Two gunmetal grey DDR4 desktop memory modules with low-profile heatsinks

Patriot Memory

Patriot Memory Viper Steel PVS464G320C6K 64GB (2 x 32GB) DDR4 3200 desktop RAM

SKU CH-9DRM-H6Z41 MPN PVS464G320C6K

A 64 GB DDR4 kit with two 32 GB modules running at 3200 MT/s CL16 and 1.35 V for AMD and Intel desktops

  • Total capacity64 GB (2 × 32 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • CAS latencyCL16
  • Memory timings16-20-20-40
  • Rated voltage1.35 V
  • Buffer typeUnbuffered

Capacity 64GB (2 x 32GB)

Speed DDR4 3200 (PC4 25600)

CAS Latency CL16

  • 64 GB capacity from two 32 GB modules for high-density multitasking
  • DDR4 3200 speed rated at PC4 25600 for fast data throughput
  • CL16 CAS latency with 16-20-20-40 timings for responsive performance
  • 35 V operating voltage reduces power draw and heat
  • Intel XMP 2.0 profile enables one-click overclocking on compatible boards

Capacity and audience

This 64GB kit contains two 32GB DDR4 modules built for desktop systems that need large memory pools. It suits content creators, heavy multitaskers and enthusiasts running memory-hungry workloads on AMD or Intel platforms.

Upgrade path

Moving from a 16GB or 32GB kit to this 64GB set is worthwhile when applications regularly exhaust available RAM and force paging to storage. The DDR4 3200 speed with CL16 timing and 1.35V operation matches many modern CPU memory controllers without requiring manual tuning.

Installation notes

The 288-pin unbuffered DIMMs drop into standard desktop slots and expose an Intel XMP 2.0 profile for one-click configuration. Common issues include motherboards defaulting to a lower JEDEC speed until XMP is enabled, and four-slot boards sometimes needing a manual voltage bump to stabilise all four ranks.

Questions about this item

Will this 64 GB kit run at its rated 3200 speed on a motherboard that only supports lower DDR4 speeds?

The modules will operate at the highest speed the motherboard and CPU memory controller allow, which may be below 3200 if the platform is limited.

Is the 1.35 V requirement compatible with standard desktop motherboards?

Yes, 1.35 V is within the normal DDR4 range and supported by virtually all current consumer boards.

Do I need to enable XMP 2.0 in the BIOS to reach the advertised timings?

The kit ships with an Intel XMP 2.0 profile; enabling it in the BIOS will apply the 16-20-20-40 timings at 3200 automatically.
