Suited environments and limitations

This kit targets administrators upgrading the ASUS RS700A-E12-RS12U dual-processor 1U server with registered ECC memory. It is not intended for desktop PCs, consumer motherboards or any platform that requires unbuffered DIMMs. Buyers needing non-ECC modules, lower capacities or different form factors should select a different product.

Deciding specification

The registered ECC RDIMM design with 2Rx4 organisation and CL40 latency at DDR5 4800 is the single attribute that determines compatibility with the target server. Systems that do not support registered ECC memory will not accept these modules.

Questions about this item

How much power does the 1.10 V DDR5 kit draw when the server runs continuously?

Each module operates at 1.10 V; total system draw depends on the ASUS RS700A-E12-RS12U platform and workload.

What must the ASUS RS700A-E12-RS12U already have for this 384 GB kit to function?

The server needs twelve free 288-pin DDR5 RDIMM slots and a BIOS that supports 64 GB 2Rx4 registered ECC modules.

Can I mix these CL40 4800 MT/s modules with slower DDR5 RDIMMs already installed in the RS700A-E12-RS12U?

All slots will run at the speed and latency of the slowest installed module; check the motherboard manual for population rules.
