32GB DDR5 4800 ECC RDIMM for SuperMicro

This 32GB DDR5 4800 ECC RDIMM module is built for SuperMicro servers and workstations that require registered memory with error correction. It operates at 1.1V with a CAS latency of CL40 and uses a 2Rx8 rank configuration. The 288-pin form factor fits standard DDR5 RDIMM slots in compatible SuperMicro systems.

Registered DDR5 4800 limits and requirements

Registered DDR5 4800 memory runs at 4800 MT/s with PC5-38400 bandwidth and requires a platform that supports registered ECC RDIMMs at this speed. The memory controller must accept 1.1V operation and the 2Rx8 organisation. Mixing registered and unbuffered modules is not supported, and the system BIOS must be configured for ECC functionality to be active.

Verify SuperMicro compatibility before ordering

Check your SuperMicro motherboard or server documentation to confirm support for 32GB DDR5 4800 ECC RDIMMs with a 2Rx8 layout at 1.1V. Ensure the memory slots accept 288-pin registered modules and that the BIOS version enables ECC at the rated speed. Populating all channels with identical modules is recommended for stability in multi-socket configurations.

Questions about this item

Is this the 32GB stick or a 2x32GB kit?

This listing is a single 32GB module; the part number MR38400-328K1 confirms 1x32GB.

What does the 4800 speed mean when the module is installed?

The module runs at DDR5 4800 with CL40 latency at 1.10V, delivering PC5-38400 bandwidth once seated in a compatible SuperMicro server.

Is the 288-pin RDIMM slot the only fit, or will it work in a UDIMM slot?

The 288-pin RDIMM form factor requires a registered DIMM slot; it will not fit or function in a standard UDIMM socket.
