Compatible Supermicro BigTwin SYS-222BT-HER

This NEMIX RAM kit supplies 64 GB of DDR5 registered ECC memory across four 16 GB modules. It is built for the Supermicro BigTwin SuperServer SYS-222BT-HER and runs at 6400 MHz with a CAS latency of 52 at 1.10 V.

Suited for registered ECC server slots

The 288-pin RDIMM format with 1Rx8 organisation fits servers that require registered error-correcting memory. Workstations or desktops that only accept unbuffered non-ECC DDR5 modules cannot use this kit.

Simple DIMM installation

Each module inserts vertically into a 288-pin DDR5 slot and locks with the retention clips. Mixing these registered sticks with unbuffered memory or populating slots in an unsupported order will prevent the system from posting.

Questions about this item

Does this 4-module kit require a Supermicro SYS-222BT-HER motherboard with four available 288-pin DDR5 RDIMM slots?

Yes, the kit contains four 16GB 288-pin DDR5 RDIMM modules and is validated for the Supermicro SYS-222BT-HER, so four compatible slots are needed.

Can I keep any existing DDR5 1Rx8 ECC RDIMMs installed alongside these four 16GB modules?

Mixing ranks or capacities may prevent the system from training at 6400 MT/s; for best results populate all four channels with this matched 1Rx8 CL52 kit.

How can I confirm the kit is running at 6400 MT/s with CL52 timings after installation?

Enter the system BIOS or use a tool such as dmidecode to verify the reported speed shows 6400 MT/s and the CAS latency reads 52.
