BIOS Revision: AMI 0601
Board Revision: 1.01G, 1.02G

ASUS is replacing the P5B (non-deluxe) with the P5B-E. The improvements in the board have centered around better performance and overclocking capabilities. ASUS has improved the BIOS while upgrading or adding additional capacitors on the board. Our opinion is that they have succeeded based upon our test results. The current motherboard that is shipping is a 1.01G revision with either the C1 or C2 P965 stepping. As we witnessed in an earlier article there is not a real difference in performance between the two chipsets.

The current P5B-E 1.01G is very well optioned and sells for around US $160. ASUS will be launching a new revision of the motherboard oriented to the enthusiast crowd in the near future and it sports a new PLL controller that allows up to 1.7V for the MCH and 2.45V for the memory. The current 1.01G board does not offer voltage selections for the MCH and memory is limited to 2.10V. The board revision is 1.02G and we do not know if the name will change at this time or not. However, this should not deter the majority of users from considering the 1.01G motherboard as there is no difference in the performance of the boards except in overclocking when utilizing mid to lower range memory modules that require additional voltage.


ASUS supports their AI Suite of utilities with the P5B-E that include AI N.O.S., AI Gear, AI Nap, AI Booster, and Q-Fan applications. ASUS AI Gear allows for four different fixed settings ranging from maximum performance to maximum power saving. ASUS AI Nap is a power savings utility and Q-Fan controls the CPU and chassis fans. AI Booster allows you to overclock the CPU to a certain level without rebooting to the BIOS. AI N.O.S. determines the load on the system and automatically overclocks the system up to 20%.

We found when setting the AI N.O.S. setting to auto that the system would boot our E6300 at 7x266 with the memory set at DDR2-800 with timings of 5-5-5-15. Once in XP and stressing the system with game play or 3DMark06 it would automatically raise the FSB to 275 with the memory at DDR2-824. If we set the AI N.O.S. from Auto to Sensitive then we could predetermine the percentage of overclock capability with the Turbo setting up to 20%. At the 20% setting the system would lock up due to our memory running at DDR2-958, something not possible with our GEIL DDR2-800 being limited to 2.1V. The FSB setting was 7x319 with memory timings at 5-5-5-18.

Once we backed down to a 15% overclock setting then the system would operate normally. This resulted in a 7x306 FSB with the memory speed at DDR2-920 with timings of 5-5-5-18. We found this to be strange as the system would operate with the memory set manually to 4-4-4-12 at DDR2-980 in our overclock tests. Overall, we still suggest you manually adjust the BIOS for optimum settings with your components.

    Oh, trust me, Gary tested with a LOT of RAM types and manufacturers. However, for the *benchmarks* he settled on one specific set of DIMMs. I think he's trying to put together some information on how the various boards worked with other RAM (see above comment from Gary). Cheers!

    LOL...I think its more like: "What the hell were the Abit engineers thinking?!"



    Based on your experiences, do you know if the Analog Devices AD1988A HD Audio Codec works in Linux? I wouldn't mind going for the ASUS P5B-E at the end of the year.

    And finally, is the rev 1.02G mobo available now? Or in a few months time?

    The 1.09 ADI AD1988A drivers worked fine in SUSE 10.1. Realtek has better support at this time but ADI seems to be catching up. Believe it or not, but we booted every board with SUSE 10.1 just to make sure they went to the desktop. We might even do a once in a while look at Linux down the road.

    what is the range of overclocking possible with pc6400 ram?
    without dividers? with dividers?
  • Gary Key - Saturday, October 21, 2006 - link

    Good question, depends on the PC2-6400 RAM. We are working on something right now to answer your question with a few different modules.
  • xsilver - Sunday, October 22, 2006 - link

    probably something standard like corsair VS or something priced very similar if there is better performance elsewhere
  • xsilver - Sunday, October 22, 2006 - link

    also I would assume that 1gig vs. 2gig makes no difference but if it does, it would be good to know.

    Excellent review Gary. I also look forward for the round 2 and also for a 975/ATI/Nvidia reviews.

    Please try to mention the Vmch used for the overclocking results, as this says a lot about the motherboads also.
  • Gary Key - Saturday, October 21, 2006 - link

    I am setting up a overclocking settings table and will try to show some additional results with different memory types that we used in testing. I have no idea when this will be finished. ;-)

    This article is terrific-- now I just need to read the high-end part and I can finally put together a Core 2 Duo system.

    Will the DS4 be included in the high-end guide? I don't want a DQ-6 because the copper backplate under the processor socket would prevent installation of a Scythe Ninja heatsink.

    Are the AHCI issues going to stay the way they are, with needing to load the drivers from a floppy disk during Windows install, or are there any P965 boards that don't require "an engineering degree and a day off" as you guys said?
