Compatibility and target systems

This kit is built for the ASUS RS700-E11-RS12U 1U dual-socket server. It provides 256GB across four 64GB registered ECC modules running at DDR5 4800. IT teams managing virtualisation hosts or database nodes in that chassis can install it without guessing compatibility.

Who should choose another option

Buyers who need unbuffered UDIMM memory for workstations or consumer motherboards cannot use these registered modules. Systems that require lower CAS latency than CL40 or a different voltage than 1.10V should look elsewhere.

Decisive specification

The registered ECC RDIMM form factor with 2Rx4 organisation and 1.10V operation determines whether the memory will post in the target server. Verify the platform requires registered DDR5 before ordering.

Questions about this item

Should I choose the 4 x 64 GB kit or a different capacity for the RS700-E11-RS12U?

The 256 GB kit provides four 64 GB modules to fill all channels on the ASUS RS700-E11-RS12U dual-socket server for maximum bandwidth.

What does DDR5 4800 mean once the modules are installed in the server?

The memory runs at 4800 MT/s with CL40 latency at 1.1 V, delivering PC5-38400 throughput under load.

How does the 288-pin RDIMM interface cap performance in practice?

Registered 288-pin DDR5 limits each module to 4800 MT/s and requires the server memory controller to support ECC registered operation.
