    Hi all my first time here so top of the morning to ye all.

    Bit of a tech dunce so please bare with me.

    Looks like I may have had a corrupt bios sting as m/b on boot still said 1001E and cpuz 1009 beta.

    I flashed to bios 1008 Duel Channel as I could not get some new OCZ PC3200 Platinum to run on my board, although it always has ran OCZ PC3200 basic.

    Something is definitely seriously weird with this “Duel Channel” 1008 bios.

    No matter what I change

    CPU external 133 or 166 Mhz
    CPU frequency x11/x12.5/8.0 =16/auto

    Bios on boot says I have a cpu 1240Mhz….cpuz reports the same and I don’t seem able to get out of the duel channel mode………….any ideas how I can

    I am not a regular bios flash expert so is it possible/advisable to get rid of this “Duel Channel” 1008 and revert to a lower one.

    Any ideas

    Please forgive my inexperience in not understanding Duel Channel boot

    I have now understand this….duh!

    But no matter what setting cpu frequency/external/memory frequency I use XP2600 still shows 1250Mhz on boot

    I give the most likely solution: contact ASUS for a replacement Bios. They will flash it according to your instructions. The board revision does make a difference.

    My board: pcb 1.03, bios 1007. Bios 1007 works for pcb 1.03, 1.04, & 1.06.

    It appears that 1007 was issued after 1008. However, talk to Asus. There can be differences in each version.

    1007 works with dual channel RAM.

    I cannot speak to setting the frequencies / speeds. I go by the spec sheet for the cpu. I let the bios choose the settings (auto spd). If the Bios burst screen identifies the xp2600 correctly, then there is hope bios is not corrupted.

    Hi rf6647 thank you for your reply

    Not sure about 1007 being later than 1008

    Date created on these files show

    1008 16/10/2004 at 11.24.26

    1007 08/10/2003 at 18.10.00

    But I somehow think that the 1008 is the problem as I have never had this fault with my previous bios.

    I will flash the 1007 and post back.

    Sad news, this is the match that I found by using the date
    1010   2004/08/10    [aug. 10.2004]
    The dunderheads neglected to use the "C" prefix as was done
     in the past to signify application to pcb 2.0 & later only 
    Membership is free at Asus. Enter serial number for the board; this creates a record that links useful info to the mobo.

    Yes, it is possible that the screen information may not accurately reflect the file date in the bios flash.

    Your first post captured '1009 beta'. Not a good sign.

    I reverted back to bios 1001E and my XP2600 was recognised immediately, with cpuz saying the same.

    I then flashed to bios 1007 and on boot bios says 1250Mhz processor, the same as it did with bios 1008 and again with cpuz saying 1250 Mhz.

    Changing bios settings 133/166 fsb with multipliers x11/x12.5, memory syn/auto/100% etc my cpu is only recognised as 1250Mhz

    I am confused to say the least

    & what do the other BIOS version bring that you don't have with 1001E ? If it works well for you, stick with it.

    I can not get some ocz platinum ram to work with my m/b, which is why I upgraded the bios to revisions which so say overcame this issue.

    What is the problem with the OCZ Platinum memory ? The system does not boot at all when they are installed or does it display an odd behavior afterwards ?

    Success at last

    After much web searching and a lot of help and advice I was pointed in the direction of trats at the following forum.


    His modified version of 1009 bios flashed fine and recognised my XP2600 on boot and showing 2088Mhz in cpuz

    I still cannot get the ocz ram to work, so its back to good auld Crucial.

    Thanks to all who replied to this thread.
