KT4 Ultra Overclocking Questions.

I have read the above sticky in regards to this board. MSI (6590) KT 4 Ultra. My questions is this ..I have an AMD Athlon 1800+Xp CPU. In bios for FSb its default is 100...........obviously thats too low because BIOS will under clock the cpu to FSB 100 x whatever the multiplier is. I can set in BIOS as high as 272 mhz and a multiplier of 12.5/13.5 stable for gaming . But how come Wcupid reports the FSB as being 142.34 when its obviously set in BIOS to 272 .........Is that just the CPU FSB multiplier or the actual system FSB ? One would think that if you set the FSB in BIOS to 166 that it should report the FSb as being 166 mhz ........266 in bios should be 266 FSb for system should it not?? .
Anyway the default ghz speed for this CPu is 1.591 GHZ at 266 FSb mhz set in BIOS. But i use the 12.5/13.5/ multiplier which makes it 1730 GHZ CPU speed and reports cpu as XP 2000 + in post info. Now i can go up in increments of 1 in BIOS FSb all the way to 274 ..anything higher is unstable. But i thought this moboard could be overclocked to a 266 mhz FSb . Wcupid shows it as 142.34 right now and the multiplier in BIOS is 12.5/13.5x and the FSB in bios is set to 272 i beleive . Maybe im dumb but can someone explain how this can be.

Sure i do ....If what you say is true ...Because AMi BIOS has a setting for FSB in BIOS which mine is set to 270 MHZ. Im a veteran and i have built CPUs so overclocking is not the issue. The issue is the amount of MHZ i can set in bios that does not equal up to what it should in Wcupid. Please re read my post and you will see what im talking about or go into AMI bIOS ver 1.0 if you are able to and see what im talking about. I can reach 276 in that setting (max with this bios version is 280) but the multiplier has to be dropped to 11.5 to gain stabability. Id rather have a lower 270 setting and higher multiplier just because its stable and is not overheating . I want to know why i cant set that in BIOS to max setting (280) . CPU wont boot if i raise it past 276 at 11.5 multiplying.
With the BIOS setting at 270 and the multiplier at 12.5/13.5 the following info is taken from Wcupid screen
Internal clock 1779 ghz
System BUS 284.68
System clock 142.34 (143)
Multiplier 12.5
Im used to AOPEN jumper setting boards to overclock .

A 350w Powerup powersupply (one that comes with the enermax cs-305 case)
Several Questions:
Processors/memeory
I thinking of changing the processor to an athlon xp. With one should i get? And why is that those processors which have the 333FSB are nearly £90 more expensive??? Does matching the fsb speed to your memeory speed increase peformance too?
Powersupplies
Is my current powersupply sufficient for my setup?
Is this PSW any good_ Q-Tec 550w Dual Fan (that is quite cheap)
And why is this one much more expensive? Enermax 460w
Cooling
using Fuzzy logic 4, the temp displayed is mostly 55-64. Is this too high? And can someone please explian how i find out the full load temps etc.
GFX Cards.
I have the 128MB agp 4x MSI GeForce4 ti4200 card running at 250 core/459 clock usign the MSIO clock tab in desktop properties. Can this safely go any higher?
USB Ports.
On my M/B i can get the top two ports to work fine, but not the bottom two. How come. I have the bracket installed also with the extra 2 usb ports - does this have something to do with it?
Thanks in advance.

1. KT4 Ultra can support upto the fastest XP2700+, you can get it provided you have money... Yes, FSB matching with memory speed the fastest.
2. Enermax has extra features such as fan-control adjust.
3. If it's idle, it's high. to get full load, just run some CPU benchmark and loop it.
4. Your question sounds like "if I buy lottery today will I win?" No comment on the overclockability.
5. Have you enabled ALL USB PORTs in the BIOS?

MSI KT4 ULTRA BSR QUESTIONS

I just bought new stuff for my computer
kt4 Ultra bsr
AOPEN Geforce ti4200 128mb DVI
2200 XP CPU (IN A BOX)
256 ddram 333mhz
so i began rebuilding my computer,
first thing i did was moving the CLEAR CMOS to the right position (by the manual) then it wouldn´t boot, no lights, no fan movement, so i found out later on the internet that it was wrong, so i put the jumper in the other position as shown in the internet.
But when i start up the computer now it only shows
1500 XP 1350 mhz, should be 2200 xp - 1800mhz i think.
but it won´t start with the fsb at 133 mhz. what can i do ????
i have calculated the 5v * 30a + 3.3v * 14 = 196w (dont know what that mean hehe)
i just dont know what´s wrong huff plz anyone help ?

