KT4 Ultra (MS-6590) Please help me!

After som reading at MSI homepage i noticed that my motherboard suppurted AMD Athlon 3000+ if i flashed the BIOS.
So i did get a brand new AMD Athlon 3000+, flashed the BIOS to ver 1.4. And I changed the Frequency/Voltage to 166, and i was up and running.....for a while. Every time a start a game like FS 2004 or are working in 3-4 different programs the computer like DW, PS and Illustratoer:
1. close down one or two programs, or shuts down the game, without any warning.
2. reboot the computer without any warning.
But if i change the Frequency/Voltage to 133 the system get's stabil.

Question
Why KT4 Ultra (MS-6590) cannot detect my AMD XP 3000+ (FSB 333) CPU properly?
Answer
FSB clock by default is 100, make sure that BIOS setup-->Frequency/Voltage Control-->CPU FSB clock set as 166

KT4 Ultra MS-6590 and XP-Install problems

hi,
yesterday i got my KT4 Ultra (MS-6590) motherboard with XP2700+ and 1x512MB PC333.
I tried to installed on my 80GB HDD (samsung) windows XP Pro.
But i cant. i get often an error when the first files are copied (after CD-boot): " File xxxxx is damaged. istall is stopped"
or i get a blue screen IRQL_NOT_LESS_OR_EQUAL
i deactiveted in Bios EVERYTHING what has to do with caching.
then install runs (i must wait many houres :O ) and after the final reboot i had the welcome screen and after a few minutes a get the system beep and a reboot.
why?
why can i not install my XP like other people..
what is the problem?
i dont made a bios update yet.
Please help... THANKS

Thank you for you help
i searched on the german MSI Homepage http://www.msi-computer.de for the BIOS update (i am german ) and i only find version 1.2.
should it work with this version? or is the bug fixed only in 1.3?
where can i download version 1.3 (compatible with german boards too or is there no different?)
i have a award bios and on the official HP seems that there are only AMI Bios.
Version 1.2 (AMI)

KT4 Ultra MS-6590 - Win XP Home boots with 2GB DDR333 installed but not 3GB

Spec...
KT4 Ultra MS-6590
AMD Athlon XP 3000+ (FSB set to 166MHz in BIOS)
BIOS MS-6590v1.4
Win XP Home 2002, SP3
Problem...
Previously, had 768MB RAM installed, and XP strangely identified CPU as a 2200+.
Recently upgraded the RAM to 3GB DDR333 (3 sticks of 1GB 184-pin unbuff DIMM 128MX64 DDR PC2700), and changed BIOS settings for CPU and DRAM.
In the DOS boot screen, Win XP progress indicator fills completely from left to right, then stops with a half-blinking cursor in the top left of the screen.
Removed 1GB stick and Win XP successfully loaded, also now recognising the Athlon XP 3000+, and running a heck of a lot faster.
Tried adding the /3GB switch to the boot.ini file, which didn't do anything, and after reading more forum advice, guessed this might be irrelevant. I don't think this is a 4GT and PAE issue, as I'm not trying to install above 4GB (if I've correctly understood).
Also, forum advice (various sites) conflicts on whether Win XP 32-bit is limited to 2GB or 4GB, and I can't find any workarounds for my current setup.
Any ideas?

