384GB DDR5 ECC RDIMM kit

This 384GB kit contains six 64GB DDR5 4800MHz registered DIMMs with ECC and a CAS latency of 40. Each module operates at 1.1V and uses a 2Rx4 organisation on a 288-pin form factor. It is built for server platforms that require registered memory with error correction.

Server workloads needing maximum capacity

The kit suits administrators expanding memory on compatible DDR5 server boards that support 64GB registered modules and 2Rx4 density. It will not work in desktop PCs, workstations that require unbuffered DIMMs, or systems limited to lower densities or slower speeds. Builders needing non-ECC or consumer form factors should look elsewhere.

Registered DDR5 foundation for dense configurations

The modules plug into 288-pin DDR5 slots and rely on the platform memory controller for registered signalling and ECC scrubbing. Using six identical sticks simplifies population rules and leaves additional slots free for further expansion. The 1.1V operating voltage matches the DDR5 baseline, reducing power draw per gigabyte in large deployments.

Questions about this item

Does my server motherboard need to support DDR5 4800 ECC RDIMM modules to use this kit?

Yes, the kit contains six 288-pin DDR5 4800 registered ECC DIMMs, so the motherboard must accept DDR5 RDIMMs at that speed and voltage.

Will these 2Rx4 modules work if I keep some older 1Rx4 DDR5 RDIMMs in the same server?

Mixing ranks is possible on many platforms, but the memory controller will typically run all channels at the lowest common speed and rank configuration.

How can I confirm the kit is running at 4800 MT/s with CAS 40 after installation?

Check the BIOS memory information or a tool like dmidecode; it should report each 64 GB module at 4800 MT/s, CL40, 1.1 V, registered ECC.
