PCSTATS has had a lot of luck overclocking Intel P35
Express motherboards. We have high hopes for the Gigabyte GA-P35-DS4
motherboard today. As usual the motherboard will be equipped with an Intel Core 2 Duo E6750 processor and 2GB of Corsair's DOMINATOR Twin2X2048-8888C4DF memory. Before the
overclocking begins though the CPU clock multiplier was first set to 6x and the
memory set to run at DDR2-667 MHz mode.
Starting at 333 MHz the FSB was increased in 5 MHz
increments. Thee Gigabyte GA-P35-DS4 had no problems reaching the 400 MHz
mark, though at 430 MHz the motherboard needed a boost in Northbridge
voltage to 0.15V above stock.
The Gigabyte GA-P35-DS4 handled overclocking well,
but showed signs of instability at 465 MHz FSB. The Northbridge
voltage was then increased to 0.25V above stock, and the issue gone. In the
end, PCSTATS was able to overclock the Gigabyte GA-P35-DS4
motherboard to a maximum speed of 515 MHz. To get there the
motherboard chipset voltage had to be raised to 0.375V above stock... which is a
In the MB Intelligent Tweaker section we find
the overclocking and memory timing adjustments. You can change the CPU clock
multiplier and adjust the Gigabyte GA-P35-DS4 motherboard frequency from 333-700
MHz, in 1 MHz increments. You'll find a whole host of memory timing options,
enough to keep hardcore tweakers busy for weeks I'm sure.
The maximum voltage DDR2 can be bumped
to is 1.55V above stock, the Northbridge goes to 0.375V above stock
and the CPU voltage to 2.35V. A word of warning, those voltages are high enough
to burn out hardware. Use caution if you're going to be overclocking.
Prelude to Benchmarks
details of how the Gigabyte GA-P35-DS4 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.
