512GB DDR5 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5 4800 CL40 registered DIMMs built for the ASUS RS700A-E12-RS4U 1U dual-processor server. Each module runs at 1.10V with 2Rx4 organisation and 288-pin DDR5 form factor. The kit delivers 38400 MT/s bandwidth with error-correcting code for data integrity.

Suited for and not suited for

IT teams expanding memory in the named ASUS 1U server will find this kit validated for that platform. Buyers who need a different capacity, a lower latency, or memory for another server model should look elsewhere. Systems requiring unbuffered or non-ECC modules cannot use this registered ECC kit.

DDR5 4800 CL40 registered ECC spec

The DDR5 4800 CL40 registered ECC specification determines compatibility with the target ASUS server. Modules operate at 1.10V with 2Rx4 rank structure across 288 pins. Confirm the server memory configuration rules before ordering.

Questions about this item

Will the eight 64 GB DDR5 modules install cleanly alongside any existing DIMMs already in my ASUS RS700A-E12-RS4U server?

The kit provides eight 288-pin DDR5 4800 RDIMMs rated at 1.1 V and CL40; populate the remaining slots following the motherboard’s population rules so all channels run at the same speed and voltage.

How can I verify the 512 GB kit is running at the rated DDR5 4800 CL40 after installation?

Check the BIOS memory information or a tool such as dmidecode — each module should report 4800 MT/s, CAS 40, 1.10 V and registered ECC operation.

What exactly ships in the box and do I need any extra brackets or cables?

The package contains the eight 64 GB DDR5 4800 CL40 ECC RDIMM modules only; no brackets, cables or heat spreaders are included.
