Viper 3 8GB DDR3 1600 Kit

This Patriot Viper 3 kit provides 8GB of desktop memory as two 4GB unbuffered DIMMs. The modules run at DDR3 1600 with a PC3 12800 rating and operate at 1.50V. A black heat spreader is fitted to each stick for thermal management.

Dual-channel upgrade for DDR3 systems

The 240-pin dual-channel kit suits older Intel and AMD platforms that support DDR3 1600 and XMP 1.3 profiles. Builders needing ECC, registered modules, or capacities beyond 8GB should choose a different kit.

CL9 9-9-9-24 timing at 1.50V

The specified CAS latency of CL9 and timings of 9-9-9-24 define the kit's responsiveness at the rated voltage. Verify that the motherboard can run DDR3 1600 at these timings before purchase.

Questions about this item

Will this 1.50V Viper 3 kit run alongside the DDR3 modules already in my system?

The kit operates at 1.50V with CL9 9-9-9-24 timings at 1600MHz; mixing modules of different voltages or timings can prevent the system from booting or force all sticks to run at the slowest common settings.

Does this dual-channel kit support XMP 1.3 so I can verify it is running at its rated 1600MHz speed?

Yes, the modules are XMP 1.3 ready; enable the profile in the BIOS and then confirm the memory is running at DDR3 1600 (PC3 12800) with CL9 timings using CPU-Z or the BIOS memory information screen.

My motherboard has four 240-pin slots — do I need to populate specific slots for this 2 x 4GB kit to run in dual-channel mode?

Install the two modules in the same-coloured slots (usually slots 1 and 3 or 2 and 4) as indicated in the motherboard manual; the BIOS will then report dual-channel operation and 8GB total capacity.
