KT4 Ultra Microphone problem

I have a KT4 Ultra and there appears to be an error with the microphone circuit. The PC2001 standard specifies that the Mic Audio is on the tip , 5v bias on the ring and ground on the sleeve.
The KT4 however puts the 5v bias with the audio on the tip. It will not therefore power a standard electret mic.
By moving the centre/subwoofer jumpers J4&5 I can move the audio and 5v to the ring but they are still combined, not separate as they should be.
Also the the signals are wrong on the front panel audio connector JAUD1. Pin 1 has mic input and power combined (instead of just audio) and pin 3 (which should be mic power) sits at 0v.
Before I start cutting tracks and adding jumpers to the board to correct the problem has anyone already worked out the best way of fixing this error ?

Hi,
A normal electret mic has 3 wires.
The only thing you need to do is add a capicitor in the audio wire of the micro of about 10 microF.....
Like this if I'm not mistaken:
Audio+cap to the tip
Powerline to the tip as well
And ground to the shield
This way it should be powered and work.
Then again, I'm not sure, but there is no harm in trying.

KT4 Ultra RAM problems and others

Hi,
just bought KT4 Ultra, with 512MB DDR-RAM 266/2100 CL 2,5 and Athlon XP 2100+, BIOS V1.2.
During boot-up the computer tells me, that I've got 1024 MB RAM although I only have 512MB. Linux says the same and RAM Test Software does too !! I can't install RedHat nor Windows XP, they always crash, prbably due to RAM problem.
I've already tried out all 3 memory slots.
Any suggestion what to do ?
Why does the computer not recognize any device on the 3rd IDE port ( neither IBM Deskstar w/ 40GB, LS 120 Drive, CD-ROM Drive). My BIOS doesn't show ANY options for the 3rd IDE port!
TIA

Is that in the BIOS under: Serial Ata - enabled ? ( I did that !)
Try http://www.memtest86.com
Already did, it always crashes.
Have you tried another RAM?
'Have no other RAM available right now.
And I can't start my computer anymore, since the cpu fan wont work. I plugged the cpu fan into the manboard-fan plug but then the mainboard won't be cooled. That can't work all too long, can it ?

KT4 Ultra IRQ problem

Hello Everybody !!
I have small problem... Two months ago i bought my fantastic KT4 Ultra... :D I'm very happy of that.
Everything works fine, but my agp PNY Geforce4 Ti 4200 has the sam irq 16 like my integrated C-media 8738MX sound card.
The question is:
Is it bad or not ??? If it is bad, how can I change the IRQ for my Geforce card???? Becauce it is impossible to change IRQ in Windows XP. I know that there is possibility to change IRQ in BIOS, but I dont know what PCI slot is shared with AGP.
I will be very grateful for any help.
My configuration:
Windows XP SP1
MSI KT4 Ultra-B
C-Media 8738MX integrated sound card
PNY Verto Geforce4 Ti 4200 64MB
2 x 256 MB DDR333
Lite On 48/12/48
Maxtor 40 GB Ata 100

I had problems with TV cards, had the TV@nywhere and a Leadtek TV2000 XP Delux. I eventually got them both working. Win2k and WinXP disable the control ability of PCI interface which stops you from installing new cards and drivers. I fixed it by
1. First remove any unknow devices in "Device Manager".
2. Run regedit (WinXP) or reget32(Win2K).
3. Check to make sure that "full control" for the profile that you are using i.e. Admin is allowed in KEY_LOCAL_MACHINEsystemControlset001enu mPCI.
3 keys need to be changed to "full control".
Controlset001enumPCI,
Controlset002enumPCI,
CurrentControlsetenumPCI.

Try the new BIOS 1.30 that corrects the CRC ERROR, it will slow down your transfer rate and you should be fine. This is a bad fix from MSI, cuz you lose HDD performance aswell!!

