ASRock IMB-1900/1903 DDR5 Kit

This 1TB kit contains eight 128GB DDR5 RDIMMs built for ASRock Industrial IMB-1900 and IMB-1903 motherboards. The modules are registered, 4Rx4 ECC parts that run at 4800MT/s with a CL40 latency. They are designed for servers and workstations that require maximum memory capacity per slot.

Sustained-load behaviour

Registered buffering and ECC correction keep data integrity stable during continuous workloads. The 4Rx4 organisation spreads access across four ranks per module, helping the memory controller maintain throughput without timing violations. CL40 latency is consistent across all eight modules when the kit is fully populated.

Thermals, noise and power

Modules operate at 1.1V and have no heat spreaders, relying on chassis airflow for cooling. Power draw scales with the eight-module population but remains within standard DDR5 limits. No active cooling is included, so system fans must provide sufficient airflow over the 288-pin DIMMs.

Frågor om den här produkten

How much heat does the 1.1 V DDR5 kit generate when running all day in a fully populated server?

Each module operates at 1.1 V with no heat spreader, so sustained load produces modest heat that standard server airflow handles without extra cooling.

What motherboard must already be installed for this 1 TB kit to function?

The kit is validated for ASRock Industrial EATX boards IMB-1900 and IMB-1903 with 288-pin DDR5 RDIMM slots.

Can the 4Rx4 registered DIMMs share channels with other DDR5 ECC RDIMMs I keep?

Yes, provided the board supports mixed-rank populations; the 4Rx4 modules follow standard DDR5 ECC RDIMM electrical specs for compatible mixing.
