Capacity and form factor

This is a 48 GB DDR5 SO-DIMM built for servers and workstations that accept 262-pin unbuffered modules. It runs at 5600 MT/s with CL46 latency and operates at 1.10 V. On-die ECC and a dual-rank 2Rx8 organisation provide error correction for data integrity.

Who this suits and who it does not

It fits systems that support unbuffered DDR5 SO-DIMMs with on-die ECC and can address 48 GB per slot. It is not for platforms that require registered or load-reduced DIMMs, nor for boards that cannot enable on-die ECC or dual-rank modules.

Deciding specification

The module is unbuffered with on-die ECC rather than registered with side-band ECC; this single attribute determines whether the memory will function in a given server platform.

Questions about this item

Should I pick the 48 GB module or combine smaller sticks to reach the same capacity?

A single 48 GB module fills one 262-pin SO-DIMM slot and leaves remaining slots free for future expansion, while using multiple smaller sticks would occupy more slots immediately.

What does the 5600 MT/s rating deliver in a server workload?

The DDR5-5600 speed provides 44800 MB/s peak bandwidth per module, so memory-intensive tasks such as virtualization or database caching can move more data per clock cycle at CL46 latency.

How does the DDR5 interface and on-die ECC affect real-world reliability?

The module runs at 1.10 V on the DDR5 standard, uses on-die ECC for internal error correction and presents a 2Rx8 unbuffered x72 organisation with 32 internal banks for improved signal integrity.
