Exact-match DDR4 ECC SODIMM kit

This 16GB kit contains two 8GB unbuffered ECC SODIMMs rated at DDR4-2933 with CL21 timing and 1.20V operation. The modules use a 1Rx8 organisation and 260-pin form factor required by the target Supermicro X12SCV-W and X12SCV-LVDS motherboards.

ECC protection for data integrity

On-die error correction detects and corrects single-bit faults before they corrupt files or crash the system. Unbuffered design keeps latency low while the matched rank, voltage and timing let the memory controller initialise at full rated speed without manual adjustment.

Verify motherboard memory rules

Capacity limits, approved population order and installation sequence differ between system models. Consult the Supermicro manual for your exact board to confirm the 16GB total is supported and the two modules are installed in the correct slots.

Questions about this item

Will the 260-pin SODIMM slots or the 1Rx8 memory chips on this kit ever need replacement?

The 260-pin SODIMM modules have no moving parts and the 1Rx8 chips are surface-mounted, so no routine maintenance or replacement is required under normal use.

What limit appears first when the 2933 MHz CL21 ECC modules run continuously at full load?

The CAS latency of CL21 and the fixed 1.20 V operating voltage set the timing and power envelope that the memory controller manages during sustained operation.

How much heat and power do the two 8 GB unbuffered ECC sticks produce when the system runs all day?

Each module operates at 1.20 V without a heat spreader, so total power draw stays low and passive airflow in the chassis is typically sufficient for cooling.
