Dual-channel DDR4 3200 kit

This 16 GB kit contains two 8 GB unbuffered DIMMs rated for DDR4 3200 at CL22 and 1.2 V. The modules are standard UDIMMs built for desktop motherboards that accept DDR4 memory. They arrive as a matched pair to enable dual-channel operation on compatible platforms.

Everyday desktop builds

The kit suits general-purpose PCs, office workstations and entry-level gaming rigs that run at stock JEDEC speeds. Systems requiring ECC error correction, registered modules or lower CAS latency should select different memory.

CL22 latency at 3200 MT/s

The primary timing is CL22, which determines how quickly the memory responds to read commands at the rated 3200 MT/s data rate. This figure is the key specification for deciding whether the kit meets your platform's timing requirements.

Questions about this item

Does the 1.2 V voltage keep heat low when the 3200 kit runs all day?

The modules operate at 1.2 V, the standard DDR4 voltage, so power draw and heat stay at typical levels for continuous desktop use.

What motherboard slots are required for the 2 x 8 GB UDIMM kit?

Two standard DDR4 DIMM slots on a desktop board that supports unbuffered non‑ECC memory.

Will the CL22 timing work with older DDR4 modules already installed?

The system will run all modules at the slowest common speed and highest latency, so mixing with older DDR4 is functional but may lower overall performance.
