Tri-Channel & Specifications

Since the memory controller is directly connected to the processor (and no FSB limits) on the LGA1366 Core i7 chips, bandwidth utilization also takes a huge leap as well. The memory controller can handle 612GB/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 multiples of 3GB, and in the case of today’s HyperX modules, 12GB total..

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.

Kingston’s KHX1600C9D3K6/12GX features the following (from Kingston):

"HyperX DDR3 memory; the latest generation of DDR memory technology. Like all Kingston HyperX products, DDR3 modules are specifically engineered and designed to meet the rigorous requirements of PC enthusiasts. DDR3 memory offers faster speeds, lower latencies, higher data bandwidths and lower power consumption than DDR2. HyperX DDR3 modules are also available in triple-channel memory kits. "

  • Model: KHX1600C9D3K6/12GX/4GX
  • Module Size: 12GB kit (2GB x 6)
  • Package: 240-pin DIMM
  • DDR3-1600 (PC3-128000)
  • 9-9-9 Timings
  • 1.65V
  • Lifetime Warranty

It is worth noting that Kingston’s memory modules are covered under a lifetime warranty.

Let’s take a closer look at these sticks.
