768 GB DDR5 4800 registered kit

This 768 GB kit contains six 128 GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It operates at 1.1 V and uses a 288-pin form factor designed for server motherboards. The modules are built with major OEM chips and carry a 4Rx4 organisation.

Who this suits and who should look elsewhere

The kit targets administrators upgrading an ASUS RS700-E11-RS4U 1U dual-socket server to its full supported capacity. Buyers who need unbuffered UDIMMs, lower capacities, or memory for consumer desktop boards should look elsewhere.

Deciding specification: 4Rx4 registered ECC DDR5

The 4Rx4 registered ECC DDR5 4800 configuration is the single detail that determines compatibility with the target ASUS server platform. Systems that require a different rank structure, voltage, or memory type will not accept these modules.
