64GB DDR4 ECC RDIMM kit

This 64GB kit contains two 32GB DDR4 2933 registered DIMMs with ECC and CL21 latency. It is built for servers and workstations that require error-correcting registered memory running at 1.2V. The modules use major OEM chips from Samsung, Micron or Hynix and carry the part number MR23400-324K2.

Check motherboard RDIMM support

Verify that your system accepts 288-pin DDR4 registered DIMMs and supports a 2Rx4 rank configuration at 2933 MT/s. The board must be compatible with ECC registered memory and able to operate at 1.20V. Consult the motherboard manual for maximum capacity per slot and approved memory population rules before ordering.

Upgrade from non-ECC or lower capacity

This kit replaces standard unbuffered memory or smaller registered kits in compatible ASRock Rack EPYCD8-2T series motherboards. The jump is worth it when workloads demand data integrity through ECC and the higher density of 32GB modules. Systems limited to unbuffered DIMMs or lower speeds cannot use this registered kit.

Questions about this item

Does the kit include only the two 32 GB modules or any extra parts?

The package contains the 64 GB kit as two 32 GB DDR4 2933 CL21 ECC RDIMM modules and nothing else.

Why choose the 64 GB 2Rx4 kit instead of a lower capacity option?

This 2 x 32 GB kit delivers 64 GB total with dual-rank 2Rx4 organisation, matching the ASRock Rack EPYCD8-2T memory slots for maximum supported capacity.

What does the 2933 MT/s rating mean once the modules are installed in the server?

The memory runs at DDR4 2933 (PC4-23400) with CL21 latency at 1.20 V, providing registered ECC bandwidth for the compatible ASRock Rack platform.
