Testbed Configuration and Methodology

We checked out the effects of the memory frequency and timings on the overall system performance in a Core i7-860 based platform. We decided to go with this particular CPU, because on the one hand it supports the widest range of DDR3 memory but at the same time features a relatively democratic price tag. This combination of parameters makes Core i7-860 processor a pretty popular solution these days.

The platform built around this CPU will be tested with DDR3 SDRAM working at 1067, 133 and 1600 MHz. DDR3-800 modules were not included into our today’s test session, because they turned out pretty hard to find in retail: it was a transitional standard that is why this memory has almost completely vanished from the market by now. As for the timings, we tried to cover almost all most popular settings combinations.

During our tests we used the following hardware and software components:

  • CPU: Intel Core i7-860 (Lynnfield, 2.80 GHz, 4 x 256 KBL2, 8 MB L3);
  • Mainboard: ASUS P7P55D Premium (LGA1156, Intel P55 Express);
  • System memory: 2 x 2 GB, DDR3-1600 SDRAM (Kingston HyperX KHX1600C8D3K2/4GX, Corsair Dominator CMD4GX3M2A1600C8);
  • Graphics card: ATI Radeon HD 5870;
  • HDD: Western Digital VelociRaptor WD3000HLFS;
  • PSU: Tagan TG880-U33II (880 W);
  • OS: Microsoft Windows 7 Ultimate x64;
  • Drivers:
    • Intel Chipset Software Installation Utility 9.1.1.1019;
    • ATI Catalyst 9.11 Display Driver.

We would like to thank AMD Russia for providing us with ATI Radeon HD 5870 graphics card for this testbed.
