1.5 TB DDR5 server kit

This NEMIX RAM kit delivers 1.5 TB of DDR5 4800 memory in twelve 128 GB modules. It is built for the ASUS RS700A-E12-RS4U dual-processor 1U server and carries ECC registered RDIMM specifications. Each module runs at 1.10 V with a CAS latency of CL40. The kit targets administrators scaling memory capacity in compatible enterprise platforms.

Who this suits and who should look elsewhere

This kit suits IT teams upgrading the specified ASUS 1U server to its maximum supported density with validated ECC registered modules. It is not for buyers needing consumer UDIMM form factors, non-ECC memory, lower voltages, or modules that fit desktop or workstation platforms outside the listed compatibility.

Deciding specification: 4Rx4 rank configuration

The 4Rx4 rank layout determines whether the server memory controller can address the full 1.5 TB across all twelve slots. Verify the platform documentation accepts 4Rx4 RDIMMs at DDR5 4800 before purchase; an incompatible rank structure will prevent boot or reduce usable capacity.

Questions about this item

Will the 12x 128 GB DDR5 RDIMM kit require any firmware updates or periodic reseating to stay stable in the ASUS RS700A-E12-RS4U?

The modules are rigorously stress-tested for compatibility with the RS700A-E12-RS4U and ship ready to install; no firmware updates or scheduled reseating are specified for the memory itself.

What thermal or throttling limit appears first when the 1.5 TB kit runs at DDR5 4800 CL40 continuously?

Each RDIMM operates at 1.10 V with a CL40 latency; the registered design and ECC circuitry manage signal integrity, so the platform's memory-controller thermal envelope is the first practical ceiling.

How much extra heat and power does the 12-module kit add when the server runs all day?

Twelve 128 GB RDIMMs at 1.10 V draw modest power per module; total heat scales with capacity but stays within normal DDR5 registered DIMM limits for a 1U dual-processor chassis.
