DDR5 ECC RDIMM for Servers and Workstations

This 16GB registered DIMM delivers error-correcting code memory for 288-pin DDR5 platforms. It operates at 4800 MT/s with a CAS latency of 40 and a low 1.1V supply. The module is designed for systems that require registered buffering and ECC integrity.

Not for Desktop or Mixed ECC Configurations

Standard desktop boards cannot use registered ECC RDIMMs and will not post with this module installed. It also cannot be mixed with unbuffered or load-reduced ECC memory in the same system. Buyers needing non-ECC consumer memory or a different form factor should select another product.

JEDEC DDR5 4800 Registered Specification

The single 1Rx8 rank module complies with the JEDEC PC5-38400 standard for DDR5 registered DIMMs. This specification determines whether the part matches the server or workstation memory slot requirements. Verify the platform manual calls for DDR5 4800 ECC RDIMM before ordering.

Questions about this item

Should I choose the 16GB DDR5 4800 CL40 1Rx8 registered ECC module or a different capacity?

This listing is a single 16GB DDR5 4800 CL40 1Rx8 registered ECC RDIMM. Select it when your server or workstation requires registered ECC memory and you want a 16GB module at 4800 MT/s.

What does the 4800 MT/s rating deliver once the module is installed?

The module runs at DDR5 4800 (PC5 38400) with CL40 latency at 1.1V. Actual throughput depends on the platform memory controller and how many DIMMs populate each channel.

How does the 288-pin DDR5 registered ECC interface limit what I can use this with?

The 288-pin DDR5 RDIMM form factor with registered ECC works only in platforms that support registered DDR5 ECC memory. It will not fit or function in unbuffered desktop boards or LRDIMM slots.
