Patriot Viper Xtreme 5 RGB DDR5-7800 C38 32GB (2x16GB)

Manufacturer: Patriot

The Patriot Viper Xtreme 5 RGB DDR5-7800 is a dual-channel desktop memory kit designed for systems that support the DDR5 standard. Running at a tested speed of 7800 MHz, it targets users who want high-frequency RAM with RGB lighting built into an integrated heatsink. The kit ships as 2x16GB modules, bringing total installed capacity to 32GB in a standard 288-pin DIMM form factor.

On the timing side, the kit operates at CL38-48-48-84 with a voltage of 1.45V, yielding a true latency of approximately 9.74 ns at its rated speed. The SPD default sits at 5600 MHz for out-of-the-box compatibility, while Intel XMP 3.0 profiles unlock the full 7800 MHz frequency. The modules do not use Samsung B-Die and do not support ECC, and each stick measures 44 mm in height, which may be a consideration in builds with taller CPU coolers.

Pros
  • Tested speed of 7800 MHz with Intel XMP 3.0 support allows compatible motherboards to load the rated frequency and timings automatically
  • True latency of 9.74 ns at the rated speed reflects efficient performance for a high-frequency DDR5 kit
  • 32GB total capacity across two 16GB modules suits memory-intensive workloads
  • Integrated heatsink assists with thermal management during sustained operation
  • RGB lighting is built in for users who factor aesthetics into their build
Cons
  • CL38 primary timings are relatively loose for the frequency, which affects absolute latency efficiency
  • Operating voltage of 1.45V is above the DDR5 baseline, which may be a consideration for power-sensitive builds
  • At 44 mm tall, the modules may not fit in systems with low-clearance CPU coolers
  • Does not use Samsung B-Die, which some users specifically seek out for overclocking headroom
  • ECC memory is not supported, ruling out use in workloads or platforms that require error-correcting memory
Who is this for?

This kit suits users building or upgrading a high-frequency DDR5 system who want 7800 MHz throughput unlocked via Intel XMP 3.0 on a compatible motherboard. The 32GB dual-channel configuration makes it a practical choice for memory-intensive tasks such as content creation, large-scale compilation, or heavy multitasking, and the integrated heatsink with RGB lighting appeals to those who prioritize both thermal management and visible aesthetics in an open-case build.

Who is this NOT for?

Users who require ECC memory for error-correcting workloads or server-grade reliability will need to look elsewhere, as this kit does not support that capability. The 1.45V operating voltage and loose CL38 timings at 7800 MHz may also make it a poor fit for those prioritizing minimal power draw or absolute latency efficiency over raw frequency, and the 44 mm module height can be a practical obstacle in builds paired with low-clearance CPU coolers.

Performance:

true latency 9.74 ns
memory speed (Tested Speed) 7800
memory speed (SPD) 5600 MHz
DDR memory version 5
CAS Latency (CL) 38
tRAS timing 84
tRCD timing 48
tRP timing 48

This DDR5 kit has a tested speed of 7800 MHz, while its SPD-programmed default sits at 5600 MHz for broad out-of-the-box compatibility. The primary timings run at CL38-48-48-84 (CAS Latency, tRCD, tRP, and tRAS respectively), and at the rated frequency those figures translate to a true latency of 9.74 ns.

General info:

form factor 288-pin DIMM
memory size (total) 2 x 16GB
has Samsung B-Die ✕
voltage 1.45V
height 44 mm
memory size 16GB

The kit uses the standard 288-pin DIMM form factor and consists of two 16GB modules for a total installed capacity of 32GB. Each module operates at 1.45V and stands 44 mm tall, which is worth noting when pairing with low-clearance CPU coolers. 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 modules include an integrated heatsink and RGB lighting, making thermal management and aesthetics part of the design. Overclocking profiles are handled through Intel XMP 3.0, allowing supported motherboards to load the rated frequency and timings automatically. ECC memory is not supported.

Final Verdict

The Patriot Viper Xtreme 5 RGB DDR5-7800 is a high-frequency DDR5 kit built around a 7800 MHz tested speed with Intel XMP 3.0, offering a straightforward path to above-spec performance on compatible platforms. Its 32GB dual-channel configuration and integrated heatsink make it a practical choice for memory-intensive desktop builds, while the RGB lighting adds visual flexibility for those who care about system aesthetics. That said, the CL38 timings are on the looser side for its frequency tier, the 44 mm module height demands clearance consideration, and the 1.45V operating voltage sits above the DDR5 baseline — factors worth weighing depending on the build's constraints. For users whose priority is raw clock speed over tight timings in an XMP 3.0-ready system, this kit delivers a well-rounded, high-frequency DDR5 option.