Another test I've done is to enable boot logging with Win XP. This appends command lines to the file 'ntbtlog' in the windows directory, which mainly shows drivers being loaded as Win XP is launched. The log is normally date and time-stamped for every boot-logging session.
When all 3 sticks are installed, I cold boot, then press F8 and select 'enable boot logging' from the options menu. This is what appears on the screen as the system, attempts to load Win XP.
Loaded driver \WINDOWS\system32\ntoskrnl.exe
Loaded driver \WINDOWS\system32\hal.dll
Loaded driver \WINDOWS\system32\KDCOM.DLL
Loaded driver \WINDOWS\system32\BOOTVID.dll
Loaded driver ACPI.sys
Loaded driver \WINDOWS\System32\DRIVERS\WMILIB.SYS
Loaded driver pci.sys
Loaded driver isapnp.sys
Loaded driver viaide.sys
Loaded driver \WINDOWS\System32\DRIVERS\PCIIDEX.SYS
Loaded driver MountMgr.sys
Loaded driver ftdisk.sys
Loaded driver PartMgr.sys
Loaded driver VolSnap.sys
Loaded driver atapi.sys
Loaded driver disk.sys
Loaded driver \WINDOWS\System32\DRIVERS\CLASSPNP.SYS
Loaded driver fltmgr.sys
Loaded driver sr.sys
Loaded driver PxHelp20.sys
Loaded driver KSecDD.sys
Loaded driver Ntfs.sys
Loaded driver NDIS.sys
Loaded driver Mup.sys
Loaded driver BTHidMgr.sys
Then the process freezes and a solid white block appears in the top-left of the screen, with the top-right corner of the block blinking.
At this point, I turn off the PC using the main power switch, then remove the 3rd memory stick. After booting up again, with only 2 sticks installed, opening the text file 'ntbtlog' reveals that this boot event wasn't logged.
So, I reboot Win XP with only the 2 sticks installed, and select 'enable boot logging'. This time, the above list of loaded drivers is shown in the text file, plus a whole lot more. The potentially interesting observation is the next in the list after "Loaded driver BTHidMgr.sys" which is "Loaded driver \SystemRoot\System32\DRIVERS\amdk7.sys".
'amdk7.sys' is a driver file which seems to come with one of the Win XP Service Packs, and which "is necessary to enable Windows XP support for AMD PowerNow! technology on computers that use a mobile Athlon 4 or mobile Duron processor." http://support.microsoft.com/kb/306458
Various other posts refer to it in relation to AMD Athlon XP 3000+ Mobile, whereas mine is a 3000+ in a desktop. Also, if 'amdk7.sys' isn't available, then Win XP will load the generic driver 'processr.sys'. In fact, my 'ntbtlog' includes the entry "Did not load driver \SystemRoot\System32\DRIVERS\processr.sys" which would make sense.
However, my curiosity is that with the 3 sticks installed, Win XP fails to continue loading when reaching 'amdk7.sys' in the driver list.
Another test I did was to change the power management settings in the BIOS.
"IPCA Function: This item is to activate the ACPI (Advanced Configuration and Power
Management Interface) function. If your operating system is ACPI-aware, such
as Windows 98SE/2000/ME, select Yes. Available options: Yes, No."
This was normally set to Yes. When I set it to No and rebooted with 3 sticks installed, instead of a half-blinking white block (as described above), the screen went black and then the system rebooted itself...
The plot thickens!...
Maybe there's a clear explanation for this - however, I'm wary of doing something to the 'amdk7.sys' driver file (whether removing or disabling it somehow) in case it prevents Win XP from launching with just my 2 sticks installed. I'd guess there are precautions, but need further info on whether this is relevant, and what the implications might be.

Hi gruberstuber,
It sounds horribly like you're IBM Deskstar may be living up to it's more threatening nickname of DeathStar. These HDDs have a pretty awful history for reliability and from the symptoms you describe, I would be feeling pretty nervous about continuing with it.
Do you have access to another known good HDD at all, preferably from Western Digital or Maxtor? If you do, it would be worth substituting your IBM for one of these and giving that a go. Might work wonders.
It's not as likely, but it's possible that your PSU is rated slightly to small for the Graphics Card you're using. The GF4 4600 is notoriously power hungry and it is possible that this could be drawing your main voltages down to below -5% of the nominal voltage, this can cause you all sorts of weird problems. As a guide, you can't really tell if a PSU is holding up OK under load conditions by checking the voltages when the system is unloaded, all PSU's will give you terrific voltages in that situation.
I would go up to at least a 400W good quality PSU from either Antec or Enermax to be absolutely sure that the GF4 4600 is being catered for.
All the best,
Dimal.

KT4 Ultra (MS-6590) and Ati Radeon 8500

Hello. First of all excuse me for my english, but I'm italian
After upgrading from 1.2 to 1.3 bios I had visualization errors in Windows XP (vertical black lines, font corruptions, ecc), so I decided to downgrade bios to version 1.2. Now MSI released 1.4 bios and I upgraded to this new version with the hope they had solved these problems, but they hadn't. Then I tried to disable AGP Fast Write and now Windows looks fine even if sometimes there are some black screens for few milliseconds during gaming.
There is someone that have my same problems? Any suggestion? I don't want to leave 1.2 bios forever

KT4 Ultra (MS-6590) no display when boots

I recently went out and bought a KT4 Ultra (ms-6590) and when i installed my new ATI radeon 9500 pro i get no display when booting. So i then installed my older Nvidia TNT2 M64 32mb card and i still get no display. my system has not sucessfully booted yet with this board and it is my first time using it. and i thought it might be trying to load from the onboard video but come to find it there is none. What is wrong?
KT4 Ultra (MS-6590)

It might be possible it is a bad AGP slot. Especially if two different cards and no difference.
Is everything else booting? I mean can you tell if the system is proceeding through POST?
It sounds like you just went to a store and bought this board? Can you attempt a return and try another?

