256GB DDR5 4800 ECC RDIMM kit

This 256GB kit contains eight 32GB registered DDR5 modules rated at 4800 MT/s with CL40 latency and 1.10V operation. It is built for THINKMATE SuperServer 421GE-TNRT and 421GE-TNRT3 systems that require ECC RDIMM memory. Each module uses a 1Rx4 organisation and 288-pin form factor.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller, helping signal integrity when all eight slots are populated. ECC detects and corrects single-bit errors during continuous server workloads. The 1.10V DDR5 voltage supports efficiency under long-running tasks. Modules are stress tested under load before shipment.

1Rx4 rank layout decides fit

The 1Rx4 rank configuration determines whether the memory controller can address the full 256GB across eight slots. Systems that expect a different rank per DIMM may not recognise the full capacity. Verify the server’s qualified vendor list for 1Rx4 RDIMM support before purchase.

Questions about this item

How much power does the 1.1V DDR5 4800 kit draw when the server runs continuously?

Each module operates at 1.10V, the standard DDR5 voltage, and the registered design helps the memory controller manage signal integrity efficiently across all eight 32GB sticks.

What must the Thinkmate Supermicro 421GE-TNRT or 421GE-TNRT3 already have to accept this 256GB kit?

The motherboard needs eight free 288-pin DDR5 RDIMM slots and a BIOS that supports 1Rx4 ECC registered modules at 4800 MT/s.

Will the CL40 1Rx4 modules work alongside any existing DDR5 RDIMMs already installed in the Thinkmate server?

Mixing ranks or latencies can prevent the system from training at 4800, so the safest approach is to populate all eight slots with this matched 8x32GB kit.