Linux and MSI KT4 Ultra : DVD problems

Hi, I own an MSI KT4 Ultra Pure mobo. The vt8235 Southbridge is supported in the lastest version of the Linux Kernel, 2.4.20 . After upgrading the kernel all seems to work fine, but when the system try to initialize my hdc (Secondary master of IDE, a DVD reader DV-5800A from NEC) it locks up with the message :
hdc: device {Busy}
hdc: drive not ready for command
ide1: reset success!!
and start looping with this message.
What can I do to get work my DVD Reader? With my precedent MoBo it works perfectly
Thanks
Bye

Hmmm that error used to happen with an older kernel and an ALI chipset. If you leave it long enough does it give up trying and continue to boot? The ALI did this eventualy.

Kt4 ultra memory problem

Hey guys, hopefully someone here can recommend some help! I have the kt4 Ultra motherboard and i've had it for about 8 months. I have an amd 2600+ and up until now i've had 2 256mb 266mhz micron ddr ram chips in it. I added a 512mb 266mhz crucial memory chip today. No matter what I do it will never recognize more than 512mb ram. I can just run the 2 256mbs and it recognizes 512, i can just run the new 512 and it recognizes fine, if i put all 3 in (or the 512 and one 256) it reads 512. Everything runs ok, no lockups no reboots anything like that, but i'm out 512mb of ram.
I flashed the bios to the newest version but still no help.
I have the bios set to "spd" and i tried playing around with those numbers but it didn't help.
anyone have any ideas?
thanks in advance!

Yes I am starting to realize that I never should have tried mixing brands. I attempted what you said and its recognizing the 512 only. Any suggestions (besides eating the 15% restocking fee and sending the new one back)?

KT4-Ultra IDE Problem

i've been running a kt4-ulta with barton 2500+ which most of the time runs fine but every now and again the comp doesn't boot "primary master boot fail" so when i go into the bios the hard drive has the name muddled up (instead of "maxtor" it has something like "atxmor") the only way i can seem to fix this is by clearing the cmos but im now getting a bit sick of re-doing all my settings. i was wondering if this is a common fault or my board is f***ed.
any help would be great

Problem with my MSI KT4 Ultra

Hi all!
I have a BIG problem, I have tried to look at this board, but there is many different answers out there ;(
I have KT4 Ultra with Athlon XP 2600+
I have set FSB to 166, and when I startup BIOS says Athlon XP 2600+.
But in windows system, it only says:
AMD Athlon XP2600+
2.09Ghz !!!!
768Mb RAM
Why is windows only says 2.09Ghz??
AND, I think my system is very slow. I used to have AMD 1200Mhz. And this sytem is almost like my last computer.
My System:
MSI KT4 Ultra ( MS-6590 ) with BIOS
CPU AMD Athlon XP 2600+
768MB DDR 400 RAM
GeForce 4 TI4200AGP 8x

Problem with KT4 Ultra and XP 2700

First excuse my bad english (i'm from Germany)!!
I have a heavy problem with my KT4 Ultra.
First my system:
AMD Athlon XP 2700
Mainboard: MSI KT4 Ultra (MS-6590) Bios vers. 1.1
MSI Geforce 4 Ti 4200 64 Mb
512 Mb DDR Ram Apacer Technology 512 MB 16x(32mx8)DDR-SDRAM PC2700U-2533-700(CL2.5 upto 167MHz)(CL2 upto 133MHz
Sound : Onboard
GlobalWIN CAK38 II Kupfer
Powersupply: Levicom 420W
Win XP SP1
Now the problen:
When i turn the FSB in the Bios up to 166MHz
the system crashes on Windows startupscreen!!
I've turned the FSP clock down to 164 MHz and Windows starts.But when i runned 3DMark2001 it crashes back to desktop !!
Then i turned the FSB clock down to 159 MHz and the system runns stabile!!
Now what i've already tried:
Turned down Ram timings and frequency (same prob.)
No heatproblem (CPU at 118.f)
Had the same system exapt an XP1800 instead an XP2700 and no problems!!
Called the MSI hotline (Germany) and they told me to type the FSB manually in the Bios (insted of numblock +and -). ?(
Still the same problem !! ;(
Has anyone the same problem as i ???
THX !!

