32GB DDR4 kit for Intel platforms

This 32GB kit contains two 16GB DDR4 modules rated at 3000 MT/s with CL15 timings of 15-17-17-35. It targets enthusiasts building on Intel 100 through 400 series and X299 platforms who want high-frequency memory without manual tuning.

Low-profile heatspreader runs cool at 1.35V

Anodized aluminum spreaders on each module move heat away from the eight-layer PCB during sustained loads. The 1.35V operating voltage keeps power draw modest and reduces thermal stress on the memory controller in typical desktop workloads.

Intel XMP 2.0 profile applies rated speed

Enabling the single XMP 2.0 profile in BIOS sets 3000 MT/s, CL15 timings and 1.35V without manual entry. The 288-pin unbuffered non-ECC modules install in standard DDR4 slots and carry a lifetime limited warranty from the manufacturer.

Questions about this item

How do I install the 288-pin DDR4 modules and enable the Intel XMP 2.0 profile?

Align the notch on each 288-pin DDR4 module with the motherboard slot key, press down firmly until the retention clips click on both ends, then enter the BIOS and enable the Intel XMP 2.0 profile so the memory runs at the rated 3000 MT/s with CL15-17-17-35 timings at 1.35 V.

What maintenance or replacement will the 32 GB Vengeance LPX kit need over its lifetime?

The anodized aluminum heatspreader and eight-layer PCB require no routine maintenance; keep the case airflow clear of dust so the modules stay cool, and the kit is covered by a lifetime limited warranty if a module ever fails.

What limit appears first when the 2 x 16 GB kit runs sustained workloads at 3000 MT/s?

The primary limit is thermal: the 1.35 V modules rely on the aluminum heatspreader and PCB to dissipate heat, so inadequate case airflow will cause throttling before any electrical or timing constraint is reached.
