Asus and overclocking go together like milk and cookies,
so PCSTATS definitely had high hopes for the ASUS P5N-T Deluxe
motherboard. The board was installed with an Intel Core 2 Duo E6750 processor
and a 2GB kit of Corsair DOMINATOR Twin2X2048-8888C4DF memory. If it isn't Corsair, you
ain't getting far!
Before PCSTATS overclocking tests began the DDR2 memory
was configured to run in 800 MHz mode and the Core 2 Duo's clock multiplier set
to 6x in the Asus Extreme Tweaker BIOS. With the nVidia 780i chipset the actual bus speed is listed in the BIOS, so we began at
1333MHz (4 x 333MHz FSB) and jumped to 1400(350), 1440(360), 1500(375),
1540(385), 1580(395), 1600(400), 1640(410), 1680(420), 1760(440), 1800(450),
1840 (460) and finally 1880MHz (470MHz). To achieve this we had to up the nforce
780i northbridge voltage to 1.40V, memory to 1.99V.
To achieve an overclock of 1900 MHz (475MHz) we had to up
northbridge voltage to 1.54V, memory to 2.05V, and that was about as far as we
were able to get with the Asus P5N-T Deluxe motherboard.
The final overclocking results a stable overclock at
1900MHz (4 x 475MHz FSB), with a northbridge voltage of 1.54V, and memory at
2.05V. While this still falls a little shy of overclocks we've seen on some
Intel X38 Express chipsets, it's still a respectable boost to CPU performance.
A Quick Look inside the
BIOS:
nVidia's enthusiast BIOS options are always
easy to work with, and allow for fine control over pretty much every aspect of
the system.
Here you can unlink the Memory Clock from the
FSB, which is great if you're using slower memory that will fall outside of a
specified FSB-to-memory clockspeed ratio.
Here are the max voltages the board supports -
make sure NOT to turn up your memory voltage up to 3.110V yourself or you will
kill the processor
Prelude to
Benchmarks
The details
of how the ASUS P5N-T Deluxe 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 nVidia nForce 780i 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.
