Capacity and kit layout

This kit delivers 16 GB in two 8 GB modules, giving dual-channel bandwidth on mainstream platforms. The DDR4 3200 rating provides ample headroom for gaming and everyday multitasking without manual tuning.

Speed profile and voltage

Tested at 3200 MHz with CL16 16-18-18-36 timings, the sticks run at 1.35 V out of the box. Intel XMP 2.0 lets the firmware apply the rated profile automatically, otherwise they fall back to the standard JEDEC speed.

Build integration and cooling

The black aluminum heat spreader keeps thermals in check inside compact cases while matching dark-themed builds. Unbuffered non-ECC layout suits consumer desktop boards, leaving all four DIMM slots free for future expansion.

Questions about this item

Will the DDR4 3200 CL16 kit downclock automatically when paired with older DDR4 modules rated at lower speeds?

The modules use Intel XMP 2.0 and a JEDEC default profile; when mixed with slower DDR4, the system typically runs all sticks at the lowest common speed and voltage.

How can I verify the kit is running at the tested 3200 MHz with 16-18-18-36 timings after installation?

Enable the XMP 2.0 profile in the BIOS, then check the reported frequency and timings in the firmware or a tool such as CPU-Z to confirm 3200 MHz and CL16.

Does the box include only the two black 8 GB modules with aluminum heat spreaders, or are extra accessories bundled?

The package contains the two 8 GB DIMMs with black aluminum heat spreaders; no cables, screws or additional software are supplied.
