768GB DDR5 ECC RDIMM server kit

This 768GB kit contains six 128GB DDR5 4800 ECC registered DIMMs built for the ASUS RS700-E11-RS12U 1U dual-socket server. Each module runs at 1.1V with CL40 latency and uses a 4Rx4 organisation. The 288-pin RDIMM form factor fits the server's memory slots directly.

Suited for memory-heavy server workloads

The capacity and registered ECC design suit virtualisation hosts, database nodes and compute clusters that need maximum DIMM density per channel. Systems requiring unbuffered UDIMMs, non-ECC memory or lower-capacity modules for consumer platforms cannot use this kit.

4Rx4 rank configuration per module

Each 128GB DIMM presents a quad-rank 4Rx4 layout that the memory controller must support. Verify the server's qualified vendor list accepts 4Rx4 registered DDR5 at 4800 MT/s before installation.

Questions about this item

What motherboard slot count and DDR5 support does my server need to accept all six 128GB RDIMMs?

The ASUS RS700-E11-RS12U must provide at least six 288-pin DDR5 RDIMM slots and run them at 4800 MT/s with registered ECC modules.

Will the registered ECC design of these 4Rx4 modules conflict with any unbuffered or non-ECC DIMMs I might leave in other slots?

Registered ECC RDIMMs cannot share a channel with unbuffered or non-ECC DIMMs; all populated slots must use registered ECC modules for the server to post.

How can I confirm the kit is running at the rated 4800 MT/s CL40 after installation?

Check the BIOS memory information or OS tools such as dmidecode to verify each module reports 4800 MT/s, CL40 latency and 1.1 V operation.
