Some of the Maximus II tweaks are obvious such as the inclusion of the external LCD Poster device that helps you identify problems during start-up. Other changes are less apparent as both the P5Q Deluxe and Maximus II have 16-phase power for the CPU, an Asus EPU-6 power management chip and 2-phase power for the RAM. However P5Q Deluxe has 2-phase power for the Northbridge while Maximus II has 3-phase power.


Maximus II also has two iROG chips that control Extreme Tweaker overclocking features such as CPU Level Up, AI Overclocking, Voltiminder LED, Component Overheat Protection and Loadline Calibration. We’ve seen these features before but the use of the iROG chips is a new approach.


We tested Maximus II with the same hardware we used on the P5Q Deluxe with a Core 2 Quad QX9650, 2GB of Kingston DDR2, a GeForce 8800GT and Windows Vista SP1.


Our first sample of Maximus II was clearly faulty as we were unable to load Windows and the optical USB mouse flashed and was unresponsive. The replacement board was much better so we had a look at the Asus BIOS update page and were surprised at the number of BIOS releases for this relatively new model. Starting at the initial version 0117 Asus has released BIOS 0503, 0603, 0701 and 0802. Version 0503 is a bug fix but the next three versions all relate to memory compatibility which gives an idea of the hassle that Asus faces when it develops a new motherboard.

Choosing settings for overclocking was a vexed matter as our Maximus II behaved itself in almost every respect but there was one notable glitch as it was almost impossible to restart without clearing the CMOS settings. We didn’t get a chance to discuss this with Asus but we have no doubt that it was either a problem that is limited to our sample or is something silly that will be fixed with a BIOS revision.


The overclocking routine was somewhat tedious as we had to try some settings, start Windows, see what happened and then shut down the system. When we started it again the CMOS was clear so we had to enter a new batch of clock and voltage settings from scratch.


On stock settings the Maximus II has a tad more performance than the P5Q Deluxe and draws 5W more power. When it comes to overclocking the P5Q Deluxe had a slight edge as it could run a faster memory speed on a slightly faster front side bus. We expected things to be the other way around but this probably says as much about the intricacies of overclocking the P45 chipset as it does about either the P5Q Deluxe or Maximus II. Either way, it’s too close to be of significance to most.


”’Verdict”’


We expected the Asus Maximus II Formula to be all things to all men and in some ways it does deliver. It has all the toys, a great layout, and it looks the part as well. Nevertheless it doesn’t quite add up to a great whole. In essence, in our review of the Biostar TPower I45
(linkout:https://www.trustedreviews.com/motherboards/review/2008/07/10/Biostar-TPower-I45/p1) we said ‘… it’s hard to see why you’d prefer the Biostar to an Asus P5Q Pro, a P5Q Deluxe or an MSI P45 Diamond’ and, unless you’re desperate for all the toys, you can say exactly the same thing about the Maximus II.