ok i am ready to off myself with this thing.....i backed up the needed software then swapped motherboards, as well as CPU....also changed the video cards. First was that everuything started going wrong...windows would crash to a blue screen that went by lightning fast since my pc would reboot itself.....then it would post start loading windows then reboot itself. I adjusted every bios option for close to 8 hrs last night to seee what would work. when i finally got into windows in safe mode it might or might not reboot. No sign of the third hdd (what am I doing wrong here...or can that IDE3 not be used as a standard third hdd) so i swapped back the original vid card since that usually is a prob, but no real diff.....so i formatted completely the #1 drive and relaoded xp home complete clean install......went thru the whole thing ok but when i tried to download the SP1 the computer started the whole rebooting itself over again. WHAAAAAA!!!!! does any one have any ideas, since the only diff in the pc now is the mb and processor, i did the clean install using my orginal video card with the hopes of installing it again later. I did install the MSI IDE driver, the broadband driver and the USB2.0 driver found on the disk, but i didn't install the others since it said not to under windows XP...should I have installed that whole 4 in 1 driver thing with the agp driver for VIA??? i searched the net and have been to 100's of sites before posting here, all with thwe hopes of figuring this thing out for myself, but i am at your collective mercy. please help whille i figure out where i out those darn bullets.......

interestingly, it seems somewhat fixed...sorta...installed new via 4in1 drivers which allowed me to then istall WDM for my video card.....now i am stuck with trying to get the HDD on the IDE3 to be recognized....i tried enabling raid but XP keeps telling me that it can't install the raid driver becuase "data is invalid"......what the hell does that mean...tried every diff version of the ware but no luck....why can't the friggin bios have an IDE 3 enable thing....or i wonder how else i might be able to get this all to work.....hasn't crashed in 4 hrs which is a triumph

I have done fdisk, Partition Magic format, windows install format, and format but I keep get this error. I thought that it was was the hard drive but I try install XP on my ASUS K7V mobo and it work without a prob.
The reason I reinstall is to turn off the APIC and APCI so I can stop the infinite loop error I been getting. I have restore the default setting and still doesn't work.

This had happened to me a few months ago. What had happened on my system was that the Book Sector to the hard drive had been overwritten.
I loaded the recovery console from the XP CD and wrote a new one on there. Then the system loaded perfectly. No problems since.
Hope this may help

KT4 Ultra FSB prob! HELP!

Hey all,
I'm having an issue trying to get my fsb up to 133mhz w/ the kt4 ultra. It sticks at 100. Also it's detecting my processor speed as a 1500 instead of the 2100xp that it is. I hope you guys can help me, it seems like I'm not the only one to have this problem. My other hardware is great, just moved it over from an old computer. I'm still new at this whole msi thing, so any help would be greatly appreciated. Here's my hardware config too. Thanks guys,

Hi,
Did you set in the BIOS - CPU FSB to 133Mhz?
Start read here, most probably is cooler location or thermal grease application, as ur PSU seems OK.

KT4 Ultra (MS-6590) USB controller issues?

Okay, here's another for you guys to ponder....
I bought a 256MB flash drive from Walmart a year or so ago, and it works great with every system I've ever pluggged it into, except my KT4 Ultra. No matter which USB port I plug it into, it's extremely slow to respond and never gets beyond Unknown device, with most times not even getting that far. In many cases it just hangs out there from the socket and looks pretty with no effect whatsoever. I eventually gave up fighting with it, figuring it to be a WallyWorld hardware incompatibility issue.
Tonight I got a 2GB flash drive from OfficeMax and was somewhat dismayed to see it had the exact same reaction to the KT4 MB. I have unistalled all the USB devices and controllers and re-installed with the most up to date drivers, and I've made sure that the USB settings in BIOS are all enabled, all to no effect.
I have several other USB devices (Mouse, keyboard, Canon Printer, Dazzle Video Creator, Wingman Formula Racing Wheel, and various external USB harddrives that all work with this system. I have also had friends bring their flashDrives over and theirs plug in and work fine. ANyone know what the heck is the problem with the ones that I buy?
here they are:
Walmart SDUFDW-256
OfficeMax SanDisk cruzer micro 2.0GB SDCZ6-2048RB

Sounds like pin 10 issue

KT4 Ultra (MS-6590) very slow boot

i got a strange one here:
i replaced my MSI K7T Turbo2 with a KT4 Ultra. Since i got the new board installed (the KT4 Ultra) the machine needs very long until it reads mbr of the disk. what i exactly mean is, post boot goes with normal speed. all settings (FSB speed, DDR speed, CPU speed) are correct. after post boot, when it should start to load windows from the disk, it takes > 1 minute until the boot screen of windows shows up. after windows could boot, i don't have any problems anymore (speed rocks). i did not have this problem with the K7T Turbo2 board and except memory i still use the same components:
MSI KT4 Ultra w 1.4 BIOS
AMD Athlon XP 2000+ (not oc'ed) (~36-43C)
MSI G4Ti4200-TD(MS-8870)
Adaptec 39160 64bit dual (in a 32bit slot ;( )
3*Seagate ST318452LW X15 Ultra160 15K RPM
1 GB PC-2700 DDR (2x512MB)
Creative Soundblaster Audigy Gamer
Compaq NC3123 FastEthernet NIC
Logitech Mousman (dual optical) USB
Microsoft Sidewinder USB
the boot delay was not only when booting from the disks, i had the same experience when booting from cdrom: after post boot about 1 min. nothing and then excpected speed.
any idea?
thanks sidderz

