Server DDR4 256GB Kit
This 256GB kit contains two 128GB registered DDR4 modules built for servers and workstations that require ECC error correction. Each module runs at 3200MHz with CL22 latency and 1.2V voltage. The 288-pin RDIMM form factor fits compatible DDR4 server platforms. Buyers needing unbuffered UDIMM memory for consumer desktop boards cannot use this kit.
2x128GB Registered Capacity
The dual-rank 2S2RX4 organisation provides 256GB total capacity for memory-intensive workloads such as virtualisation, databases or AI model serving. Registered buffering reduces electrical load on the memory controller, allowing this density to operate stably at 3200MHz. Systems limited to lower maximum memory per slot or lacking registered DIMM support will not accept these modules.
1.2V DDR4 Thermals
Operating at the standard DDR4 voltage of 1.2V, the modules draw minimal power and generate modest heat under typical server loads. Major-brand DRAM chips and RIMLANCE quality testing contribute to consistent thermal behaviour in multi-DIMM configurations. Builds restricted to very low airflow chassis or extreme overclocking profiles may require additional cooling consideration.

Questions about this item
Will these 288-pin DDR4 RDIMMs work alongside my existing 3200 MHz registered modules?
Yes, both kits run at DDR4 3200 with CL22 timings and 1.2 V, so they can operate together when the motherboard supports mixed capacities.
How can I confirm the ECC registered function is active after installation?
Check the BIOS memory information screen; it should show 256 GB total, ECC enabled, and registered mode for each 128 GB module.
What comes in the RIMLANCE RRD25600DD4C2K256 kit and what must I source separately?
The kit includes two 128 GB 288-pin DDR4 3200 ECC registered RDIMMs; no cables, brackets or additional hardware are included.
