4GB DDR3L ECC SODIMM for Servers

This 4GB DDR3L 1600 ECC SODIMM module targets servers and workstations that require error-correcting memory in a low-voltage laptop form factor. It runs at 1600 MHz with CL11 latency and operates at 1.35V. The unbuffered design fits 204-pin slots in compatible AMD and Intel platforms.

Replaces Samsung M474B5173QH0-YK0

The module is a direct equivalent for the Samsung M474B5173QH0-YK0 part, matching its 4GB capacity, DDR3L 1600 speed and ECC unbuffered specification. The upgrade is worth it when your system reports correctable memory errors, crashes under load or needs the data integrity that ECC provides for always-on workloads.

Verify DDR3L 1.35V ECC SODIMM support

Before ordering, confirm that your motherboard or laptop accepts DDR3L SODIMMs at 1.35V and explicitly supports ECC unbuffered modules. Standard consumer DDR3 slots often reject ECC sticks or run only at 1.5V, so consult the system manual or vendor specification sheet to avoid a mismatch.

Questions about this item

What slot type does this 204-pin DDR3L SODIMM require?

It fits a standard 204-pin DDR3 SO-DIMM slot keyed for 1.35 V low-voltage modules.

How is this ECC SODIMM installed, and what step is often missed?

Align the notch with the slot key, insert at an angle, then press down firmly until both side clips click into the notches — the click confirms full seating.

What maintenance or replacement will this unbuffered ECC module need later?

No routine maintenance is required; replace the module only if memory diagnostics report correctable errors that exceed the platform threshold.
