384GB DDR5 4800 ECC RDIMM kit

This 384GB kit contains twelve 32GB DDR5 4800 registered DIMMs built for the ASUS RS520A-E12-RS24U server. Each module runs at 1.1V with CL40 latency and uses a 1Rx4 organisation. ECC and register buffering protect data integrity in continuous operation.

Suited for administrators filling all slots

Buyers who need a different capacity, speed or form factor should look elsewhere. The kit is not intended for consumer motherboards, laptops or workstations that accept only unbuffered memory.

12 × 32GB DDR5 4800 registered DIMMs

The twelve-module population matches the full slot count of the target server. Installing the complete kit ensures the platform sees the maximum supported capacity without mixing module sizes or ranks.

Questions about this item

What comes in the box and is anything else needed to install this memory kit?

The box contains twelve 32 GB DDR5 4800 ECC RDIMM modules for a total of 384 GB. No extra parts are required; the modules plug directly into the server's 288-pin DDR5 slots.

How do I decide between the different capacity or speed options for this server?

This kit is a single 384 GB configuration running at 4800 MT/s with CL40 latency and 1.10 V. Choose it when the ASUS RS520A-E12-RS24U needs the maximum supported capacity at the standard DDR5 4800 speed.

What does the 4800 MT/s rating mean once the modules are running in the RS520A-E12-RS24U?

The memory will operate at 4800 MT/s (PC5-38400) with CL40 timings at 1.10 V, delivering registered ECC bandwidth that matches the server's native DDR5 4800 specification.
