Biostar has worked wonders for us recently in terms of overclocking, be it videocard with voltage tuning, or its mainstream motherboards. The TP35D2-A7 motherboard will be equipped with an Intel Core 2 Duo E6750 processor as well as a 2GB set of Corsair's DOMINATOR Twin2X2048-8888C4DF memory in this PCSTATS test. Before overclocking began, the CPU clock multiplier was reduced to 6x and the DDR2 memory set to run at 667 MHz.
Starting at 333 MHz FSB, the clock speed of the Biostar TP35D2-A7 motherboard was increased in 5 MHz steps. As with all the other Intel P35 Express motherboards, the Biostar TP35D2-A7 reached 400 MHz FSB without breaking sweat. Continuing from there, at 455 MHz the Northbridge required a bit of a voltage increase to 1.4V to keep things stable.
Other than that, it was smooth sailing until the
TP35D2-A7 hit a road block at 480 MHz. Any speed higher than
this and the system was unstable when running benchmarks. After about
half an hour of tweaking I was able to put my years of overclocking to use and
squeeze out an extra few megahertz... to 483 MHz. That was
that. Increasing voltages didn't help, so I suspect the P35 Express
Northbridge chipset was overheating.
An overclocked speed of 483 MHz FSB is pretty good considering the Biostar motherboard retails for just over $100 CDN! If you're looking for a low cost, mainstream P35 Express workstation motherboard, and want to have a bit of fun, the TP35D2-A7 fits the bill!
Inside the BIOS:
There are only the basic memory timing adjustments available for the Biostar TP35D2-A7.
That's alright, this is not a high end overclockers motherboard after all. If you
want more features you can spend more and get a tweakers motherboard.
The TP35D2-A7 motherboard supports FSB speeds between 333 to 700 MHz, in 1 MHz
increments. There are a whole slew of memory speed options and the maximum
CPU voltage can be increased 0.787V. Maximum Northbridge voltage is 1.55V and
DDR2 voltage 2.6V.
Prelude to Benchmarks
The details of how the Biostar TP35D2-A7 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 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.
