128GB DDR4 kit for desktops and workstations

This OWC kit delivers 128GB total capacity across eight 16GB UDIMM modules. It is built for desktop PCs and workstation platforms that accept standard 288-pin DDR4 memory. The non-ECC unbuffered design suits mainstream motherboards and NAS systems. Each module runs at the JEDEC-standard 1.2V.

Sustained 2133MHz throughput with CL15 timing

Rated at DDR4 2133 (PC4-17000) with CAS latency 15, the kit maintains its rated speed during extended workloads rather than only in short bursts. Dual-rank 2Rx8 organisation helps keep bandwidth steady when all eight slots are populated. JEDEC compliance ensures the modules operate within specification without manual tuning.

Low-voltage operation keeps thermals simple

At 1.2V the modules draw minimal power, so they add little heat inside the case and do not require active cooling on the memory itself. The black PCBs have no heat spreaders, relying on normal chassis airflow. Silent operation is assured because there are no moving parts on the DIMMs.

Questions about this item

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

Each module operates at 1.2V, the standard DDR4 voltage, so total draw stays within normal desktop limits for eight 16GB sticks.

What must the motherboard provide for these 288-pin UDIMMs to work?

The board needs eight free DDR4 UDIMM slots that support 2133MHz CL15 non-ECC memory at 1.2V.

Will the 2133MHz CL15 modules run stably alongside older DDR4 sticks I keep?

The kit is JEDEC compliant, so the motherboard will typically clock all installed DDR4 to the lowest common speed and latency.
