KT3 Ultra2 & FSB

Alright, the problem is that from a cold boot, the systems hangs with loading an OS at 166fsb. The cpu usually runs at 166x10.5 but dropping it down to 166x10 or 9.5 does no good so I know it is not the processor. The ram is 2-512MB sticks of PC3500 hyperx (looking to use this in a newer system and putting pc2700 samsung back in current). There is no setting in the bios that makes it stable (have tried them all in groups of ~5 changes per boot). The psu is an Antec 300w which is only required to power mb, video, nic, 1 hd, 1 cd, and 2-120mm fans so it shouldn't be at fault. The system will simply not boot up using a 166/167/etc fsb (haven't bothered with 152(?)-165 which is the range of the 1/5 divider) until the system has been running for awhile, sooner if I get the system going with a game or something. Then I can reboot and throw the fsb up, stable up to 183. The question, why does it not boot at 166fsb from a power-off state? Latest BIOS. Any ideas?
Currently running at 133x12.5

The following was typed up and supposed to be posted last night but comcast decided to crap out and not work until now
Antec PP-303X 300W
I've been reading up and it looks like it depends on where the motherboard gets most of its current. If its from the 5v rail, there shouldn't be much of a problem, but if it gets most of it from 3.3, then there's a problem. I didn't realize some motherboards use one rail over another depending on design.
It looks as if this psu was designed in mind with a motherboard pulling off the +5, but I'm having problems finding technical documents for the KT3 Ultra2. The CPU itself should be draining about 20 amps by itself at load according to the calculations that were made, which leads me to believe this motherboard is pulling from 5v as the 3.3 on this power supply is very unefficient for this use. The weird thing is, their truepower series doesn't put out much more, if any, power on the 5v rail than the current psu and if this motherboard is designed to take what it can from the 5v, it doesn't appear the decision to buy a new antec power supply is a good one, unless its the 530watt varient which puts out 40amps on +5. I'm going to look into tring a different power supply tomorrow and see if it fixes the 166fsb problems. In the mean time, anyone know where I can find technical documents for this motherboard? Its the most difficult piece of hardware to find detailed information on.
Added now:
From what I've learned, a lot of the time the ram feeds off the 5v line, again depending on the motherboard. Nowhere in the spec sheets of hyperx does it claims to use 40 watts per stick of ram. I'll try readng over my nonsense post later today when I'm more awake as its 6:55am right now and it was 1am last night. Going to stop by the bank today and head out to probably pickup antec's 530w psu.

KT3 Ultra2 FSB speed after BIOS upgrade

I have just upgraded the BIOS on my KT3 Ultra2 mainboard. On the CPU Support page, it says my mainboard support CPUs with FSB @ 333 MHz with the newest BIOS, but in the manual it says that the FSB is @ 200/266 MHz. Did the BIOS upgrade increase the FSB so that the FSB now is @ 200/266/333 MHz?

it increased the options,you still have to set it after flashing though

KT3 Ultra2 AMD 2800+ won't boot at 166 fsb

Hello guys / girls,
I've searched the database multiple times for this, but couldn't find anyone with the same problem:
My computer won't boot into windows or linux at fsb 166, it crashes during starting of the OS. When I reduce the fsb to 160, everything runs fine. First I thought it was the processor which would get too hot, but it's not getting too hot, only 27 C idle!!! The proc is designed to run at 333 / 2 = 166 mhz fsb so I don't see what's going wrong...
My specs:
KT3 Ultra2 mainboard
AMD 2800+ proc
noname psu: +3.3 28 A, +5 30 A, +12 15 A
Thermaltake volcano 7+ fan at low speed, gives proc temp of 27 deg. C idle
Kingston DDR-SDRAM PC3200 - 512 MBytes
CPU-Z info: http://bootje.servebeer.com/transfer/cpuz.htm

But why is it working at an fsb of 160 mhz?? I am using that configuration now, and no problem. The problems start when I increase the fsb to 162 or higher...
Also, according to the guy who sold me the memory, the memory should also work at 333 mhz.
Before I had an XP2800+ proc, I had a XP1700+ proc, which ran at a default fsb of 133 (tweaked to 140 (of course)), with the same configuration as I have now, and no problems at all... So the memory then ran at 266 mhz, thats even lower than 333... But i'll give it a go with different memory, but I can only do that after the weekend (roommate with other memory is gone for the weekend...)
Anyone other suggestions what the problem could be??

