ASRock IMB-1900/1902 memory upgrade

This 64 GB kit supplies two 32 GB DDR5 4800 ECC RDIMM modules built for ASRock Industrial IMB-1900 and IMB-1902 motherboards. Registered buffering and on-die ECC protect data integrity in server and workstation workloads.

Sustained-load behaviour

Registered signalling and single-rank 1Rx4 organisation keep timing stable during long compute runs. CL40 latency at 4800 MT/s delivers consistent throughput without the jitter seen in unbuffered configurations.

Thermals noise and power

Modules operate at 1.1 V without heat spreaders, relying on chassis airflow for cooling. Low voltage reduces power draw per DIMM, and the absence of moving parts means silent operation in dense rack environments.

商品問答

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

Each module operates at 1.10 V, the standard voltage for DDR5 4800, so power draw stays at the JEDEC baseline for 32 GB registered DIMMs.

What motherboard slots and firmware are required to run this 288-pin ECC RDIMM kit?

The kit is validated for ASRock Industrial EATX boards IMB-1900 and IMB-1902 with DDR5 RDIMM slots and ECC support enabled in BIOS.

Can the 1Rx4 registered modules share channels with other DDR5 ECC RDIMMs of different capacity?

Yes, 1Rx4 registered DIMMs can populate open channels alongside other DDR5 ECC RDIMMs if the motherboard's memory population rules allow mixed capacities.
