System-specific DDR5 ECC RDIMM kit

This 256 GB kit contains two 128 GB registered DDR5 modules built for the SuperMicro BigTwin SuperServer SYS-222BT-HER. Each module runs at 6400 MHz with CL52 latency at 1.1 V and uses a 2Rx4 organisation. The ECC RDIMM design targets enterprise workloads that require error correction and registered signalling.

Verify DIMM slots and population rules

Confirm the server has enough free 288-pin DDR5 RDIMM slots for two modules and check the platform's qualified-vendor list for 6400 MHz registered parts. The motherboard manual defines maximum capacity per channel and any required slot-filling order. Ensure the system BIOS is at a version that supports this memory speed and density.

Kit delivers matched-pair reliability

The two modules are packaged together as a tested pair, so they share identical timings, voltage and rank configuration. This reduces the risk of mismatch errors during multi-channel training. No heat spreaders are included, so airflow in the chassis must meet the server vendor's cooling guidelines for bare DRAM.

Questions sur cet article

Does the kit include both 128 GB modules or do I need to buy a second stick?

The kit ships as a matched pair of two 128 GB modules, giving 256 GB total with nothing extra to purchase.

Why choose the 256 GB CL52 2Rx4 kit instead of a smaller capacity?

The 2Rx4 organisation on each 128 GB module delivers the full 256 GB at 6400 MT/s while keeping latency at CL52 and voltage at 1.1 V.

What does the 6400 MT/s rating mean once the modules are installed in the SuperMicro SYS-222BT-HER?

The server will run the memory at 6400 MT/s with ECC and registered buffering active, providing 51200 MB/s bandwidth per channel at the rated CL52 timing.
