32GB DDR5 4800 ECC Registered RDIMM

This 32GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It is built as a 2Rx8 registered DIMM with on-die ECC for error correction. The part targets servers and workstations that require registered memory and cannot use unbuffered or load-reduced types.

288-pin installation and mixing rules

The module fits standard 288-pin DDR5 slots and requires no tools beyond normal DIMM insertion. The main risk is mixing this registered ECC stick with unbuffered or load-reduced memory, which the manufacturer states will not work. All installed DIMMs should match in capacity, speed and vendor for stable operation.

For JEDEC-compliant server fleets

This upgrade suits administrators extending the life of existing DDR5-4800 platforms or building new JEDEC-compliant nodes. It is not for desktop PCs that accept only unbuffered memory, nor for systems that require load-reduced DIMMs or speeds beyond 4800 MT/s.

Questions sur cet article

How can I confirm the DDR5 4800 module is running at the correct speed and latency after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 4800 MT/s with CAS latency 40.

What is included with the 32 GB RDIMM and what must be purchased separately?

The box contains the single 288-pin ECC Registered DIMM. No cables, brackets or additional modules are supplied.

Which capacity and rank configuration should I select for a server that requires 2Rx8 registered ECC memory?

Choose this 32 GB 2Rx8 module; it matches the registered ECC RDIMM specification and cannot be mixed with unbuffered or load-reduced DIMMs.
