Samsung 16GB DDR4-3200 ECC UDIMM

This Samsung DDR4 module delivers 16GB of ECC unbuffered memory at 3200 MT/s. It is built for workstations and servers that require error-correcting code protection. The UDIMM form factor fits standard desktop DIMM slots. Systems without ECC support in the chipset or CPU will not benefit from the error correction.

OEM green PCB with gold contacts

The module uses a bare green PCB with gold-plated edge contacts and no heatsink. This low-profile design clears most CPU coolers and dense slot layouts. Gold contacts resist oxidation for reliable long-term seating. The OEM packaging omits retail shielding, so handle by the edges to avoid static damage.

No bundled software or accessories

Only the memory module itself is supplied. There is no configuration utility, diagnostic CD or mounting hardware included. System BIOS or UEFI manages timing and ECC enablement automatically. Buyers needing installation tools or validation software must source them separately.

Questions about this item

Does the DDR4-3200 interface cap the memory speed at 3200 MT/s on a compatible platform?

Yes, the DDR4-3200 rating means the module is specified to run at up to 3200 MT/s when the motherboard and processor support that data rate.

What physical slot and form factor does the M391A2G43BB2-CWE need to fit?

It is a UDIMM module built for a standard desktop DDR4 DIMM socket.

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

Align the notch with the slot key, press firmly until the retention clips click, then verify in BIOS that ECC function is enabled.
