Performance Testbed

Now that we have covered practically all aspects of Foxconn Mars mainboard, it is time we analyzed its performance compared with the competing solutions from other mainboard makers. Since Foxconn board came a little late to the market, we will compare it against the Intel P35 based solutions with DDR2 support that have already won the dedicated overclockers’ hearts – Asus P5K Premium and Gigabyte P35-DQ6.

Our test platform was configured as follows:

  • CPU: Intel Core 2 Duo E6850 ((LGA775, 3.0GHz, 1333MHz FSB, 4MB L2, Conroe).
  • Mainboards:
    • ASUS P5K Premium (LGA775, Intel P35, DDR2 SDRAM);
    • Foxconn Mars (LGA775, Intel P35, DDR2 SDRAM);
    • Gigabyte P35-DQ6 (LGA775, Intel P35, DDR2 SDRAM).
  • Memory: Corsair Dominator TWIN2X2048-8888C4DF.
  • Graphics card: OCZ GeForce 8800GTX (PCI-E x16).
  • HDD: Western Digital WD1500AHFD (SATA150).
  • OS: Microsoft Windows Vista x86.

Performance in Nominal Mode

The first series of tests were performed with the processor working at its default speed of 3.0GHz set as 9 x 333MHz. We tried to set the memory frequency in this case at 1066MHz with 4-4-4-12 timings. I would like to stress the word “tried”: although DDR2-1066 is the nominal work mode for the memory bus supported by Intel P35 Express chipset, Foxconn Mars failed to clock DDR2 SDRAM at this frequency. There was no 5:8 FSB:DRAM divider in the BIOS Setup list that’s why we couldn’t get DDR2-1066 supported at 333MHs bus frequency.

So, we had to use the closest divider of 2:3 and reduce the memory frequency to 1000MHz.
