Server memory kit

This 256GB kit contains eight 32GB DDR5 registered DIMMs built for THINKMATE SuperServer 521C-NR systems. Each module runs at 4800 MT/s with CL40 latency at 1.1V. ECC and registered buffering protect data integrity in multi-socket server workloads.

ECC registered design

Error-correcting code detects and corrects single-bit errors while the register reduces electrical load on the memory controller. The 1Rx4 organisation keeps signal integrity high across all eight slots. No heat spreader is fitted, so airflow in the chassis handles cooling.

288-pin DDR5 RDIMM form factor

The modules use the standard 288-pin DDR5 RDIMM layout keyed for 1.1V operation. They install only in platforms that support DDR5 registered ECC memory with this pin-out and voltage. Systems requiring unbuffered, non-ECC or a different DDR generation cannot use this kit.

Questions about this item

Will the 288-pin DDR5 RDIMM modules ever need replacement under normal server operation?

The modules are built with major OEM Samsung, Micron or Hynix chips and are stress-tested under load; no periodic replacement is required unless a module fails.

What limits sustained throughput on this 8×32 GB kit running at CL40?

The DDR5 4800 speed and CL40 latency set the maximum bandwidth ceiling for continuous workloads.

How much heat and power will the 1.1 V registered ECC kit produce running all day?

Operating at 1.10 V with no heat spreader, the registered DDR5 modules draw minimal power and run cool in typical server airflow.
