Server-grade DDR5 ECC RDIMM kit

This 512 GB kit consists of eight 64 GB DDR5 4800 MHz registered DIMMs with ECC and a CL40 latency. It is built for ASRock Industrial EATX motherboards IMB-1900 and IMB-1902. The modules run at 1.1 V and use a 288-pin 2Rx4 organisation.

Upgrade from non-ECC or lower-capacity DDR5

The registered design and error-correcting code protect data integrity in multi-socket server workloads. The jump is worth it when your application demands maximum DIMM population and sustained throughput without silent data corruption.

Eight slots filled for 512 GB total

The kit occupies every slot on compatible boards, delivering the highest supported capacity per channel. Headroom ends at the platform's eight-DIMM limit; larger datasets require a different motherboard or cluster approach.

Questions about this item

Will the 288‑pin DDR5 RDIMM modules fit the ASRock IMB‑1900 and IMB‑1902 EATX motherboards?

Yes, the kit is built for those boards; each 64 GB stick uses the standard 288‑pin DDR5 RDIMM form factor that slots directly into the server‑class DIMM sockets on the IMB‑1900 and IMB‑1902.

What is the correct order for populating the eight 2Rx4 modules on the IMB‑1900/1902, and which step is most often missed?

Fill the eight slots following the motherboard’s channel‑population guide — usually alternating channels per CPU — and the step most people skip is enabling ECC and registered mode in the BIOS before first boot.

When should the 1.10 V DDR5 ECC RDIMM kit be checked or replaced in a 24/7 server?

Run a memory diagnostic at each planned maintenance window; if correctable ECC error counts start climbing or the system logs uncorrectable errors, replace the affected 64 GB module immediately.
