The Intel Core i7 Test System

All testing was done on a fresh install of Windows Vista Ultimate 64-bit with Service Pack 1 installed. All benchmarks were completed on the desktop with no other software programs running. All of the modules were run in triple-channel mode. The pair of Radeon HD 4870 X2 video cards were run in CrossFireX mode with 8.11 CATALYST drivers and the ASUS P6T Deluxe motherboard was run using BIOS 0904.  The QPI on the processor was left default at 133MHz; Turbo mode was disabled.

Memory Speeds and Timings Tested:

  • 1066MHz – 7-7-7-20 1T @ 1.60V
  • 1333MHz – 9-9-9-24 1T @ 1.60V
  • 1600MHz – 8-8-8-24 1T @ 1.60V

  • 1866MHz – 8-8-8-24 1T @ 1.60V




    The memory kit that was used is a triple-channel kit that contains three 1GB memory modules. The 3GB Kingston HyperX 2GHz kit was able to run all the above clock frequencies and timings with no problems at all, so it was the kit that was used for testing.
