Viper 3 DDR3 1866 Kit

This Patriot Viper 3 kit provides 16GB of DDR3 memory across two 8GB modules rated at 1866 MT/s with CL10 timing. It targets enthusiasts upgrading or maintaining dual-channel desktop platforms that use 240-pin DDR3 slots. The black heat spreader aids thermal management during sustained workloads.

Platform Compatibility Check

Verify that your motherboard supports DDR3 1866 (PC3-15000) operation and can run at the specified 1.50V. Confirm the board has at least two free 240-pin slots and that the CPU memory controller is validated for this speed. The kit is unbuffered and non-ECC, so it requires a consumer desktop platform rather than a server or workstation board.

Build Integration

The dual-channel pair installs directly into matching DIMM slots to enable interleaved bandwidth without manual configuration. Modules operate at standard 1.50V, drawing power from the slot alone. The low-profile heat shield fits beneath most CPU coolers, leaving surrounding headers and expansion cards unobstructed. No extra cables or software are required.

Questions about this item

Will this 16 GB kit work in a motherboard with four DDR3 slots?

Yes, the dual-channel kit installs in the two primary slots; the remaining slots can be populated later with identical modules.

Does the 1.50 V voltage match standard DDR3 desktop requirements?

Yes, 1.50 V is the standard JEDEC voltage for DDR3 desktop memory, so no manual voltage adjustment is needed.

What clearance does the black heat shield need above the DIMM?

The custom heat shield adds modest height; verify your CPU cooler specification to ensure at least a few millimetres of gap.
