Asus P5Q Deluxe Review

» Discuss this article (9)


The performance in the scientific benchmarks showed that the P45 chipset has some room to grow, exceeding the performance of the X48-based board in this comparison in just 13 out of 35 tests. In the video testing, the P45-based P5Q Deluxe showed some potential, and either beat the X48-based board or tied its performance in 23 out of 32 tests run. The flip-side to this comparison is that while it was beaten in many of the scientific benchmarks, the differential in the scores would not be "felt" in the real world. How many people will feel differences this small? Not many, if any at all. Since this chipset is new, the initial offerings will need the few odd BIOS updates to get things just right. The early revision of the BIOS that shipped with the P5Q Deluxe was the 0204 release. I had some "no boot" issues when the voltages were set manually with this BIOS. The 0506 BIOS cured this problem enough to enable my trusty Q9450 to reach stability at 474MHz x 8.

This just happens to be the highest stable overclock I have gotten to date with this particular CPU. While only 4 MHz faster, I was able to boot this chip at up to 500 FSB. Only time and ironing out the motherboard further could make this a reality. The overclocked performance scaled nicely as the clock speeds were increased, making one fast combo. Overclocking really could not be easier with the P5Q Deluxe. Basically set the timings, adjust the Vcore and memory voltage to what they need, and overclock away. The potential is there if you spend the time to go after it. The BIOS and performance can only get better from here, and as this platform matures, I expect to see big things from it.

The Green features of the P5Q Deluxe make energy savings a reality. The system used less energy when the EPU-6 Engine's settings were set to provide maximum savings. While under load, running the [email protected] SMP client and playing Bioshock, I had no performance issues or lockups caused by a lack of power. The savings generated by the EPU and the EPU-6 Engine are determined by the way you allow the system to work. In the energy conscious world we live in, each little bit of energy savings puts those dollars back into our pockets. We buy new energy efficient appliances for our homes, why not do the same for the toys as well? The Asus P5Q Deluxe has plenty of features, and has performance that will only get better. With an attractive price tag of around $200, the price to performance ratio is much better than some of the $400+ boards on the market right now. With this board you can't go wrong.
