System-specific DDR5 kit

This 768GB kit contains twelve 64GB DDR5 4800 registered DIMMs built for the ASUS RS700A-E12-RS12U dual-processor 1U server. IT teams and system integrators use it to maximise memory capacity in that specific platform.

DDR5 4800 registered ECC constraints

Registered DIMMs with on-die ECC require a motherboard chipset and BIOS that support registered operation and the PC5-38400 data rate; consumer boards and unbuffered slots will not accept these modules. The 1.1V operating voltage is fixed by the DDR5 specification for this speed grade.

12 x 64GB 2Rx4 population

The kit fills all twelve slots with dual-rank 2Rx4 modules, delivering the maximum supported capacity per channel for this server model. Buyers needing fewer modules or a different rank configuration must select another part number.

Questions about this item

Which capacity kit should I choose for the ASUS RS700A-E12-RS12U server?

The kit provides 768 GB total using 12 modules of 64 GB each, matching the 12-slot population for this model.

What does DDR5 4800 mean for actual throughput in this system?

The modules run at 4800 MT/s with CL40 latency and 1.10 V, giving the rated PC5-38400 data rate when all 12 slots are filled.

What does the 288-pin ECC RDIMM interface cap in practice?

The 288-pin DDR5 RDIMM form factor with 2Rx4 organisation and registered ECC is the physical and electrical limit for this server platform.
