OWC 16GB DDR4 3200 CL22 1RX8 UDIMM desktop RAM

16GB DDR4 3200 Desktop Module

This 16GB DDR4 3200 CL22 UDIMM is a single 288-pin unbuffered module built for desktop PCs, workstations and compatible NAS systems. It runs at 1.2V with a CL22 latency and contains no heat spreader or LED lighting. The JEDEC-compliant design makes it a straightforward, warranty-safe memory upgrade for non-ECC platforms.

Sustained-load behaviour at 3200 MHz

Under continuous workloads the module operates at its rated 3200 MHz speed with CL22 timing and 1.2V supply. Without a heat spreader the DRAM relies on case airflow to maintain thermal stability during extended sessions. The unbuffered, non-ECC architecture means data integrity checks are handled by the memory controller rather than the module itself, so sustained throughput depends on the platform's memory subsystem.

DDR4 interface practical limits

The DDR4 interface here tops out at 3200 MHz (PC4-25600) with CL22 latency and 1.2V operation. Backward compatibility lets the module run at 2933, 2666, 2400 or 2133 MHz when the system cannot support the highest speed. Maximum usable capacity and channel population are dictated by the motherboard's memory controller and BIOS, not by the stick itself.
