Compatible DDR5 ECC RDIMM kit

This 128 GB kit contains two 64 GB registered DDR5 modules built for the ASUS RS700-E11-RS4U 1U dual-socket server. Each module runs at 4800 MT/s with CL40 latency at 1.1 V and uses a 2Rx4 organisation. The kit adds ECC-protected capacity to the qualified platform.

Suited for qualified ASUS servers

Administrators expanding the RS700-E11-RS4U with vendor-validated memory will find this kit matches the required specification. Builders targeting a different chassis, a workstation board, or a consumer platform should look elsewhere because the registration and pin-out are server-specific.

288-pin DDR5 RDIMM form factor

The modules use the standard 288-pin DDR5 RDIMM connector, so they seat only in slots wired for registered DDR5. A system expecting unbuffered UDIMMs or an older DDR generation cannot accept these modules.

Questions about this item

How much heat and power will the 1.10 V 4800 MT/s kit produce running 24/7 in the RS700-E11-RS4U?

The modules operate at 1.10 V with no heat spreader, so airflow through the 1U chassis handles cooling; registered DDR5 at this voltage draws less power per gigabyte than earlier generations.

What motherboard slots and firmware does the ASUS RS700-E11-RS4U need to accept this 2Rx4 ECC RDIMM kit?

The server must provide 288-pin DDR5 RDIMM slots and a BIOS that supports 64 GB 2Rx4 registered ECC modules at 4800 MT/s.

Can I mix this 128 GB kit with smaller DDR5 RDIMMs already installed in the same RS700-E11-RS4U?

Mixing ranks or capacities is possible only if the ASUS memory population rules for the RS700-E11-RS4U allow 2Rx4 modules alongside other registered DIMMs; check the server manual for supported configurations.
