Viper 3 16 GB DDR3 Kit

This Patriot Viper 3 kit provides 16 GB of desktop memory as two 8 GB modules. It uses DDR3 technology running at 1600 MT/s with a CAS latency of CL9. The unbuffered DIMMs operate at a standard 1.50 V and are designed for Intel and AMD platforms that support DDR3.

CL9 Timing at 1600 MT/s

The decisive specification is the 9-9-9-24 timing at DDR3 1600 (PC3 12800). This CL9 latency determines the kit's responsiveness in latency-sensitive workloads. Buyers must verify their motherboard and CPU officially support DDR3 1600 at this timing before purchasing.

240-Pin Unbuffered DIMMs with Heat Spreaders

Each module fits a standard 240-pin DDR3 slot and requires no manual voltage adjustment thanks to plug-and-play operation. The black heat spreaders dissipate heat to maintain stability during extended use. The kit frees up two additional memory slots on typical four-slot boards for future expansion.

Questions about this item

What does the DDR3 1600 CL9 rating mean for real-world desktop performance?

The kit runs at 1600 MT/s with 9-9-9-24 timings at 1.50 V, giving low latency and high throughput for DDR3 platforms.

How does the PC3 12800 designation limit bandwidth on a DDR3 motherboard?

PC3 12800 is the JEDEC peak transfer rate for DDR3 1600; the board's memory controller cannot exceed that ceiling.

Will the black heat-spreader modules fit a standard 240-pin DDR3 slot without clearance issues?

Each DIMM uses the standard 240-pin DDR3 form factor with a black heat spreader; it fits any desktop DDR3 slot with normal CPU-cooler clearance.
