Kit composition and target system

This NEMIX RAM kit supplies 128GB of DDR5 memory as eight 16GB registered DIMMs. It is built for the ASUS RS700-E11-RS12U 1U dual-socket server. The modules run at 4800MT/s with CL40 latency and 1.1V operation. ECC and register buffering protect data integrity in mission-critical workloads.

Suitability and limits

The kit suits administrators upgrading or populating the named ASUS 1U server where registered ECC DDR5 is required. It will not fit systems that need unbuffered UDIMMs or SO-DIMMs. Buyers who need a different capacity per module or a non-registered memory type should look elsewhere.

Deciding specification

The registered ECC RDIMM form factor with 288 pins and 1Rx8 organisation is the single specification that determines compatibility. Only motherboards designed for DDR5 registered ECC memory can accept these modules. Verify the server memory qualification list before purchase.

Questions about this item

Does the kit include anything besides the eight 16 GB DDR5 4800 ECC RDIMM modules?

The package contains only the eight 16 GB modules that make up the 128 GB kit. No extra cables, brackets or software are supplied.

Should I choose this 128 GB kit or a smaller capacity for my ASUS RS700-E11-RS12U server?

This kit fills eight slots with 16 GB 1Rx8 registered DIMMs, matching the motherboard's validated configuration for maximum supported capacity.

What does the DDR5 4800 CL40 1.1 V rating mean once the memory is installed in the RS700-E11-RS12U?

The modules will run at 4800 MT/s with CAS latency 40 at 1.1 V, providing the rated PC5-38400 data rate for the server's registered memory channels.
