Kt3 ultra-aru multiplier prob

I just bought a new MSI kt3 ultra-aru from newegg and a new athlon xp 1900+(1.6ghz) and i unlocked it but the board wont boot with the new multiplier, so i thought the proc was not unlock so i try my old tbird which has already been unlocked and it does not work either, help Plz

Setting any multiplier below 9 would make the system unable to boot. I need to clear CMOS to be able reboot.
Setting the multiplier to 9 or above: no problem.
My CPU is an Athlon 1400 and its L1 bridges are "factory unlocked".
How could I fix this issue?
Many thanks.
Not that this may help, but years ago I had an old Pentium 2 that had its multiplier locked when going above its default, but unlocked when going below its default multiplier.  It came this way from the factory. Pretty good FSB overclocker, btw.... :]   Later I found that Intel had changed this and subsequent P2's came from the factory locked in both directions.
Might it be that the cpu is not as "unlocked" as you've been led to believe?  Just a thought.  A way to prove this one way or the other I think would be to try it in another motherboard.
Well, I don't think this is the same kind of issue because I used this Athlon 1400 with any multiplier on an ABIT KT7A before buying this MSI KT3.

  • KT3 Ultra ARU PC hangs

    Hi there.
    I have a MSI KT3 Ultra ARU motherboard, AMD XP 2600+, 2x 256 MB Apacher DDR 333 and a Radeon 9700 Pro card. Yesterday I changed CPU from Thunderbird 1.4 to XP 2600+. I had some memory problems with one of the apacher modules, but everything worked fine afterwards. I must say my computer including the OS (WinXP Pro) has been realy stable up to now, and I have never seen this kind of a hang before.
    I was burning a CD (in 4x) while watching a .avi file and the computer hangs. It did not hang fully at the start. First hang nero, then some other programs, then startmeny and desktop, and then the mouse. PC speaker was making a constant bip the whole time until I restarted...
    The system booted up, but I was wondering what it could be? I have some feeling it may be a memory problem, and will check that later on, but that will take some time. I hope someone here knows what to doo, and help me solve this problem.
    Everyone where I am from tells me to buy intel becouse they say AMD is not as stable as intel. I dont think intel is bether than AMD, and my old Thunderbird was rockstable even at 1636 MHz, overclocked by multiplier.

    Hi DataFMT,
    Thanks!
    You should see my IRQ's, I tried to get them all on a single one :D
    It doesn't matter if they are shared or not.
    But the trouble is, the APIC does try to seperate them for the CPU's (Yes CPU's) as it's Multi-CPU specification and designed to seperate them in order to let the appropriate CPU handle the IRQ instead of all off them at the same time.
    On a single CPU system this is stupid to use as the CPU needs to respond to every IRQ anyway.
    Microsoft gas gone totaly nuts on this matter and their article about the APIC is as stupid as it can be.
    They are mixing all sorts of (A)Pic's without knowing what they are doing.
    Ever wondered why Multi-CPU systems are so hard to get stable when the need for high-load is there?
    Every system today has multiple PIC (programmable IRQ controller).
    The first old one is called PIC, that one needs to be programmed for every IRQ and has a hard time on IRQ sharing and the OS needs to program it, when you use Standard-PC, that's the one you use.
    Not a good one to use as it slows the system down.
    So far Microsoft is right.
    The next one is the Local-APIC (A=Advanced), this one can share IRQ's without problems and sort of programs itself, ergo, you can't change IRQ's, and there is no need to do so anyway.
    This one is used when you enable ACPI and use ACPI-compliant-system.
    It's fast, stable and very OS/driver friendly.
    Then you have the I/O APIC, in the chipset, that one is the APIC/MPS the BIOS setting controls.
    MS screws up here big time, this one translates the real IRQ's into addresses and feeds them to the CPU PIC or Local-APIC, depend if ACPI is enabled or not.
    This one is a trouble maker, because the translation isn't needed for a single CPU system and not all drivers like it's behavior.
    Another thing is that it needs to buffer a lot, and when driving your system to the limits it can jump IRQ signals because the servicing of them can be a bit behind.
    This looks like the system is faster, but a jump can cause a lot of trouble.
    Good samples of this happening are running too fast/slow system clock in WinNT/2000/XP when you have a heavy load.
    Do a search in google and you see plenty examples.
    Another good example of this is caused by Norton, that can disturb the sound when Apic is used.
    I have discussed with MSI why APIC was turned on by default, they said it was stupid, but the PC-2001 spec requires this....and guess who wrote the spec???? :D
    I have also seen that a lot of other Mobo makers are starting to turn the APIC off by default and let you run with the Local-Apic by default.
    A far better choice if you ask me, but then who asks me??? :P

