Server-grade capacity

This 256GB kit provides eight 32GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It targets administrators expanding memory in Thinkmate Supermicro SuperServer 621P-TR, 621P-TRT and 221P-C9R platforms that require registered error-correcting modules. The 1.10V operating voltage matches the DDR5 baseline for these qualified systems.

Registered DIMM integration

Each 288-pin RDIMM presents a 1Rx4 organisation that the memory controller addresses as a single rank per module. The registered buffer reduces electrical load on the server’s memory bus, allowing all eight slots to be populated without additional buffering hardware. ECC circuitry corrects single-bit errors and detects multi-bit faults to protect data integrity in mission-critical workloads.

Sustained-load stability

Modules are stress-tested under continuous load before shipment to verify reliable operation at the rated 4800 MT/s transfer rate. The absence of a heat spreader means airflow through the server chassis must meet the platform’s thermal design for the memory subsystem. Builders needing non-registered UDIMMs or capacities beyond 256GB should select a different kit.

Questions about this item

What is the CAS latency of these DDR5 4800 modules?

The kit runs at CL40, meaning each module has a CAS latency of 40 cycles at the rated 4800 MT/s speed.

How much heat do these registered ECC DIMMs produce during continuous operation?

They operate at 1.1 V with no heat spreader, so thermal output is low but depends on your server's airflow and DIMM spacing.

Which server models are confirmed compatible with this 256 GB kit?

The kit is validated for Thinkmate Supermicro SuperServer 621P-TR, 621P-TRT and 221P-C9R platforms.
