64 GB DDR4-2400 ECC LRDIMM module

This 64 GB Samsung DDR4-2400 module is built for server platforms that require registered ECC memory. It operates at PC4-19200 speed with a CAS latency of 17 and runs at 1.2 V. The load-reduced design helps signal integrity on densely populated motherboards. Each stick is tested before it ships.

Who this suits and who should avoid it

This module suits administrators expanding memory in servers that accept 4Rx4 LRDIMMs. It is not for desktop PCs or workstations that only support unbuffered UDIMMs. Systems already populated with ECC UDIMMs cannot mix them with this registered format. Buyers needing non-ECC memory should look elsewhere.

Deciding specification: 4Rx4 LRDIMM organisation

The 4Rx4 load-reduced organisation is the single detail that determines compatibility. Only motherboards qualified for 4Rx4 LRDIMMs at DDR4-2400 will recognise the full 64 GB capacity. Verify the server memory qualification list before purchase.

Questions sur cet article

Will this 64GB DDR4-2400 LRDIMM operate correctly alongside existing DDR4 LRDIMM modules in my server?

This module runs at DDR4-2400 with CL17 latency and 1.2V voltage; the server memory controller will negotiate a common speed and timing with any other installed LRDIMMs.

How can I verify the 64GB DDR4-2400 ECC LRDIMM is functioning correctly after installation?

The server POST and BIOS will show 64GB capacity, DDR4-2400 speed, and ECC status; run a memory diagnostic such as MemTest86 to confirm error-free operation.

What is included with the M386A8K40BM1-CRC 64GB module and what must be purchased separately?

The box contains the single 64GB DDR4-2400 ECC LRDIMM stick; no additional cables, brackets, or software are required for installation in a compatible server.
