Patriot Viper Elite 5 Ultra RGB DDR5-6400 C32 32GB (2x16GB)

Manufacturer: Patriot

The Patriot Viper Elite 5 Ultra RGB DDR5-6400 is a desktop memory kit designed for systems that support the DDR5 standard. It comes as a two-module set totaling 32GB, with each 16GB stick fitting a standard 288-pin DIMM slot. An integrated heatsink and RGB lighting are both part of the physical design, making it suited for builds where thermals and aesthetics are both considerations.

Running at a tested speed of 6400 MHz with a CAS latency of 32, the kit achieves a true latency of 10 ns at its rated frequency. The secondary timings are set at tRCD 39 and tRP 39, with tRAS at 101. It operates at 1.4V and ships with SPD defaults at 4800 MHz, while also supporting both Intel XMP 3.0 and AMD EXPO profiles for easier overclocking setup. ECC is not supported, and the modules do not use Samsung B-Die. At 44 mm tall, clearance with large CPU coolers should be verified before purchase.

Pros
  • Supports both Intel XMP 3.0 and AMD EXPO profiles, making it compatible with a wide range of modern motherboards for easy frequency configuration
  • Comes as a dual-module 2x16GB kit, enabling dual-channel operation out of the box
  • Tested speed of 6400 MHz with a true latency of 10 ns reflects a well-balanced frequency-to-latency ratio for DDR5
  • Integrated heatsink helps manage heat during sustained operation
  • RGB lighting is included for builds where visual customization matters
Cons
  • CL32 primary timings are relatively loose for DDR5 memory running at this frequency
  • At 44 mm tall, the modules may cause clearance issues with larger CPU coolers
  • Does not use Samsung B-Die, which some users specifically seek out for overclocking headroom
  • ECC memory is not supported, ruling it out for workloads or platforms that require error-correcting memory
  • SPD speed defaults to 4800 MHz, requiring XMP or EXPO profile activation to reach the rated 6400 MHz
Who is this for?

This kit is a solid fit for enthusiasts building or upgrading a DDR5-capable desktop system who want to push beyond default JEDEC speeds without manual tuning — the inclusion of both Intel XMP 3.0 and AMD EXPO profiles means compatible motherboards can apply the 6400 MHz configuration automatically. It also suits users who care about the visual side of their build, since RGB lighting and an integrated heatsink are both part of the package. The 2x16GB dual-channel setup makes it practical for general high-performance desktop workloads where 32GB of total capacity is a reasonable target.

Who is this NOT for?

This kit is not a good match for users who need ECC memory support, such as those running workstation or server platforms that require error correction for data integrity. It is also unsuitable for anyone with a large CPU cooler that has tight clearance constraints, given the 44 mm module height. Additionally, users specifically seeking Samsung B-Die chips for maximum manual overclocking potential will not find that here, as these modules do not use that memory die.

Performance:

tRCD timing 39
tRP timing 39

This kit operates on the DDR5 standard and runs at a tested speed of 6400 MHz, with SPD defaults set at 4800 MHz for out-of-the-box compatibility. The primary timings are configured at CL32, tRCD 39, tRP 39, and tRAS 101, which translate to a true latency of 10 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 ships as a 2 x 16GB configuration, giving a total of 32GB across two modules, each using a standard 288-pin DIMM form factor. The modules run at 1.4V and stand 44 mm tall, which is worth checking against CPU cooler clearance. Samsung B-Die is not used in these modules.

Features:

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

The modules support both Intel XMP 3.0 and AMD EXPO profiles, allowing straightforward frequency and timing configuration through compatible motherboard settings. An integrated heatsink is included, and the modules feature RGB lighting. ECC memory is not supported.

Final Verdict

The Patriot Viper Elite 5 Ultra RGB DDR5-6400 is a straightforward DDR5 desktop kit aimed at users who want a plug-and-play path to 6400 MHz without the complexity of manual timing adjustments, thanks to its dual Intel XMP 3.0 and AMD EXPO profile support. The 2x16GB configuration covers a practical capacity range for modern desktop workloads, and the combination of an integrated heatsink and RGB lighting rounds out the package for builds where aesthetics matter. Its looser CL32 timings and lack of ECC support do narrow the audience somewhat, but for a DDR5-capable consumer desktop build where ease of setup and visual customization are priorities, it delivers a coherent and well-defined feature set.