KT3 Ultra2-R ... Can't change FSB beyond 100

Dear all,
Just got my KT3 Ultra2-R with an Athlon XP2100, upgraded to 5.7 AMI BIOS, worked great, then made some changes to CMOS (forgot which ones), then couldn't boot.
When I finally booted and went to CMOS setup, it would not let me change the FSB to anything other than 100...that is, no options on the FSB when I hit enter (shrug).
Now, my system recognizes the CPU as an AMD XP 1500...blah. Tried everything...resetting CMOS with jumper, took out computer battery, replace 350 SmartBlue PSU with 400 Watt PSU, replaced Heatsink/cooler with better one, wiped contacts, nothing...it's not the temps, because my case idles at 29C chassis and 36C CPU temps. Even reflashed back to BIOS version 5.6, and still no go.
When I do "performance" settings in CMOS, it will give me 133 FSB, but my system will now be unstable. Weird thing was, before this "event", performance setting put it at 166 FSB :(
Anyway, my comp isn't dead....it just won't let me change the FSB. I called up ABS Computers where I bought this, and they said they are not responsible for damage caused from flashing BIOS...blah, whatever.
I just put out an order for an Asus A7N8X Deluxe motherboard and joined the NForce2 bandwagon, but if someone could give me some insight into what I could do about my motherboard, besides hang it on my wall, I'd certainly appreciate it.
Here are specs of my system:
MSI Kt3 Ultra2-R
Athlon XP2100
Geforce2 video card
soundblaster 5.1 Live
WD 120 Gig and WD 60 Gig
Liteon CRWD
Sony DRU-500AX
Q-Tech Quiet PSU 400 Watts
Nexus Heatsink/Fan
Windows XP Home

Thanks for the reply, but while checking out the other problem with the KT4V / Athlon 2400 Clock Speed Problem (above) who couldn't set his FSB beyond 100, but when he set it the multiplier to 12.5/13, he gets a 20X multiplier when he goes into Fuzzy Logic.
Well, guess what, I did the same thing (set my CPU multiplier in BIOS to 12.5/13, and lo and behold, I go into fuzzy logic, and my AMD XP 2100 is recognized as an AMD XP2600 running at 2000 megahertz...now someone explain that to me! I even check with SiSandra, and yup, it's seeing a 2000 megahertz processor. I even ran the benchmark tests on SiSandra, and it's on par with that processor.
However, my FSB is only 100, and thus, my memory benchmarks are about 25% below the norm for my DDR333 RAM chips (i guess because they are synchronized with the FSB, and probably running at 200 then).
Anyhoo, i'm tired of trouble shooting and figuring out what the hell is going on. The comp is extremely stable at 2000 megahertz at 100 FSB...don't know what else to do...so installing new motherboard tomorrow and report back later.

MSI KT3 Ultra2-CLS and 166Mhz FSB

I own a KT3 Ultra2-CL and a Athlon 1400C.
At the moment it runs 11,5x133 = 1533Mhz. Stable.
It also runs 9x166 = 1500. Stable, but my PCI runs 41Mhz.
So please implement the correct divider in very near future bios update.
It should not be true that customers, who invest less money in a new mainboard than others, can´t use all of the functions the chipset provides. I WANT TO RUN 166Mhz FSB WITH 33Mhz PCI
All of your "expensive" boards provide this divider.
IS THIS MAREKTING 2003???
Best regards

One AGP slot
- AGP (Accelerated Graphics Port) specification compliant
- Supports AGP 2.0 1x/2x/4x
so whats the problem,your fine there

KT3 Ultra2-C FSB support?

About 13 months ago I purchased a prebuilt PC system and made the mistake of assuming (based on the name) that the KT3 Ultra2-C (MS-6593) was similar to the rest of the KT3 Ultra2 line, which I had heard good things about, and I expected similar future processor support. In fact if you do a Google search you will dig up some old news releases that even state that MS-6593 supports Barton CPUs. Flash forward in time, and I discover that despite the extremely similar name, the Ultra2-C apparently does not support the newer 333 FSB CPUs. A search on this site comes up with some posts that say this is because the Ultra2-C doesn't even have the 1/5 divider, so the PCI speeds at 166 will be far out of spec.
Can anyone confirm if they have gotten Bartons to work with this motherboard? Or otherwise confirm if this board is in fact lacking a 1/5 divider at 166 FSB? Can this be fixed with a BIOS update?
The BIOS allows one to set a CPU FSB up to 200 mhz, and the board came with overclocking utilities, etc. Speaking as an engineer myself, it is completely illogical to make a product that supports high FSB but does not have a 1/5 DIVIDER at 166! I also can't believe a company would release a product with such a similar name yet have such critical differences in features.
Signed,
Confused and Disappointed

