Capacity and Compatibility

This kit provides 512GB of DDR4 3200 memory using eight 64GB registered ECC RDIMMs. It is validated for Thinkmate RAX, XS, XT, XH and S3 rackmount servers that require PC4-25600 4Rx4 modules at 1.2V.

Sustained Load Behaviour

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded workloads such as virtualisation, database serving and scientific compute. The 4Rx4 organisation and CL22 latency deliver stable throughput without the error accumulation seen in unbuffered alternatives.

Upgrade Context

The kit replaces smaller-capacity RDIMM sets or mixed-rank configurations that limit total system memory. The jump is worthwhile when workloads exceed current physical memory and the platform supports eight 288-pin slots populated with 4Rx4 registered modules.

Questions about this item

How much power does the 1.2V DDR4 3200 ECC RDIMM kit draw under sustained server loads?

Each 64GB module runs at 1.20V; total draw depends on the platform's memory controller and the 4Rx4 organisation, so consult the server's specifications for exact figures.

What must the Thinkmate rackmount already have to accept this 8×64GB registered kit?

The server needs free 288-pin DDR4 RDIMM slots that support 4Rx4 ECC modules at 3200 MT/s and a BIOS that recognises 512GB total capacity.

Will these CL22 4Rx4 modules work alongside older 2Rx4 DDR4 RDIMMs in the same Thinkmate chassis?

Mixing ranks is not recommended; the memory controller will train to the slowest common timing and may limit total rank count per channel, so populate identical modules for stability.
