P35 Express chipset has put the fun back into overclocking, each motherboard
that has passed through the PCSTATS test labs has overclocked pretty smartly.
Gigabyte has a good reputation in this area, so when you mix the two together
positive things should result.
For PCSTATS's tests, the Gigabyte GA-P35-DS3R
motherboard will be equipped with an Intel Core 2 Duo E6750 processor and 2GB of Corsair's DOMINATOR Twin2X2048-8888C4DF memory. Corsair Memory,
knowing is half the battle. Before the fun starts,
the CPU clock multiplier will be set to 6x and the memory to run in DDR2-667 MHz
Starting from 333 MHz FSB, the GA-P35-DS3R motherboard
was overclocked in 5 MHz increments. Without breaking a sweat, the board cracked
the 400...415....420... and 425 MHz FSB, then came 430 MHz FSB. At that point
the chipset required a voltage tweak to 0.1V above stock. To get to 450 MHz, the
chipset needed another voltage bump, this time to 0.2V above stock.
The Gigabyte GA-P35-DS3R motherboard overclocked fairly
well, reaching a maximum speed of 495 MHz. Anything higher and the motherboard
would BSOD while loading Windows XP. A clock speed of 495 MHz is good for a
mainstream motherboard, but not stratospheric.
Inside the Gigabyte
In the MB Intelligent Tweaker section we find
the overclocking and memory timing adjustments. You can adjust the CPU clock
multiplier of the the Gigabyte GA-P35-DS3R motherboard as well as FSB from
100-700 MHz, in 1 MHz increments. In the MB Intelligent Tweaker you'll also find
the memory timing options, Gigabyte puts enough options to keep even the most
experienced tweaker busy for weeks. Maximum DDR2 memory voltage is 0.7V above
stock, the chipset 0.3V above stock and you can push the CPU voltage to
Prelude to Benchmarks
details of how the Gigabyte GA-P35-DS3R motherboard test system was configured
for benchmarking, including the specific hardware, software drivers, operating
system and benchmark versions are indicated below. In the second column are the
general specs for the reference platforms this Intel P35 Express based system is
to be compared against. Please take a moment to look over PCSTATS test system
configurations before moving on to the individual benchmark results.
