Tri-channel & Specifications

Since the memory controller is now directly connected to the processor (and no FSB limits) on the Core i7 chips, bandwidth utilization will also take a huge leap as well. The memory controller can handle 64GB/s, though only 32GB/s bandwidth is being utilized at DDR3-1333 JEDEC standard. So while the bandwidth increase is already massive over the previous architectures, there’s obviously tonnes more left in the tank here. The last difference is more obvious; the memory controller can use three 64-bit channel for this increased bandwidth, thus resulting in six DIMM slots, so you see modules being currently sold in 3x1GB or 3x2GB configurations.

At this point in time, only Core i7 (Socket 1366, X58 chipset) will take tri-channel RAM. You must then obviously have an X58 motherboard that will have either three or six DIMM slots as mentioned. You do have the option of running dual-channel DDR3 in a tri-channel motherboard, but then you are running below spec and certainly not anywhere near the crazy bandwidth that tri-channel offers. So if you’re in a pinch, you can use your current DDR3 in an X58 motherboard….BUT……there is one significant caution: you absolutely MUST have DDR3 modules that can run at 1.65V or less. This is because Intel has set a maximum voltage limit of 1.65 volts on the memory modules. This is due to the Integrated Memory Controller which is now located on-die in the CPU itself, so if you exceed the 1.65 volts on the memory then you run the very real risk of damaging your lovely i7 CPU. So be forewarned.

Patriot’s PVT36G1600LLK features the following (from Patriot):

Patriot Extreme Performance (EP) Low Latency line is engineered to expand your gaming options. These modules are designed to operate at 1600MHz at 8-8-8-24 timings and is available in 3GB and 6GB kit capacities. Equipped with Patriot ACC (Aluminum Copper Composite) technology, these modules are designed for maximum performance and stability under extreme overclocking conditions. Engineered with quality and Performance in mind, Patriot Extreme Performance line is the ultimate solution for extreme overclockers, gamers, and PC enthusiasts.

Here are the specifications of the Patriot Viper 6GB DDR3-1600 Tri-Channel:

  • Model: Patriot PVT36G1600LLK
  • Module Size: 6GB kit (2GB x 3)
  • DDR3-1600
