Capacity and audience

This 64GB kit delivers two 32GB DDR4 modules for desktop systems that need a large memory pool. It suits content creators, developers and multitaskers who run memory-heavy workloads. Builders targeting smaller capacities or different DDR generations should look elsewhere.

Speed and timing

The decisive specification is the DDR4 3600 rating with CL18 latency and 18-22-22-42 timings at 1.35V. This combination determines whether the kit matches the motherboard’s supported frequency and timing envelope.

Sustained operation

Anodized aluminum heatspreaders and a custom performance PCB move heat away from the ICs during extended sessions. The design keeps modules cooler under continuous load rather than only in short bursts.

Questions about this item

What real-world speed and latency will I see once this 3600 CL18 kit is installed?

The kit runs at DDR4 3600 with timings of 18-22-22-42 at 1.35 V when the XMP 2.0 profile is enabled in the BIOS.

What does the XMP 2.0 profile actually set on this memory?

XMP 2.0 automatically configures the modules to DDR4 3600, CL18, 18-22-22-42 timings and 1.35 V without manual tuning.

Will these low-profile modules clear my CPU cooler and fit a standard 288-pin slot?

The anodised aluminium heatspreader keeps the modules low-profile, and each stick uses the standard 288-pin DDR4 form factor for desktop motherboards.
