Conclusion
The tests we have performed over the ASUS P4P800-E Deluxe mainboard confirm that this product is a worthy replacement of the P4P800 Deluxe, which has been considered among the best i865PE-based products for over a year. The new version is an improvement on, rather than an overhaul of the previous one, but new features help it in meeting the current demands of computer users. Particularly, the P4P800-E Deluxe supports up to four SerialATA hard disk drives and boasts a unique eight-channel audio subsystem.
The ASUS P4P800-E Deluxe also inherited some of the queer points of its predecessor, especially as concerns configuring the memory subsystem for the maximum performance. The PCB design is worse compared to the P4P800 Deluxe, although not seriously.
Like its predecessor, the P4P800-E Deluxe has high overclocking potential and offers enough tools to actualize this potential. Its stability with the most powerful processors gives no cause for blame. This mainboard surely makes a good overclocking platform.
Overall, if you are searching for a not-very-expensive mainboard for your Socket 478 processor, the ASUS P4P800-E Deluxe may suit you. At the same time, paying more money for an i875P-based board you avoid the above-mentioned configuration troubles.
Highs:
- High stability;
- Rich CPU overclocking opportunities;
- Original technologies and software: Q-Fan and AI technologies;
- Eight-channel audio;
- Rich accessories and reasonable price;
- If you meet certain conditions, you get the performance of i875-based mainboards.
Lows:
- Certain flaws in the PCB design;
- High demands on the quality of the memory modules.
