Two black DDR3 memory modules with red heatspreaders

Patriot Memory

Patriot Memory Viper 3 DDR3 8GB Kit 1866MHz CL10 Black Mamba

SKU CH-NSAZ-H83H5

DDR3 8 GB kit with two 4 GB modules running at 1866 MHz and CL10 timings

  • 8 GB dual-channel kit boosts multitasking headroom
  • 1866 MHz DDR3 speed accelerates data throughput
  • CL10 10-11-10-30 timings sharpen response latency
  • XMP 1.3 profile enables one-click overclock setup
  • Black Mamba heatspreader improves thermal dissipation

Viper 3 DDR3 8GB Kit

This Patriot Memory kit delivers 8 GB of DDR3 memory in a matched pair of 4 GB modules. It runs at 1866 MHz with CL10 latency and operates at 1.5 V using standard 240-pin UDIMM slots. The Black Mamba heat spreader helps manage thermals during sustained workloads.

Suited for DDR3 platform upgrades

Builders restoring or upgrading older Intel 6 and 7 Series or AMD 9 and FM Series systems will find the rated speed and timings a direct fit. Users who require ECC error correction or capacities beyond 8 GB per kit cannot use this non-ECC dual-channel package.

1866 MHz CL10 1.5 V DDR3 spec

The decisive specification is the 1866 MHz data rate combined with 10-11-10-30 timings at 1.5 V. If your motherboard and CPU memory controller support this exact DDR3 speed grade, the kit will operate at its rated XMP 1.3 profile without manual tuning.

Questions about this item

How does the 10-11-10-30 timing affect sustained bandwidth?

The CL10 primary latency and 10-11-10-30 secondary timings set the access delay for each column and row operation, defining the steady-state throughput ceiling at 1866 MHz.

What heat output should I expect from the 1.5 V modules during all-day loads?

Operating at the standard DDR3 1.5 V, the Black Mamba kit produces typical DDR3 thermal output; the black aluminium heatspreader dissipates it without active cooling.

Which motherboard slot and firmware feature must my board provide for this 240-pin kit to run at 1866 MHz?

A 240-pin DDR3 UDIMM slot and BIOS support for XMP 1.3 are required to enable the rated 1866 MHz speed automatically.