Hi,
I would try other ram....
Or start from BIOS default settings and only change CPU-FSB....
See what happens...

Kt4 ultra bios 1.3 ati problem

I updated my bios a while ago and when i did i noticed pixels in weird places. I updated from 1.2 i was having problems with crc errors, after that i couldnt run any driver verision on my ati 8500le above 2.5 so i couldnt run 3.0a 3.1. i was just checking if anyone else had these problems when updating to 1.3 on there kt4 ultra. and i flahed twice the first time i thought it was a bad flash or something. i was running 3.0 and downgraded. i am hoping msi will fix this issue but who knows. overclocked or under clocked i still have the problem.
i am running 2.13GHz overclocked from 1.73
kt4ultra
768 ddr400 running at 333MHz
ati 8500le

I've done that, but the problem still exist.
I think it's more like a BIOS problem since there's no problem when I'm runnign 1.1 instead of 1.3

KT4 Ultra: problem config. raid array IDE3

I owe the MSI 6590 KT4 Ultra BSR mainboard and I have difficulties configurring the RAID array in striping mode, on the IDE3 controller.
The manual describes on page 2-18 it's possible to connect up to 2 hard drives, cdrom, 120mb fd and other devices to the IDE3 controller.
Unfortunately only one of my two MAXTOR D740X-6L (6L080J4) 80gig drives is recognized by the array.
One Maxtor hard drive is jumpered as MASTER and the other is set up as SLAVE.
When I hook up the cable to an ordinary IDE port (eg IDE1) the two drives are properly recognized.
Both drives can be formatted using the regular IDE ports, this means without any cluster errors or other errors so the drives are physically OK.
Before I wrote this post I checked the support section again to make sure I am using the latest BIOS which is 1.1. I also downgraded to 1.0, but that didn't solve my problem either.
Since I work in a computer shop now and then I had the opportunity to check two Maxtor Fireball3 30gig drives on a different MS-6590 RAID board (BIOS 1.1.) and exactly the same problem occurs: the 2nd drive won't be recognized in the ARRAY on IDE3.
Please tell me what to do to make the striping option fully work on my two IDENTICAL Maxtor hard drives since MSI support came up with a standard email, which didn't cheer me up at all. Hopefully this time they will investigate this matter since no doubt more people will experience this.

Thanks for the quick response, though it's not satisfactory for me (of course).
Actually before installing the new KT4 Ultra I owed the KT266 Pro RAID motherboard. It's true this board has two controllers for the RAID option. Nevertheless because after reading the manual of this new board I was convinced I could connect two hard drives on the IDE3-channel. This is the reason I decided to go ahead and to upgrade to this new mainboard.
I guess I have to go back to my employer and fall back again to my KT266 (MS6380).

KT4 Ultra - SCSI boot problem

Hi,
I have installed a Tekram DC390U2W LVD SCSI adapter on my KT4 Ultra. My problem is that I cannot select any of the five connected SCSI disks as a boot device in the BIOS (BBS-n), nor can I select 'Legacy SCSI' as a boot device, they simply don't exist as options in the Boot Sequence menu. I've used this card (and were able to boot) without problem using a MSI KT266 motherboard, so I don't think the problem is the SCSI adapter. Any ideas would be appreciated.

I've disabled all motherboard options (Serial ATA Raid/1394/USB 2.0/GBLAN/Audio controllers), remove all PCI cards exept the Tekram card and tried it in all PCI slots without success. Also tried to assign different IRQs to the SCSI card in the BIOS. Tekram support responded that the SCSI card is fully PnP/BBS/PCI 2.1 specification compliant and they're unaware of any KT400 issues. There are issues (and work arounds) with this SCSI card when using it on motherboards with an on-board SCSI controller and older Award BIOS versions, but that's not applicable here.
Anyone out there using this SCSI card and motherboard got this combination to work as intended?

