256GB DDR4 ECC RDIMM kit

This registered ECC memory kit provides 256GB across four 64GB modules for ThinkMate XF4-24S3 workstations. It runs at DDR4 3200 with CL22 latency and 1.2V operation. The 4Rx4 organisation and 288-pin RDIMM form factor target server and workstation platforms that require error correction and registered signalling.

Sustained-load stability

Each module is stress tested under load to verify reliability during continuous operation. Registered buffering and ECC correction maintain data integrity when the system runs at full capacity for extended periods. The 1.2V rating keeps power draw consistent without thermal spikes that can throttle performance over time.

DDR4 3200 interface limits

The PC4-25600 standard caps peak transfer rate at 25600 MB/s per module. Four ranks per DIMM increase electrical loading, so maximum populated speed depends on the memory controller capabilities of the specific ThinkMate platform. CL22 latency sets the minimum access delay at this data rate.

Questions about this item

How much power does the 1.2 V 256 GB kit draw under sustained load?

Each module runs at 1.20 V DDR4 standard voltage; total system draw depends on the platform and workload.

What must the motherboard provide for these 288-pin RDIMMs to function?

The board needs DDR4 RDIMM slots that support registered ECC memory and 4Rx4 organisation.

Will the CL22 timing work with slower DDR4 modules already installed?

All modules run at the lowest common speed and latency; mixing ranks or speeds may reduce stability.
