A-Tech 64GB DDR4 3200 ECC RDIMM Kit

This 64GB kit contains four 16GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It is built for servers and workstations that require registered memory and single-rank x4 modules running at 1.2V.

Installing Registered ECC DIMMs

Modules install in standard 288-pin DDR4 slots but the system must support registered ECC memory or the kit will not function. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong channel order, or using a platform that only accepts unregistered memory.

Verify Platform Compatibility First

Check that your server or workstation motherboard explicitly supports DDR4 RDIMMs with ECC and single-rank x4 organisation. Confirm the maximum supported capacity per slot and the required population rules for quad-channel operation before ordering.

Questions about this item

How can I verify the kit is running at DDR4 3200 CL22 after installation?

Check the BIOS or a tool such as CPU-Z; each 16 GB module should report 3200 MT/s with CAS latency 22 at 1.2 V.

What comes in the box and is anything else required?

Four 16 GB DDR4 288-pin ECC RDIMM modules are included; no extra parts are needed if your server or workstation supports registered DDR4 memory.

Should I choose a different capacity or rank for my quad-channel server?

This 64 GB quad-channel kit uses four single-rank x4 modules; select it when your platform requires 1Rx4 registered DIMMs at 3200 MHz.
