256GB DDR5 ECC RDIMM Kit

This 256GB kit contains four 64GB DDR5 4800 registered DIMMs built for the ASUS RS700A-E12-RS12U 1U dual-processor server. Each module runs at 1.10V with CL40 latency and 2Rx4 organisation. The ECC registered design protects data integrity in mission-critical workloads.

Who This Suits and Who It Does Not

System administrators expanding memory in the named ASUS 1U server will find guaranteed compatibility and validated stability. Buyers needing unbuffered UDIMMs, non-ECC modules, different capacities, or memory for any other platform should look elsewhere.

Deciding Specification: 288-Pin DDR5 RDIMM

The 288-pin DDR5 RDIMM form factor with ECC and registered buffering is the single attribute that determines fit. Only systems designed for DDR5 registered ECC DIMMs can accept this kit; any other memory type will be physically or electrically incompatible.

Questions about this item

How much heat and power does the 1.10 V DDR5 kit draw in a 1U server that runs all day?

The modules operate at 1.10 V DDR5 standard voltage; registered ECC RDIMM design and 2Rx4 organisation help the memory controller manage thermal load in a continuously running 1U chassis.

What must the ASUS RS700A-E12-RS12U motherboard already provide for this 256 GB kit to function?

The board needs 288-pin DDR5 RDIMM slots, registered ECC support, and a CPU memory controller qualified for 4800 MT/s PC5-38400 operation across four channels.

Will the CL40 4800 MT/s modules run stably beside older DDR5 DIMMs I keep in the same server?

All four 64 GB modules are matched at CL40 4800 MT/s 1.10 V; mixing with different speeds, latencies or ranks forces the system to down-clock to the slowest common settings.