Yepp, it does not have the 1/5 divider, similar to the KT3 Ultra-ARU. But the Ultra-ARU is often reportet to run at FSB166, but it is not official

AMD says MSI KT3 Ultra2 will support 166 MHz FSB

Here's the link:
http://www.amd.com/us-en/Processors/ProductInformation/0,,30_182_869_4348^4378|123_1_XP,00.html
What's really interesting to me here is that apparently bios version 5.7 , with an AMD-reported release date of 10/23/02, is what will actually allow the KT3 Ultra2 to support the 166MHz FSB.
It looks very much to me as if the KT3 Ultra and the KT3 Ultra2's not only share the same model number but also the same bioses as well.
What would prevent bios 5.7, when MSI releases it to the public, from supporting a 166MHz fsb in the KT3-U's as well as the the KT3-U2's?

Thanks for the link, Wonk... I had actually read through that thread and kind of came away with the impression that although MSI said the KT3 U would not support a 166MHz FSB, nobody was really sure enough about that to place bets on it...
Anyway, I only ran across this info on the AMD site last night--apparently it's new info, and runs in tandem with a rumor over on the Inquirer http://www.theinquirer.net/?article=6032
which states that AMD is going to announce 166MHz FSB 2600's tomorrow--and if not tomorrow then shortly before Comdex. I have to admit this info on the AMD site lends some credence to the idea.
What's interesting to me as well is that on this same list the KT4 Ultra is not listed as supporting the 166MHz fsb 2600 +, at least with its present bios.
Hmmmm.....

USB 2.0 Issues with KT3 Ultra2 6380E

Windows XP SP1
Bios: American Megatrends Inc. 07.00T
Hi I was wondering if someone could help me?
My machine has six USB ports. (1&2) Two ports are
installed on the motherboard, and my users guide says
they are legacy ports. (3&4) two ports are installed
on the d-bracket 2 connector: JLED, connected to
JUSB2, these are what I believe to be my only 2 USB2.0
ports. (4&6)Finally 2 ports are connected via JUSB3 to
the front panel of my Antec case. I think the front
panel of my case has 1.1 connectors so it is
essentially a 1.1 port.
I am having some difficulty getting my USB ports to
function properly with a USB 2.0 Buslink hard drive
UII-40 72E. I suspect there is some IRQ conflict.
Trying to alleviate this I disabled all the device
drivers I suspected might cause this in the device
manager in safe mode. I then removed from the device
manager all the USB (2.0 and 1.1) root hubs, and after
that their host controllers. I then booted to VGA
mode (thinking this should disable the video card
drivers??) and exported this IRQ info from my sys info
after the USB host controllers are reinstalled:
Resource   Device   Status
IRQ 9   Microsoft ACPI-Compliant System   OK
IRQ 11   RADEON 8500 SERIES    OK
IRQ 21   VIA Rev 5 or later USB Universal Host
Controller   OK
IRQ 21   VIA Rev 5 or later USB Universal Host
Controller   OK
IRQ 21   VIA Rev 5 or later USB Universal Host
Controller   OK
IRQ 21   Standard Enhanced PCI to USB Host Controller   OK
IRQ 0   System timer   OK
IRQ 8   System CMOS/real time clock   OK
IRQ 13   Numeric data processor   OK
IRQ 12   PS/2 Compatible Mouse   OK
IRQ 1   Standard 101/102-Key or Microsoft Natural PS/2
Keyboard   OK
IRQ 14   Primary IDE Channel   OK
IRQ 15   Secondary IDE Channel   OK
IRQ 6   Standard floppy disk controller   OK
Next I attempt to (already plugged into D-Bracket
port) power on my buslink USB 2.0 hard drive. As soon
as I do the machine immediately goes to a blue screen.
No messages given but numbers are shown. I have screen
shots taking with my digital camera. I then returned
to safe mode, remove the USB drivers as I did before,
and boot to VGA mode. Once the USB drivers have been
restored I attempt to power on the bus link hard drive
this time plugged into the onboard legacy ports. I
can I get another blue screen this time including a
message "IRQL not less or equal", again I have taken
screen shots with my digital camera.I then returned to
safe mode, remove the USB drivers as I did before, and
boot to VGA mode. Once the USB drivers have been
restored I attempt to power on the bus link hard drive
this time plugged into the front panel USB ports
(4&6). When I power it on Windows XP warns me that I
have a high-speed USB device plugged into a non
high-speed USB hub. But I receive no error messages.
However I do not exceed the drive through "my
computer". I go through the add hardware wizard to try
and at the drive manually and it says the device is
working properly. Still I do not see the drive.
Finally I tried installing a Buslink USB 2.0 PCI card
after the above steps. I then returned to safe mode,
remove the USB drivers as I did before, and boot to
VGA mode. Once the USB drivers have been restored I
attempt to power on the bus link hard drive this time
plugged into the PCI card. The drive seems to be
recognized automatically by Windows XP however my
system slows to a crawl trying to access any hard
drive. When I try and access the USB 2.0 hard drive I
get a message something to the effect of "(the drive
letter) not being recognizable".
Any ideas on what could be causing this? The same
Buslink hard drive works great at work on my Windows
2000 machine plugged into the same PCI card using the same USB cable and power supply. Would any other information be useful?
Thanks!