KT4 Ultra-BSR - Drive problems?

Yesterday I purchased a KT4 Ultra-BSR. I am doing a clean install.
I have an Athlon XP200+, 2 x 512MB DDR Ram (PC2100).
On IDE1 I have put 2 x 20GB Western Digital HDs.
On IDE2 I have put a Pioneer DVR-A04 as Master, and a 100GB Western Digital HD as the Slave.
On IDE3 I want a 30GB Western Digital HD as Master, and a 40x Liteon CD-R/W as Slave.
I have installed Windows XP Pro (SP1) from new, and I have installed all of the drivers and utilities from the Drivers CD. My motherboard was shipped with BIOS Version 1.1
When I boot into Windows, I do NOT see the CD-R/W at all.
Also, the only way ro see the HD that's on IDE3 is when it's configured as an array (even though there's only one HD).
I would have preferred to have two HD's on IDE3 but NOT with any form of RAID configuration - is there a way of doing this?
Many thanks

I did it the simple way: Used Fujitsu-Siemens' Plugfree setup instead of the incredibly buggy MSI drivers. Then it worked perfectly with my PocketLoox and Ericsson T39. The hardware is the same. But still the range stinks (max 20 feet on my system), so I bought a full WLan setup instead.
Here's the URL (I belive it says it's only for Fujitsu-Siemens' computers, but that's just standard manufacturer's bull. 8)

You've misunderstood my problem. I have the MSI KT4 Ultra-BSR motherboard which has a bluetooth module which needs to be connected to the motherboard, however, I don't know how to connect it (PHYSICALLY).
Therefore I need someone with the same board to tell me how they did it.

Kt4 ultra problem

hello! i am having a problem with my kt4 ultra.
it originally booted, but once i hit delete to go into setup everything crashed. now when i boot, i get 2 beeps followed by another 8 beeps.
i've done alot of browsing through these forums and other sites, and heres what i find over and over:
10 Short
CMOS register
Check the motherboard and remove all expansion cards and replace one at a time.
i've done this and there is still a problem. am i doing the wrong diagnostics for the 2-8 beep combo?

i cleared cmos by removing battery and via the jumper method. no go.
the cpu/mobo/ram/video/ethernet were in another computer and worked previously. i sold them to my friend and had him buy a new case - i got everything setup the first time, booted, hit del to go into bios to make sure all settings were correct. it crashed and now does the 2-8 combo beep.
previously the mobo was in another case and we used different ram, but i still get the 2-8 beep combo using that same ram.
spec are:
350w ps
kt4 ultra mobo
athlon xp 2200+
geforce 4 ti4600
1 gig ddr 300 ram
30 gig western digital 5400 rpm hd
philips cdrom
netgear ethernet card
+3.3 = 28A
+5 = 35A
+12 = 17A

Serious problems with KT4 Ultra

Hi,
I am having very serious issues with my KT4 Ultra board. Before I go any further here are the specs:
KT4 Ultra w/ AMD Athlon XP 2100+ (not overclocked)
512 MB PC3200 RAM
BIOS V. 1.4
40 Gig HDD ATA 100
ATi Radeon 64 DDR Vivo
PC Alert 4 Temps:
System: 38*C
CPU: 41*C
Apparently everything is within normal specs. However, when I go to play a game like Half-Life my computer often spontaneously reboots itself. I have tried changing/upgrading drivers for almost everything.
Another problem is my onboard sound. It as of late now plays everything in a distorted way. Drivers that I have tried to download for it come up with the message "VIA AC`97 NOT FOUND" Essentially the drivers from VIA dont even think my sound is there (oh but it is.) I had to settle with windows update for this as nothing I can find on this website works. Last but not least, sometimes when I am browsing the web or doing almost nothing, maybe chatting on IM or something, my comp freezes solid. Nothing will work except the reset button. These problems have just lately come about and they are very frustrating. Any reply would be greatly appreciated.

Read my page on lock-ups and reboots as this can be many things.