  • MSI KT3 Ultra ARU & GeForce 3 TI200

    A little prob:
    When I run my GF3 in AGP mode, all my games hang after playing 1 min. Then when I change the "Via Tech CPU to AGP-controller" to "PCI standard PCI to PCI brigde" thereby running my GF3 in PCI-mode everything runs fine. Then I went into "dxdiag" and saw that "Acceleration of AGP-struktur" was not availble. So I was thinking, am I looseing enything by running the GF3 in PCI-mode and is it the MSI or the GF3 that is causeing this problem.
    I have tried all the VIA 4in1 drivers and they did not help.
    My specs:
    MSI KT3 Ultra ARU
    Athlon XP 1900+
    Palite Daytona Geforce 3 TI200
    Windows XP pro

    i have the kt3 ultra with a geforce 3 ti200 and it runs flawless.. i use the det 30.30 drivers. one thing i noticed with geforce 3 cards is if i have my agp apperature set to anything but 128 games will freeze and get all kinds off lock ups. if i were you i would look around this forum for the bios setup guide for the kt3 ultra! and set your bios according to that guide
    if you cant find it here goto http://www.amdmb.com and go to the msi forum there and the set up guide is there
    hopefully that helps!!!!

  • MSI KT3 Ultra-ARU with GeForce 4 Ti 4200

    Umm...
    My PC keep freezing when I play a 3D Game like Warcraft III, GTA 3 or Neverwinter Nigths.
    Sometimes it's freezing after 2 mins, sometimes I can play like a half hour.
    When it's freezed, Windows don't work either so the whole comp is messed up then .. and I have to reboot him.
    I post this here cuz I heard that those new GeForce Cards have some compatibilty probs with mainboards ...

  • MSI KT3 Ultra-ARU

    Can anyway say to me the PCI/AGP dividers of MSI Kt3 ULTRA -ARU?
    Thanx in advance

    The 1/4 dividers has:
    PCI = 1/4*133 = 33mhz
    AGP = 2/4*133 = 66mhz
    The 1/5 dividers has:
    PCI = 1/5*166 = 33mhz
    AGP = 2/5*166 = 66mhz
    The futuristic 1/6 dividers will have:
    PCI = 1/6*200 = 33mhz
    AGP = 2/6*200 = 66mhz
    Your equation "...and the AGP card of 4X = 4(FSB/5)" would yield a result of 4(133/5) =  106mhz for the agp so it is way out of spec.
    Hey man, I've unlockes my athlon xp 1900+, changed multiplier to 10x, fsb to 166 and sisoft sandra 2002 sp1 said that the pci was running at 42 mhz and the agp at 84. MSI KT3 Ultra-ARU, bios 5.5
    Also, I can't run with 12.5/13x, it uses 12 instead.
    Can you help me?

  • MSI KT3 Ultra-ARU video lock-ups

    Hello,
        I have a 3 month old MSI KT3 Ultra-ARU.  I am running Windows XP Professional and I am having a periodic lock-up where the screen will show blinking colored blocks and the system will freeze.  Sometimes just hitting reset will cure the problem.  Other times, hitting reset will create two vertical stripes of colored blocks scrolling down the screen.  I have used the board on two entirely separate systems (One with AMD Athlon 2000+, Gainward GeForce 4200, 512 MB Samsung 2700 DDR, Western Digital Expert HD (tried both IDE #1 and RAID controller) (Other System, Athlon 1800+, a different Gainward Geforce 4200, 256 Crucial 2700 DDR, an older Maxtor hard drive).  In either system, every once in a while, the system will freeze as described above (it has happened in Netscape 7.0, Microsoft Word 2000, America's Army game).  
         I have played around with the bios settings, reformatted hard drives, tried various revisions of the nvidia display drivers, swapped out video cards, etc.  Any ideas?  Do I have a bad board?  Do I need to flash the BIOS?  If the board is bad, what do I need to do to return it?
    Thanks,
    Matt Gumaer

    The second system has a 330 watt enermax power supply.  With the new system I put together, I put virtually the same board (MSI KT3 Ultra 2 with bluetooth and RAID), everything is the same as my first system (except the KT3 Ultra-ARU) and the stability is fine.  So, I'm reasonably confident its not the power supply.

  • KT3 Ultra-ARU not work with ATI 9600pro?

    Hi,
    I have recently(yesterday) bought an ATI 9600pro, to upgrade my old GF2pro. As the title says, I have the KT3 Ultra-ARU(MS-6380E)
    There seems to be lockup problems that involve only certian games and the ATI DVD player. In all instances the lock ups happen when the mouse is moved. With respect to the ATI DVD player, it will lock if the mouse is moved over the video window.
    I have tried a few things but nothing works, so I am posting here to try and see if someone knows something and I will contact ATI in a few hours, or maybe tomorrow.

    For via chipset (kt333 based msi kt3 ultra-aru) i can now obtain full hardware acceleration and 100% stable for c&c generals game by:
    1) download and install latest catalyst 3.7 driver/control panel/samartgart from ati.
    2) disable fast-write in bios..
    3) go to c:programsati technologyati control panel and execute smartgart
    4) enable - pci read/write and agp read.
    5) disable - agp write (default in my case was on causing the problem).
    6) "apply", reboot, then "ok".

