16GB DDR4 ECC SODIMM for Samsung systems

This 16GB DDR4 2933 ECC SODIMM is built for Samsung servers, workstations and all-in-one PCs that require unbuffered error-correcting memory. It delivers 16GB of capacity in a single 260-pin module rated at PC4-23400 with CL21 latency.

Low-voltage operation without a heat spreader

The module runs at 1.20V and uses Samsung, Micron or Hynix DRAM in a 2Rx8 organisation. With no heat spreader fitted, it relies on system airflow and the low voltage to maintain stable temperatures during typical workloads.

Fits 260-pin SODIMM slots in compatible Samsung

Installation is a straightforward slot-in upgrade for supported Samsung devices. The unbuffered ECC design works with motherboards that accept DDR4 ECC SODIMMs, freeing a second slot for future expansion while keeping the memory subsystem simple.

Questions about this item

How do I install this 260-pin DDR4 ECC SODIMM and what step is often missed?

Align the notch on the module with the slot key, insert at an angle, then press down firmly until both side clips snap shut; the step often missed is fully seating both clips so the ECC module makes complete contact.

What maintenance or replacement will this 16GB 2Rx8 module need later?

No routine maintenance is required; replacement is only necessary if a memory test reports correctable errors that exceed the system threshold or if a DIMM fails completely.

What limit appears first under sustained load with this CL21 1.20V kit?

The thermal limit of the unbuffered Samsung chips typically appears first, causing the memory controller to throttle frequency before voltage or timing constraints are reached.
