Re-Thinking HR: What Every CIO Needs to Know About Tomorrow's Workforce
The P5Q Deluxe motherboard from Asustek is full of features and innovation that could make it the dream board for many system builders.
We tested the P5Q by installing an Intel Core 2 Quad Q9550 (45-nm, 12MB Level 2 cache, 8.5x1,333MHz; 2.83GHz) and then tried the motherboard out with various RAM configurations. First, we tried the system using four 1GB DDR2 800MHz modules from Corsair and experienced no problems whatsoever. We then tested the unit with a pair of 2GB DDR2 1066MHz modules from Crucial Technology and experienced a slight speed increase, with no impact on reliability. We also tested the P5Q with four 1GB 1066MHz modules from Kingston Technology.
With the BIOS DRAM (dynamic RAM) frequency setting configured as Auto, all of the tested RAM performed flawlessly. Once we started changing the DRAM frequency settings to try to overclock the memory, we ran into some problems, such as system lockups or random blue screens.
Although the P5Q does support overclocking of the various components, we would recommend that system builders shy away from any overclocking to avoid any of the problems we encountered by trying to push the components beyond their advertised limits.
All things considered, Asus has put together an excellent board with the P5Q, and most any system builder will be well served by the board's functionality, reliability and support from Asus.