I first tried installing the VIA4in1 and VIA USB2.0 patch. Then I tried the D-bracket after refreshing the usb drivers (I did not disable all other devices like in my original post, should I have?). Same result, blue screen crash at power on.
Next I disable USB ports in BIOS and install USB PCI card. Then power on the USB HD plugged into card. Same result. Computer slow accessing local drives. When I try to access the USB drive I get a "E:/ is not accessible; the file or data is corrupted or unreadable."
Next I remove the USB card. I enter BIOS and set to "2" ports. Presumably this turns on the USB1.1 ports on the mobo. I return to windows xp. It now seems to install the drivers, but just as it finishes I get a "a problem has been encountered instaaling this device (it has done this before but after finishing I get the blue screen most times). Next I goto the device manager, and in my USB devices I have a USB mass storage device w/ a yellow flag. I goto properties and see a:
"the device cannot start (code 10)" device status. I click "troubleshoot" and voila... blue screen.
Finally I reboot, and set 4 ports in BIOS, making my JUSB3 FRONT PANEL usb1.1? ports active. Interestingly these respond like the PCI card. Computer slow accessing local drives. When I try to access the USB drive I get a "E:/ is not accessible; the file or data is corrupted or unreadable." As soon as I power off the USB HD things are normal...
I will take this USB HD to work tomorrow just to ensure its integrity. Any other ideas? What kinds of BIOS settings might F up USB?

Lack of Ghz KT3 Ultra2 Barton 3000+

Dont want to sound like a broken record but I aswell am having problems with my newly purchased Barton 3000+ (400 fsb) with my MSI KT3 Ultra2. The problem is that whenever I try to set the FSB to the correct level, the computer fails to boot and I have to jump the cmos. I updated my bios to ver 5.7, and the highest i can get is to a 2400+
Two possible reasons I think are I have a Thermaltake Volcano 8 (which i believe isnt up to par) and my powersupply is a bit below the specs in the troubleshooting faq: L&C brand PSU +3.3V/24A +5V/35A +12V/12A. However I'm reluctant to go buy replacement parts because I've read of the people who did and it didnt help (limited budget.)
I've tried flashing with 3 different versions of 5.7 drivers, and even gave the 5.6 a go (highest i could get was 2200+) The highest I could get the FSB is to 199, but as soon as i try for 200 it zonks out on me. I've got 768 megs of no name ram that has served me well, and so thats not the problem... (hope not) I've also read a buncho topics and tried various things from them.
If I missed anything lemme know....
Oh while I'm here, my computer likes to restart itself whenever I tell it to shutdown. Sometimes it does stay off, usually when not running for very long. On occasion (not very often) It will come on on its own accord, which kinda concerns me

I don't know for sure, but aren't there two different types of Barton's being sold. One with a FSB 333 and one with 400 ?
So I think you will have to get the other type in order to get it working, since the mobo does only support FSB up to 333 MHz.
Maybe you can just replace the CPU where you bought it ?