thanks for the hints,
at the stage where boot is delayed so bad, HD access has not even been happened. the OS did not even start to load. so i don't believe the OS has anything to do with it. (except msi found a way to load the OS without read access to the drives )
like i said, right after post boot after floppy seek (my boot order: floppy, cdrom, scsi id 0) the machine just stops (for me it looks like bios is waiting for an answer and then times out) with a black monitor (but signal seems to be still there cause the monitor doesn't go to stand-by). first i thought about an IRQ conflict, but i took care to not use pci slots with shared IRQ's. when the computer starts to read from the disks, boot process is fast as expected. but until the system even starts to boot the os from the disks (read access to mbr on disks), more than one minute just nothing happens, not even disk access. i also checked if the computer is just frozen, but this was not the case, at least the keyboard was not frozen (numlock/capslock and reboot with ctrl+alt+del still worked)
honestly i believe it's a bios issue

Kt4 ultra-sr 6590 problems

Help! Just got done putting together my new computer. Installed everything, turn on power and it starts to post. However, a little error comes up and says cmos/ checksum bad! It says press f1 or f2 to get to bios but i cant get the board to find my keyboard. Ive tried ps2 port and all usb ports but no go. Ive tried three different kinds of keyboards with usb and ps2 connectors, but still nothing! everthing else has power on the board. PLease help! later

Thx for reply! Well i kinda tried that already, but for some strange reason the cmos reset came in the 2-3 position. So i thought that might be the reason but when i put the cmos reset in the 1-2 position the power button wont even work. When i put it back on the 2-3 position it will post, but same problem ;( According to the book i swear it should have come in the 1-2 position. Im sorry if i sound like a tard but im a 36 year old computer noob :D Please help im dying to try my new puter! thx )

Win XP will not install on K9N4 Ultra based system, please help!

Hello, i was hoping some1 could help me with a problem ive been trying to sort out for the past week or so. After buying and building a new system i havent been able to get Windows XP to install, the setup formats and copies the initial files correctly then restarts the computer for the first time, the Windows logo then displays on the screen but after that the screen goes blank and nothing happens, the HD led flashes regularly but nothing else happens. Ive tried installing with both XP home and pro, neither worked, installing Vista works without any problems. I have tried using the Sata drivers from the motherboard CD and from MSI website but that doesnt make any difference, ive also checked the CPU temp which at idle is 25C. Ive tried pretty much everything i can think of without buying extra components to try which i am reluctant to do. On one occasion XP did install but at the time i was trying to install to the second hard drive with a failed install still on the first hard drive, thinking that whatever was causing the problem had been solved i then formatted both drives to do reinstall so that i wouldnt have to screw around with the boot record manually, ive since tried recreating this situation but it hasnt worked when i tried it a second time. Ive tried installing with only one hard drive installed with a freshly made partition and full format and it still did not work.
My specs are:
MSI K9N4 Ultra-F
AMD AM2 X2 3800+
Corsair DDR2 667Mhz 2 DIMMS 1Gb each
MSI Geforce 7300GT 256Mb
Seagate Barracude 7200.9 Sata2 hard disks (2) 250Gb each
450W Win Power PSU
There is also a Creative Sound blaster audigy sound card and a samsung DVD RW, nothing else is connected.
The only thing that i could think might be a problem is the PSU which is a pretty cheap one, also only has 20 pin and 4 pin connecters (both are connected) but i was under the impression that this would be ok.
If anyone has any ideas or knows something i dont about why this isnt working with XP please let me know.
Thanks

Have you checked the memory timings in BIOS Setup? At one time MSI used to just get them wrong and I recall having to set DDR CL to 3 (correct for the DIMMs I had), instead of the 2.5 it chose - no idea on DDR2 though but check that your Corsair specs cross-check with what's used. Is the Sound Blaster Audigy installed? If so try taking it out and go into BIOS Setup and Load Optimized Defaults, then disable all the "fluff" which is not absolutely necessary for a basic install, like on-board audio, ethernet, unused IDE/SATA channels, FireWire(?) etc. You want to get down to a minimum required Windows driver set and if that helps, start adding things back one by one. Also check your mbrd seating for shorts and the CPU heatsink seating... does the CPU temp look right in BIOS Setup.

KT4 Ultra (MS-6590) Please help me!
