16GB DDR4 ECC SODIMM for servers

This 16GB DDR4 2933MHz module targets server and workstation systems that require error-correcting memory. It runs at 1.2V with a CL21 latency and uses an unbuffered 260-pin SO-DIMM form factor. The module replaces the Hynix HMA82GS7DJR8N-WM part and is tested for reliable operation.

DDR4 2933 ECC limits

ECC unbuffered SO-DIMMs only function on platforms that explicitly support error correction and the DDR4 2933 standard. The memory will not provide ECC protection on consumer laptops or desktops lacking the feature. Maximum capacity and speed depend on the host system's memory controller and BIOS implementation.

Check your system before ordering

Verify that your motherboard or laptop accepts DDR4 ECC unbuffered SO-DIMMs at 2933MHz. Confirm the maximum supported capacity per slot and total system limit in the manual. Ensure the BIOS is updated to recognise the module and enable ECC functionality if required.

Questions about this item

Is this 16GB module the right capacity for my upgrade, or should I add multiple sticks?

This single module provides 16GB of DDR4 2933MHz ECC memory. Check your laptop or workstation manual for the maximum supported capacity per slot and total system limit before deciding whether one stick is sufficient.

What does the 2933MHz speed actually deliver in a real system?

The module runs at DDR4 2933MHz (PC4-23400) with CL21 latency at 1.20V. Actual throughput depends on your platform's memory controller and whether it supports this exact speed; the system will downclock automatically if a lower speed is required.

Is the 260-pin SO-DIMM interface compatible with standard DDR4 laptop slots, and does ECC work on consumer boards?

Yes, it uses the standard 260-pin DDR4 SO-DIMM form factor. ECC functionality requires a platform that explicitly supports ECC unbuffered memory; on systems without ECC support the module will still operate as non-ECC memory.