Hi,
unable to run FSB at 133Mhz is either two problem or both:
1. CPU Heatsink did not install properly, thermal grease applied wrongly
2. Power supply does not have enough power
Check both of them.
Your power supply is very weak for today's system. Please consider an upgrade. But don't blindly go for the bigger numbers -- 450W, 550W, survey more to know about the quality of the power supply, especially the +3.3V and +5V rails, which both should supply similar amount of current, ie +3.3V @ 35A, +5V @ 36A for a good 400W. For more insurance, go for the well known brand. But usually they cost more.

Overclocking with MSI KT4 ULTRA

Hi,
I'm currently overclocking my XP 1600+ Palomino to just under an XP 2200+. My Idle temp is 39C and 47C at Load. My CPU is still locked and I'm running at 167FSB x 10.5 = 1758Mhz / 334 Mhz DDR. So far this is the highest stable overclock I am able to get with my current config. I want to get up to atleast a FSB of 180 - 185 to give my GeIL 512MB DDR433 PLATINIUM some sort of challenge, but I can't get the board to post at anything higher than 168FSB. Is it my board topping out or my CPU? What kind of overclocks is everyone else getting with their KT4 ULTRAs? Any help would be greatly appreciated. Thanks )

Hehe so u think all is about MHz!!!????
If u think so go and get some education about overklocking!
I have reached 209FSB!!! Thats overkill!
And im running my system now on the min level x9 Multippel.
And that wil give me a damn strong and powerfull system, I can overklock it to reach the MHz frequence to but i dont right now, i must get a new mobo first, MSI is only !!!
Its up, i wil get a ABIT, or EpOX mobo. then i+ll show u :D
Hmm i have a picture if u want.
But i dont know how to make a link to it, becouse i dont have a webpage now.

KT4-ULTRA questions

Okay I have recently purchased a KT4-ULTRA BSR, i have a 8500le right now thinking of upgrading to either a 9700pro or 9500pro will these cards work? You advertise 8x agp and ddr 400 but i have read nothing but problems running these items? currently i am running pc2700 at 180 fsb no problem! I am just concerned i dont want to spend the money only to have problems!!!! I understand that some of the bugginess is caused by via but are u and via working on fixing the situation?? ?(

Where did you read cache slows system
If you disable the cache it runs slower...Just use the optimized settings from bios and tweak a little bit here and there
You can't really squeeze much performance out unless you overclock some things then it also depends on what you are running under the hood.

Is FSB overclocking above 175 MHz possible with KT4 Ultra?

I would like to squeeze a few extra MHz out of my AMD XP2600+ (without unlocking or other hardmods that cost money if they fail...). I have upped the FSB to 175 successfully, which gives me just above 2200 MHz CPU speed as reported of Motherboard Monitor. But when I go above that, it crashes. Upping the voltage from auto (1.65 on my system) does not seem to help. A guy on an overclocking board suggested that it's because it stops in the AGP/PCI slot since there is no lock of those speeds. Is this possible in any way, or are there any other dirty tricks to use so I can get more speed out of this?
Thanks a lot in advance!

thanks!!!yes, it really seems to be a power source issue...
i am using a powerline 450W power source, and the smart doctor utility form asus reported a reading of red marked warning 3.12 volts intead of 3.3 volts, also i tested the 3.3 rails using a multimeter while the system was on and capture drivers under conflict and it reported a 3.25 voltage.....i opened the power source's box and clean its dust, and so, the problem is not happening anymore!!.anyway smart doctors is reporting a 3.15 voltage instead of 3.3 (not in red or under warning message)and the multimeter is reporting 3.27. but everything is working fine: capture and tv out fetures while using the processor as an athlon 2800+ for the first time since i bought the motherboard........
the 5 volts line is reported by the multimeter with 4.95 volts after and before the problem was happening, same with smart doctor.
the hardware i used was:
-two MSI kt4 ultra boards
-kt4A
-an intel motherboard which i don't remember its brand, using dimm pc 133 memory(using anoter power supply)
-asus v8460 for all boards
-same ddr memory for all msi motherboards
since the voltage is still not 3.3 volts reported, even if the entire video card is working fine, and i only cleaned the box, and didn't change anything to its structure, maybe the problem could happen again, i guess i should buy another power source then.
i am very thankful
Andres.
PD: i see that a lot of people is having this kind of problem through the forum and maybe its due to this voltage stuff too....maybe it'd be a good idea if a sticky thread is posted repoting this stuff i believe. (if it hasn't yet of course)

KT4 Ultra Question

ok well this might be stupid of me to ask..but to me there are no stupid questions.
What is the best way to set up my hard drive and cd rom....can i use ATA 1 master and 1 slave..or do i need to use the ide 1 and ide 2 or how does it work...im just wondering if it would be better for me or should i leave things the way they are....i know this board has 1 ata slot and the harddrive supports ata..so i was just curious.
Specs.
MSI KT4 Ultra SR BIOS V1.3
Athlon XP 1700+ ThouroughBred @1.7ghz 140x12.5=1755Mhz
512 MB DDR PC2100 266Mhz

SoundBlaster Live Gamer 5.1 pci sound card
Maxtor 20Gb HD DiamondMax Plus D740X
Antec SL400 400watt PSU

you don't say what kind of cd-rom you have but anyways...
Set each up as a master on their own channel. If you set them up on the same channel, the channel will only run as fast as the slowest device, thus making your hard drive run slower.

