MHz registered ECC memory across eight 8GB dual-rank modules. It is built for servers and workstations that require error-correcting registered DIMMs for data integrity and system stability. Desktop and laptop computers cannot use these modules.

Upgrade from non-ECC or lower-capacity registered

The jump is worth it when your workload demands error correction and registered signalling for reliable operation under sustained loads. Adding this kit increases total memory capacity and replaces unbuffered or non-ECC modules that lack the error detection required by many server platforms.

Installation follows standard 288-pin DIMM seating

Align the notch on each module with the slot key and press firmly until the retention clips lock. Common issues include mixing registered DIMMs with unbuffered memory, populating slots in the wrong channel order, or installing in a desktop board that does not support registered ECC. Consult the system manual for the correct population sequence.

Questions about this item

What slot type and pin count do these DDR4 RDIMMs require?

They use standard 288-pin DDR4 DIMM slots for registered server memory.

What is the correct seating order for the 8 modules in a multi-channel server board?

Follow the motherboard manual to populate channels evenly; a common error is filling one channel completely before the others.

When should an 8 GB 2Rx8 module from this kit be replaced?

Replace a module if the system logs repeated ECC correctable errors or an uncorrectable error on that specific DIMM.