BIOS Settings Problem on KT3 Ultra2 MS-6380E with Barton 3000+(FSB333)

Well, I finally got my Barton 3000+ with 333 MHz FSB and installed it yesterday in my MSI KT3 Ultra2 Mainboard....
System Before changing anything:
PSU: DTK 400 W
+3.3 V / 22 A
+5 V / 35 A
+12 V / 15 A
-5 V / 0.5 A
-12 V / 0.8 A
+5 V VSB / 3 A
So that should make up 400 W as far as I know, my total System drain should be around 300-350 W so even if it would not suffice 400 W it should run the system ?
Mainboard: KT3 Ultra 2 (BIOS v5.7)
CPU: AMD XP 2100 FSB 133 MHz
RAM: 1.536 MB, 3x512 MB Infineon PC3200 (400MHz) CL 3-3-3-8 @400MHz, Cl2.5-3-3-7@333Mhz, 2-2-2-6@266MHz

Monitor: Samsung Syncmaster 172T with Driver Version 1.0
Printer: HP Deskjet 970Cxi with Original HP Driver Version 4.3
OS: Windows 2000 Professional with Service Pack 4
BIOS Settings: SDRAM 1T Command: "Disabled" It won't work stable with 3 RAM's in it with that setting, but that I did know before.
CPU Fast Command: "Ultra"
System was running stable for nearly 2 years with this Configuration:
So now it goes:
First I changed the CPU form my old AMD XP 2100+ to the new Barton 3000 + with its new Arctic Cool Copper Silent 2TC.
Then I went into BIOS and raised the FSB to 166 MHz, which should be the correct one, or do I have to put 167 MHz in there (since 166.666666 MHz is rounded to 167)?
Then I exited and watched the restart...but it didn't start-up it only got me 3 long beeps at the HOST.
After some whining and beating I plugged out anything and cleared CMOS and started the whole thing again:
System after Clearing CMOS:
Mainboard: KT3 Ultra 2 (BIOS v5.7)
CPU: AMD XP 3000+ FSB 100 MHz
RAM: 1x512 MB Infineon PC3200 CL 2-3-3-7 (BIOS setting CAS Latency by "SPD")
Storage: Western Digital WD800BB (80 GB) (Firmware 17.07W17)
Monitor: Samsung Syncmaster 172T with Driver Version 1.0
OS: Windows 2000 Professional with Service Pack 4
With all Default settings, the Computer boots up, and is correctly Recognized as a Barton 1300 MHz.
When increasing FSB to 133 MHz it is correctly displayed as a Barton 2200+
NOW...
...after adding one BIOS setting after another I narrowed the problem down to the "CPU Fast Command (decode)" Function...if set to Ultra it does not boot-up when running 166 MHz FSB, it does not even let me into BIOS. I have to clear CMOS and restart from scratch again...
Is this normal and expectable with a Barton 3000+ running at the native 166 MHz FSB or not ?
Since my system before was running on "Ultra" with my old AMD XP 2100+.
There is only one more thing I noticed, the CPU V-Core is shown to be only 1.616 V (setting on "Auto" but it should be 1.65 V ? Should I increase the V-Core to 1.675 V in order to get closer to 1.65 V or shouldn't I worry about ?
Thanks for any Input you can give me on the problem.

Iscaran, you are indeed correct in the statement which you made

This setting can be set to fast/ultra on the KT3 Ultra2 when using PC2100 ram running at 266. However, when using PC2700 ram running at 333, this setting MUST be set to normal for the satisfactory operation of the board. I know that you have PC3200 ram actually installed but it is only running at 333.

How are you measuring this ie Bios or o/s utility? Not unknown that these are incorrect. However, if you feel unhappy about this, try setting the V-core manually to 1.65v and check what this gives.

