Patriot Viper Xtreme 5 DDR5-6400 C30 32GB (2x16GB)

Manufacturer: Patriot

The Patriot Viper Xtreme 5 DDR5-6400 C30 is a 32GB dual-channel memory kit consisting of two 16GB modules in a 288-pin DIMM form factor. Designed for DDR5 platforms, it operates at a tested speed of 6400 MHz while maintaining a relatively compact heatsink profile at 44 mm tall, making it a straightforward choice for builds where clearance matters. The kit does not include RGB lighting, keeping the aesthetic understated.

On the technical side, the kit ships with a CAS Latency of 30 alongside tRCD and tRP timings of 40 and a tRAS of 76, translating to a true latency figure of 9.38 ns at its rated speed. The SPD-programmed default speed sits at 4800 MHz, with the full 6400 MHz profile accessible via Intel XMP 3.0. It runs at 1.4V, does not use Samsung B-Die, and lacks ECC support, which is consistent with standard consumer desktop memory configurations.

Pros
  • Runs at a tested speed of 6400 MHz with XMP 3.0, allowing straightforward profile activation on compatible platforms
  • True latency of 9.38 ns reflects a well-balanced relationship between clock speed and CAS Latency 30 timings
  • Includes an integrated heatsink for thermal management without adding RGB lighting, keeping the build clean and distraction-free
  • Low-profile height of 44 mm reduces the risk of clearance conflicts with large CPU coolers
  • Comes in a dual-channel 2x16GB configuration, which is suitable for most mainstream desktop workloads
Cons
  • Does not support AMD EXPO, limiting native one-click overclocking to Intel XMP-compatible platforms only
  • SPD default speed is 4800 MHz, meaning full 6400 MHz performance requires manual XMP activation in BIOS
  • Does not use Samsung B-Die, which some enthusiasts specifically seek out for manual overclocking headroom
  • ECC is not supported, making it unsuitable for workloads that require memory error correction
Who is this for?

This kit is well-suited for users building or upgrading mainstream Intel desktop systems that support Intel XMP 3.0, as the 6400 MHz profile can be enabled with a single BIOS toggle. The dual-channel 2x16GB configuration covers the memory needs of most everyday computing, content consumption, and moderate productivity workloads without over-provisioning. The integrated heatsink and 44 mm height also make it a practical fit for mid-tower builds where CPU cooler clearance is a consideration but RGB aesthetics are not a priority.

Who is this NOT for?

This kit is not a good fit for users on AMD platforms that rely exclusively on EXPO profiles, since only Intel XMP 3.0 is supported and one-click speed activation would not be available. It is equally unsuitable for server, workstation, or any reliability-critical environment, as ECC is not supported and memory error correction cannot be enabled. Users who specifically target aggressive manual overclocking beyond rated speeds may also find the absence of Samsung B-Die a limiting factor, as that chip configuration is commonly associated with extended manual tuning headroom.

Performance:

true latency 9.38 ns
memory speed (Tested Speed) 6400
memory speed (SPD) 4800 MHz
DDR memory version 5
CAS Latency (CL) 30
tRAS timing 76
tRCD timing 40
tRP timing 40

This kit operates as DDR5 memory with a tested speed of 6400 MHz, while its SPD-programmed default sits at 4800 MHz for out-of-the-box compatibility. The primary timing configuration consists of a CAS Latency of 30, with tRCD and tRP both set to 40 and a tRAS of 76, resulting in a true latency of 9.38 ns at the rated frequency.

General info:

form factor 288-pin DIMM
memory size (total) 2 x 16GB
has Samsung B-Die ✕
voltage 1.4V
height 44 mm
memory size 16GB

The kit uses a standard 288-pin DIMM form factor and consists of two 16GB modules for a combined total of 32GB. Each module operates at 1.4V and stands 44 mm tall, which is a relatively low-profile height for a heatspreader-equipped DDR5 kit. The modules do not use Samsung B-Die.

Features:

Intel XMP / AMD EXPO Intel XMP 3.0
Supports ECC memory ✕
Has an integrated heatsink ✓
has RGB lighting ✕

The kit supports Intel XMP 3.0 for straightforward overclocking profile activation and comes equipped with an integrated heatsink for thermal management. It does not include RGB lighting, giving it a clean, understated appearance. ECC memory is not supported, which is consistent with standard consumer desktop memory.

Final Verdict

The Patriot Viper Xtreme 5 DDR5-6400 C30 32GB sits in a clear lane: a capable, no-frills DDR5 kit aimed at Intel platform users who want meaningful speed gains over base SPD frequencies without the complexity of manual tuning. Its 6400 MHz XMP 3.0 profile paired with a true latency of 9.38 ns reflects a thoughtful balance between clock speed and timings, and the 2x16GB dual-channel configuration covers the demands of mainstream desktop use comfortably. The absence of RGB, the low 44 mm heatspreader, and the lack of ECC or AMD EXPO support all point to a product with a specific, well-defined audience — and for that audience, it delivers exactly what it sets out to do.
