64GB DDR4 ECC Registered Kit

This 64GB kit contains four 16GB DDR4 ECC Registered DIMMs rated at 2133MHz with CL15 timings. It is designed for server workloads that require error correction and registered signalling. The modules operate at 1.2V and use a 288-pin form factor.

Verify Motherboard And Slot Count

Confirm that your system uses a Supermicro X10DRL-iT, X10DAC or X10DAI motherboard before ordering. With one processor installed, only 12 DIMM slots are available; with two processors, 24 slots are available. Mixing Registered and Load Reduced DIMMs is not supported in these systems.

Replaces Non-ECC Or Smaller RDIMMs

This kit upgrades from standard unbuffered memory or lower-capacity Registered DIMMs when data integrity and higher density are required. The jump is worth it for virtualisation hosts or database servers that need the full 64GB capacity across four modules.

Questions about this item

Does the kit ship as four separate 16 GB DIMMs or do I need to buy additional modules?

The package contains four 16 GB DDR4 2133 MHz ECC registered DIMMs, giving 64 GB total; no extra sticks are required.

Should I choose this 64 GB quad-rank kit or a different capacity for my Supermicro X10DRL-iT?

This 4×16 GB kit fills four slots with 2Rx4 modules at 1.2 V; larger RDIMM or LRDIMM options exist but mixing types is not supported.

Will the 2133 MHz rating run at that speed once installed in a dual-CPU Supermicro board?

Memory clocks down to the optimal speed for the installed processor and module count; with two CPUs all 24 slots are available.
