OWC 16GB DDR4 3200 ECC UDIMM

This single 16GB DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It is an unbuffered ECC UDIMM designed for workstations, servers and NAS systems that require error-correcting memory. The 288-pin form factor fits standard desktop DIMM slots.

Sustained workload stability with ECC

Error-correcting code detects and corrects single-bit errors during continuous operation, reducing the risk of silent data corruption in long-running tasks. JEDEC-compliant timings at PC4-25600 maintain consistent throughput without relying on overclocking headroom. Backward compatibility with 2133, 2400, 2666 and 2933MHz platforms allows the module to run reliably at the highest speed the host supports.

Plain black PCB with no heat spreader

The module uses a low-profile black circuit board that fits tight clearance around large CPU coolers or in dense server chassis. Absence of a heat spreader keeps the profile slim for multi-DIMM configurations where spacing is minimal. Gold-edge contacts on the 288-pin connector resist oxidation for reliable seating over repeated install cycles.

Perguntas sobre este artigo

How much power does the 1.2 V DDR4 3200 module draw when the system runs all day?

The module operates at the standard DDR4 voltage of 1.2 V, which keeps power draw low during continuous workloads in workstations, servers or NAS units.

What must the motherboard provide for this 288-pin ECC unbuffered DIMM to function?

A DDR4 UDIMM slot that supports ECC operation; the board’s memory controller must be able to use the extra error-correction bits on this 1Rx8 module.

Will the CL22 3200 MHz stick run stably alongside my existing 2133 MHz, 2400 MHz, 2666 MHz or 2933 MHz modules?

Yes — the DIMM is backward compatible with those speeds and will down-clock to match the slowest installed module while maintaining ECC integrity.
