1 TB DDR5-4800 ECC RDIMM kit

This 1 TB memory kit contains sixteen 64 GB DDR5-4800 registered DIMMs built with ECC for error correction. It operates at 1.1 V with a CAS latency of CL40 and uses a 2Rx4 organisation across 288 pins. The kit is configured for the ASUS RS700-E11-RS12U 1U dual-socket server.

Compatibility and use cases

The modules suit administrators upgrading the named ASUS 1U server to its maximum supported capacity with validated ECC registered memory. Builders targeting other platforms, consumer motherboards, or systems requiring unbuffered DIMMs should select a different kit.

DDR5-4800 CL40 2Rx4 specification

The decisive specification is the DDR5-4800 speed grade combined with CL40 latency, 2Rx4 rank structure and registered ECC operation at 1.1 V. Only systems qualified for this exact combination will recognise and run the kit at its rated settings.

Questions about this item

What server platform must I already have for this 1TB kit of 16×64GB DDR5 4800 CL40 2Rx4 1.1V ECC RDIMMs to work?

This kit is built for the ASUS RS700-E11-RS12U 1U dual-socket server; the modules are 288-pin DDR5 RDIMMs that only fit that platform.

How will these registered 2Rx4 modules behave if I keep older DDR5 RDIMMs in the same ASUS RS700-E11-RS12U?

All slots in the RS700-E11-RS12U must use identical DDR5 4800 registered ECC modules; mixing different ranks or speeds will prevent the system from posting.

How can I verify the full 1TB is running at DDR5 4800 CL40 after installation?

Enter the BIOS on the ASUS RS700-E11-RS12U and confirm the memory speed shows 4800 MT/s, CAS latency 40, and total capacity 1TB across all 16 slots.
