NEMIX RAM 32GB DDR5 4800 ECC RDIMM Kit

This kit supplies 32GB of DDR5 4800 registered ECC memory in two 16GB modules built for the ASUS RS700-E11-RS12U 1U dual-socket server. It runs at 1.1V with CL40 timing and uses a 288-pin RDIMM form factor. Each module is a single-rank 1Rx8 design sourced from major OEM DRAM. No heat spreaders are fitted.

Server administrators and IT teams

Administrators who need validated, registered ECC memory for this specific ASUS 1U platform can install the kit with confidence. Workstations or desktops that require unbuffered non-ECC DDR5 will not accept these registered modules. Builders needing higher capacities or different speeds must select alternate part numbers.

Registered ECC RDIMM with CL40 latency

The registered ECC design adds a buffer that stabilises heavy multi-DIMM loads in dual-socket servers. CL40 CAS latency at 4800 MT/s defines the access timing for this kit. Systems that require unbuffered memory or lower latency grades cannot use these modules.

Questions about this item

What DDR5 speed and CAS latency does this kit run at?

The kit is rated for DDR5 4800 MT/s with a CAS latency of CL40.

Does this ECC RDIMM kit have a heat spreader, and what pin count does it use?

No heat spreader is included; each module uses the standard 288-pin DDR5 RDIMM form factor.

What is the correct slot population order for the ASUS RS700-E11-RS12U 1U dual-socket server?

Consult the server manual; typically you fill the same numbered DIMM slot on each CPU channel first, then the next channel, to maintain balanced memory interleaving.
