Server ECC RDIMM kit

This A-Tech 64GB kit contains eight 8GB DDR4 2400 registered ECC modules built for servers and workstations. Each stick runs at 1.2V with CL17 latency and a dual-rank 2Rx8 layout. The 288-pin DIMM form factor fits DDR4 registered memory slots only.

Verify registered DDR4 support

Check that your system explicitly supports DDR4 registered ECC RDIMM memory before ordering. Desktop and laptop platforms cannot use these modules. Consult the motherboard or server manual for approved memory configurations, population rules and maximum capacity per channel.

Replaces non-ECC or lower-capacity DDR4 RDIMMs

The upgrade is worthwhile when your workload needs error correction, higher density or both. If the current hardware already runs registered ECC DDR4 at 2400 MHz with sufficient capacity, the performance gain will be minimal.

Questions about this item

What comes inside the 64GB kit and is anything else required for installation?

The kit contains eight 8GB DDR4 2400 ECC registered DIMM modules. No extra parts are needed beyond a server or workstation motherboard with 288-pin DDR4 RDIMM slots.

How do I decide between this 64GB kit and a smaller or larger capacity option?

Choose this 64GB kit when your workload needs eight dual-rank 8GB modules running at 2400 MHz with CL17 latency; select a different kit only if your system's maximum supported capacity or channel population rules require a different total.

What does the 2400 MHz rating mean once the modules are running in my server?

The modules operate at DDR4 2400 (PC4-19200) with CL17 timing at 1.2V, delivering the rated bandwidth and latency as long as the platform's memory controller supports that speed and the DIMMs are populated according to the system's channel guidelines.
