16GB DDR4 3200 UDIMM

This Samsung module delivers 16GB of DDR4 memory at 3200 MT/s with a CL22 latency. It operates at the standard 1.20V and uses an unbuffered 288-pin UDIMM form factor. The green PCB carries sixteen chips in a 1Rx8 layout without a heat spreader or lighting.

Suits standard desktop upgrades.

The stick fits mainstream consumer motherboards that accept non-ECC unbuffered DDR4 DIMMs. It will not work in servers or workstations that require registered or error-correcting memory. Systems limited to lower DDR4 speeds will run the module at the highest supported rate.

Simple press-in install; watch for key alignment

Installation requires aligning the notch with the slot key and pressing firmly until the retention clips click. The most common issue is the module not seating fully, which prevents the system from posting. Ensure the motherboard firmware is current if the rated speed does not appear automatically.

Questions about this item

Does this 288-pin UDIMM require a motherboard with DDR4 slots?

Yes, the module uses the standard 288-pin DDR4 UDIMM form factor and 1.20V operation, so it fits any desktop board with DDR4 DIMM slots.

Will this 3200 CL22 stick run at its rated speed if I keep my older DDR4 modules installed?

The system will typically clock all modules to the speed of the slowest installed kit; this stick is rated for 3200 at CL22 and 1.20V.

How can I confirm the module is running at 3200 with CL22 timings after installation?

Check the memory tab in CPU-Z or your BIOS/UEFI main screen; it should report 3200 MT/s and CAS latency 22 for this 16GB module.