So 3.3 V x 22 A gives 72.6 W, that could be really a little cutting the edge. Could that cause the board to not respond when setting the "CPU Fast Command" to "Ultra" ?
Getting a more powerful psu will not likely cure this well documented problem.
However, this board mostly draws power from the 3.3 & 5v rails. The 12v is mostly used to power HDD, optical and fans. When you consider that 128Mb of ram draws about 8-10w from the 5v rail and you have a total of 1.5Gb that adds up to 96-120W of juice just for the memory alone. This board will beep at you at o/s level when it's running underpowered but my opinion is the same as osnavi's your 3.3v & 5v rails are too low. Also what is combined 3.3v & 5v wattage. What kind of reading do you get on monitoring utilities.
By the way I have as you can see from my dets below the same board and cpu as you and when I changed from a XP2000 Palomino with PC2100 ram to XP3000 Barton and PC3200, I changed the 'Fast Command' setting from 'Fast' to 'Normal'
Hope this helps, enjoy the board

KT3 Ultra2 won't run XP 2500 at more than 151 Mhz

Not an unusual topic I know but I haven't found any solutions in this forum as yet!
With my XP 2000 cpu installed my system is stable when the FSB is overclocked to 150 Mhz. When I install the XP 2500 cpu and set the FSB in the BIOS (latest vertsion) to 166 Mhz it won't access the hard drives at all. My initial thought was the psu so I reduced the system to 1 hdd, 1 DVD rewriter, 256Mb memory and tried again. No change! Then I started reducing the FSB until at 151 Mhz it would boot but as an XP 1900 cpu. The VIA chipset drivers are up to date.
I' don't know what to try next. Any ideas?

I can only say, I'm running my KT3 Ultra2 with XP 2800+ without any problem at 333 Mhz. Remember you have to upgrade Bios with ver 5.7 so Mobo can work with a 166 FSB. Also, better try starting with only one memory module. You can take a look at my P.S. specs. on my sig. It's not too good, but enough for this rig. So, don't dispose yet your 2500+, try and tell us how did it go.

KT3 ultra2 BR problem

I have already read Bas' post about the common problems but still, my own problem can't be solved. I hope you guys could help me. Here's the problem:
Specs: KT3 Ultra2 BR/2 x Kingmax 256 MB DDR333 RAM/AthlonXP 2000+
I know that the default fsb is 100. The system reaches POST at 100 fsb. Now, if I use that fsb, my athlon xp is almost worthless. Everytime I try to set the fsb at 133 and saves the CMOS setup, the system couldn't even initialize the VGA card and won't even reach POST. The LEDs tell me that the problems are with the memory modules. I hope you people can help me because I can't use my system until this is solved. Thank you and more power to you.

Could you prove it was 2100? If so, I would have taken it back and shoved it up........ Sorry, got carried away. I would have dobbed the retailer in to the authorities for misrepresentation or fraud.

Can't enter bios on KT3 Ultra2

last night I did a succesful bios upgrade to V5.7 on my KT3 Ultra 2 board.
System rebooted into bios default with no problems and I reset all the parameters as per the previous version.
Unfortunately, I set the FSB to 166 instead of 133 ( Gawd knows what I was thinking of at the time!).
On reboot after saving and exiting the bios setup, I was met with a blank video screen - no beeps came from PC on reboot.
The LED display is showing 1&2 Red, 3&4 Green.
Subsequent reboots show the LED display goes straight to this configuration on power up.
I tried resetting the bios back to the default, but I still have the same symptoms.
DVD , CD-RW and HDD light up during boot up, but nothing seen on the Floppy. Hitting Del or F11 has no effect.
I don't have another PC that will allow me to check CPU, Memory or Video card.
I've tried changing the Memory round and reducing to just one stick. Even ran without memory and still got same symptoms without any beeps during bootup.
At the moment the PC has been powered down and the clear-bios jumper left in 2&3 overnightin an effort to clear the bios.
Where do I go from here?
Now if I've knackered the mobo/bios, how do I stand installing a new mobo/cpu under the existing Windows XP installation on the Master Hard drive ? My last back-up is out of date and having just come back off hols the HDD is full of images I desperately need to keep!
System:
MSI KT3 Ultra2 series mobo; Athlon XP1800+; Matrox G450 Video Card; 512Megs PC2100 DDRMemory; Amibios V5.7; 350W PSU; ample cooling by way of extra fans; Windows XP Home SP1.
All help gratefully received,

I had exactly the same.
my 1900+ has always run at 166*10 with bios rev5.6
I flash to rev 5.7
I was trying 10.5*166 (the cpu has ever done this in the past) when the computer refuses to start.
the D-braket shows : LED 1&2 Red, 3&4 Green.
rest, unplung the bat, the card was dead
I've RMA the card the last week.
All my component works ok on my k7s5a
Is the reset not working with this bios or the bios has kill the card, I don't know !
PS : a friend of mine has a KT266A, the capacitors near the cpu break (the top was bounded). This trouble exist in MSI KT400 card too.

