Tri-channel and 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.

Kingston’s KHX16000D3K3/3GX is a triple-channel kit of three 128M x 64-bit 1GB (1024MB) DDR3-2000 CL9 SDRAM (Synchronous DRAM) memory modules, based on eight 128M x 8-bit DDR3 FBGA components per module. Each module kit supports Intel® XMP (Extreme Memory Profiles). Each module kit has been tested to run at DDR3-2000MHz at a latency timing of 9-9-9 at 1.65V. The SPDs are programmed to JEDEC standard latency DDR3-1333Mhz timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers and requires +1.5V. The JEDEC standard electrical and mechanical specifications are as follows:

Here are the specifications of the Kingston DDR3-2000 Triple Channel:

  • Model: KHX16000D3K3/3GX
  • Module Size: 3GB kit (1GB x 3)
  • Package: 240-pin DIMM
  • DDR3-2000
  • Specs: DDR3 PC3-16000
  • 9-9-9-27 Timings
  • NON-ECC 
  • 1.5V
  • 256MB x 64

it is worth noting that Kingston’s HyperX memory is covered under a lifetime warranty, and also comes with free 24/7 technical support.

Let’s take a closer look at these HyperX modules.