    I wish MSI would post something about the new Athlons XP's.  I would think that they should have a few of the processors already.  Every review sight seems to have thier hands on one.  I did see in the bios updates that they posted a BIOS update for the KT3 Ultra-C on 8/26/02 that says it adds support for the XP 2400+
    I have never seen this board anywhere though.  I have seen other motherboard manufactures have BIOS updates for them already.  This is my first time buying an MSI board and I hope that they get on the ball about this or it may be my last MSI board.  I guess I won't start to worry to much until I can actually find a 2400 to buy, but it would be nice to here something from MSI.  If my KT3 Ultra2-R won't support the new processors then I can buy a 2200+ now and end my wait.

  • KT3 Ultra-ARU SB Live! problem when using onboard Promise MBFasttrak 1

    Hello !
    I have one little problem with my motherboard. I know it's a little bit older compared to today's MSI production.. I have a MSI KT3 Ultra-ARU motherboard. I used only VT8233A southbridge's IDE until now, and everything worked perfectly. But now, I bought two Maxtor 80GB disks and placed them to a onboard Promise MBFasttrak 133 Lite (PDC20276) RAID in stripping mode. Everything works, except Soundblaster Live!. The soundcard itself works normally, but when I start to copy some files (and have some MP3's or video's running) the audio gets distorted in rythm with data transfer. I checked IRQs or address spaces, but IDE is on another IRQ than any other device, the same is address space. Had anyone the same experience with this "problem" ? Please let me know...

  • KT3 Ultra ARU Slow HD Transfer Rates

    Hello,
    First, please see my system information at the bottom of this message.
    I have a MSI KT3 Ultra ARU motherboard and have installed a Maxtor ATA133 60GB hard drive with 2 MB cache.  The hard drive is jumpered as Master and is connected all by itself on the IDE1 ribbon cable.  On IDE2 I have a CDRW (Master) and a CD-ROM (Slave).  My other hard drive (WD 120GB ATA100 8 MB cache) is on IDE3 and is set up in RAID 1+0 stripe.
    I recently ran the Sandra file system benchmark on my hard drives with what I think are very discouraging results.  My Maxtor drive on IDE1 scored 32 MB/s and my WD drive on IDE3 came in at 23 MB/s.  Those are some stinky results aren’t they?
    I checked my Device Manager under IDE ATA/ATAPI Controllers and it indicates that for my Primary IDE Channel the current transfer mode for device 0 is Ultra DMA Mode 6.  I don’t know how to check the transfer mode on my IDE3 hard drive.
    Question #1:  Are my 32 MB/s and 23 MB/s results slow for my hardware?
    Question #2:  If these results are slow, how can I increase the transfer rates?
    Please help! 
    Thank you!!!!

    I have a Pentagram Dark 56I modem (Lucent win modem) installed on MSI KT3 Ultra-ARU. Everything is working now except my modem witch does not connect to the internet (only one out of fifty connections is successful). I haven’t got any idea what is wrong and what settings in bios are responsible for the work of internal PCI modem with MSI motherboard.  The modem is 100% efficient (it worked fine during 13 months, latest driver, proper settings, checked on another computers), telephone line too. I tried all bioses 5.1, 5.3, 5.4, 5.6, all PCI slots, Windows 98, 98se, Me, 2000, XP pro, PCI latency patch, another mouse and keyboard. Now I am going to suicide ;( .  Do you have any idea what else can be wrong (I disconnect every peripheries): broken motherboard, memory (1x256 DDR PC2100, checked in all slots) or my Athlon XP 1800+?  ?(

  • Kt3 Ultra-aru Processor Speeds?

    Hi There,
        I'm running the MSI KT3 Ultra-ARU (MS-6380E v1.X) with an AMD Athlon XP 2000, I was just wondering what Athlon XP processor speeds this supports upto, and if possible what changes I might need to make to the Bios, Would I need to flash my board with a new Bios or just go into my Bios and change some settings.
    Thanks for any help, just trying to get ready for Doom 3 and Halflife 2 if they ever appear  
    Cheers,
    Paul.

    But there is no guaranty, that a FSB333 AthlonXP will work. The largest CPU that is allowed from MSI is a 2600+ FSB266.
    But the chance is pretty high, that a FSB333 Athlon will work, though. It did so on mine KT3 Ultra.

    anyone either running a newer processor on this board, or who would know the answer, it would be appreciated....

  • KT3 Ultra ARU - Restricted Voltages?

    I'm running a MSI KT3 Ultra ARU with an Athlon 1700+ tbred. I was trying to adjust the voltage, but the max I can put it at is 1.6V (the default voltage for my chip is 1.5V). Now, I know the board can go higher for sure, because prior to this tbred, I was running a Palomino, and I had the voltage at 1.85V. But now, the max it allows me to select is 1.6V. Is there a way to "unlock" the voltage so I can bump it up past 1.6V?

    This seems to be the #1 complaint for the kt3-ultra series. I'd too like to find a way(without mods) to get the voltage past 1.6 on my tbredA. I heard they may be releasing a new bios(at least for my ultra2) but I doubt it'll affect the voltage adjustments. It'll Probably just have a few bug fixes and barton support.
