64GB DDR4 3333 kit for desktop builds

This 64GB kit contains four 16GB modules running at DDR4 3333 with CL16 timings. It targets enthusiasts and professionals who need high capacity for content creation, virtualization or heavy multitasking on Intel DDR4 platforms. The XMP 2.0 profile enables the rated speed with a single BIOS setting.

64GB capacity with 3333 MT/s headroom

Four ranks per channel give ample bandwidth for video editing timelines, large dataset loading and multiple virtual machines. The CL16 16-18-18-36 timings keep latency low at the rated frequency. Workloads that exceed 64GB or demand speeds beyond 3333 MT/s will require a different solution.

Low-profile aluminium heatspreader at 1.35V

Anodized aluminum spreaders and a custom performance PCB move heat away from the ICs during sustained loads. The modules operate at 1.35V, so power draw stays modest and cooling requirements remain low. The reduced height clears most oversized CPU coolers without airflow compromise.

Questions about this item

Will the 1.35 V modules run stably alongside my existing DDR4 sticks that operate at 1.2 V?

The kit runs at 1.35 V; if your current memory uses 1.2 V the motherboard will default all sticks to the lowest common voltage and speed, so you may need to set the faster XMP profile manually in BIOS.

How do I verify the 3333 MT/s CL16 16-18-18-36 timings are active after installation?

Enter the BIOS or use a tool like CPU-Z and confirm the memory frequency reads 3333 MT/s with timings 16-18-18-36 at 1.35 V; enabling the XMP 2.0 profile applies these settings automatically.

Does the box contain four 16 GB modules or do I need to buy extra sticks to reach 64 GB?

The package includes four 16 GB modules for a total of 64 GB; no additional sticks are required.