KT3 Ultra2-R won't run 133FSB with XP2000+

Hi there!
I have just bought my self a MSI KT3 Ultra2-R mobo, a TwinMOS 512mb PC333 cas2 ram and a XP2000+ CPU with a GlacialTech HSF (certified for XP2600+)
When everything is in deafult in the bios, my fsb runs at 100mhz. When pumping it up to 133mhz my screen won't initialize and there are no beeps on startup. I have a 350W Enermax PSU that I know works!
Any suggestions to what I can do? Thanks...

Getting rid of the shim did the trick. Now I "only" have a stop at the initialisation of the HD controller. I've read some threads on that problem here, so I think I will be OK very soon .
Thanks all!

KT3 Ultra2 R and VGA problem

I wonder if I could please get some ideas as regard this rather odd problem which I am encountering. This problem occurs when while the pc is 'shut down' if I disconnect the power supply ie switch off power by way of the switch on the psu. When I switch power back on again and boot, the pc begins its booting sequence it begins to launch windows and then it stops and a little red square (with a bit of green) appears in the top left hand corner of the screen. Now this problem does not occur if I shut down the pc normally (but don't cut off power supply). I have several partitions on my HDD and they are all affect at the same time. The end result is that I boot into safe mode I look at the refresh rate which is set to 'unknown' change it to 'adapter default' then reboot but upon reboot I get windows displaying screen at 640x480 with standard vga colours. I check in device manager under 'display adapters' what driver it's showing and it's the driver which I last loaded ie the correct one. I cannot change screen resolution , bit colour and the refresh rate only allows for 2 options, either 'optimal' or 'adapter default'. In order to get back to where I was, I have to remove and re-install my VGA driver and then everyting is back to normal (until I switch off power again at psu then back to square one). I have spoken to the manufacturers of the graphics card and they say that if the card works ok when I shut down pc normally and restart then cannot be the card. I described my problem in greater detail to MSI support and they said either VGA or O/S.
In essence I wanted to isolate the problem to, is it 'hardware or 'software'.
I would be grateful if anyone can shed some light.
KT3 Ultra2 R (5.5 not the right one but the cpu clock speed is correct at post)
XP 2600+ 333 T'Bred
Crucial 512 Mb PC 2700
Leadted Ti 4400 128 MB Vivo (det 44.03)
Creative Audigy
Enermax 432W
Windows 98SE (via 4-1 v 4.34)
Seagate 60Gb 7200rpm I am running the HDDs as independant drives on the
Seagate 40Gb 7200rpm Raid controller ie one on IDE3 & one on IDE4

Odd as it might seem I have to follow the proceedure listed below if I want to switch off power altogether to work on my pc.
1. Cold boot system with 166FSB and let O/S install
2. Reboot enter Bios and reduce FSB to 133 make sure to set memory speed as HCLK and let O/S load
3. Shut down and switch off power supply
4. Reconnect power and boot system. Enter bios set FSB to 166 (the mem speed will be HCLK)
5. System continues to boot and loads O/S
From that point on, cold boots (without cutting power supply) are not problematic as once the 166FSB is 'registered' everything works ok (at every cold boot). So anytime I wanna work on my pc I guess I have to do the above 5 steps. They seem to work but need to try it out a few more times before I am confident that this process will always work.
I am sure you agree that this is one strange mother of a problem.
I suppose the only 2 things left are a total O/S reload or trying another 333 cpu because I have tried everything else. I guess I will have to live with it.
I have also cut some additional front vents so that front fan draws more air in and it appears to have dropped my idle Temp to 40.5C on CPU (running at clock 2083Mhz).
As as said earlier in my post my system ran perfectly with XP2000+ and 512Mb PC2100. I merely upgraded the CPU to XP2600 and mem to PC2700 and it has thrown up this very odd problem. And to boot (if you will pardon the expression) when I first installed new CPU and memory it booted first time at 166FSB. osnavi, in case you upgrade your CPU to a XP2600 and you get this weird problem at least you can come back to to this thread and find this workaround.
I wonder if anyone can fathom out why this is happening.......If not as I said I can live with it.
wonkanoby, I will try the link to the memtest. That is the only thing I have not tested so will give that a try.