Can't overclock my 2400XP on KT4 Ultra

Hi All,
I am trying to overclock my new config
2400XP running @133 fsb
MSI KT4 Ultra BSR
256mb DDR 2700
Volcano 9 HSF
Windows XP Professional
I've installed the board and only amended the fsb in the bios from 100 to 133 to set at 2ghz. If I use the Fuzzy logic to up the speed, it gets to about 135on the fsb and just reboots XP. I have tried amending bios settings such as :
1. fsb 135 on bios only, no change to voltage or multipler
2. fsb 166, clock multipler 13.5
In every case, this just results in locking the board down X( and having to do a bios jumper reset to recover........what am I doing wrong?
Thanks for any help on this. Everyone keeps saying that this chip is easily overclockable, but I can't get it to work.
Nigel

Basically, I suggest you set all voltages and multipliers at default >set FSB to 166 (1/5 divider kicks in at 152), and you should be off and running - always watching temps! That's what I did with my new (older model) KT3 Ultra as soon as I installed it. (EDIT: I also had RAM set at SPD/Normal/1t disabled.)
Enermax 350 could be enough depending on what gear you have.
If you're new to overclocking, I'd stop at 166 FSB, and review this o/c guide (you can damage your system going off half-cocked). Page down slightly to Beginner's Guides:

Good luck to all. )

KT4 Ultra CPU Upgrade Question

I am trying to upgrade my CPU from a 2100 XP to a 2800 XP on my KT4 Ultra and am running into trouble. I was under the impression that all I had to do was turn up the FSB frequency in CMOS and everything would be OK howerver this doesn't appear to be the case. Currently the FSB Freq. is set to 100 and I can get it above 104 or the system will not POST. Has anyone out there put a 2800 with the latest BIOS in a KT4? What setting need to be changed and what values should be used in CMOS??
Help please!!!!

set to 166

MSI KT4 Ultra! A little question.

Hello. )
I'm very interested, in the new MSI KT4 Ultra, but i've a doubt:
The pure version of the KT4 Ultra, has a fan on the chipset?
How many IDE channels come with this pure version?
Thank you, and sorry about my poor english. :D

You can modify de FSB in the bios, but there is a jumper that provides these 3 options, 100mhz, 133mhz and 166mhz. 100mhz for the duron cpu's, 133mhz for the Athlon xp Palomino and Tbred, and 166mhz for the athlon xp Barton ( not 100% confirmed).

JIUHB TBred 1700+ and KT4 Ultra

Hi,
this is my first time being in this forum )
I have a question about overclocking my new TBred 1700+ (JIUHB stepping) CPU on my KT4 Ultra board.
After i have installed the CPU on my board i changed the FSB to 166 MHz - no problem the FSB is running with 166 MHz :P . Then i want to change the multiplier from 11 (default) to 12.5 -> nothing happens - the multiplier is still 11 ?( When i set the multiplier to 10 also nothing happens - the multiplier is still 11. The cpu itself should not be the problem (the CPU should be unlocked by default) because i have bought two of them and the other CPU runs on an KT3 Ultra 2 board with FSB 166 and with a multiplier 12.5. Can anyone help me or tell me what the problem could be.
System configuration :
KT4 Ultra (Bios 1.30)
2x256 MByte RAM PC-333 (CL2,5 - Infineon)
Leadtek A280 TD - 64 MByte
80 GByte HD - Barracuda V
Juergen

additional info :
in another thread ("Is my Athlon XP 2400+ Tbred B Unlocked? Please help!") i found the information that with the KT4 Ultra board the only way to unlock the cpu is the wiring trick.
@jkesa - is this what is to do when the L1 bridges are cut ?(
@maesus - is there any hope that this overclocking feature is maybe implemented in the forthcoming 1.4 bios to avoid such kind of modification like the wiring trick (other mainboards are able to do that) ?(

Help... KT4 Ultra

Hi,
I Have the KT4 ultra + AMD XP 2400+ (FSB 266)
My questions :
1) Why I can't change the CPU cpu multiplier from "AUTO" to manual "15X".
If I change anything but "AUTO" the system hangs.. Is it normal?
2) I wold like to understand how to overclock an unlocked XP2400+(133x15) to (12x166) if the multiplier desn't work...
Thanks..

To answer your questions
1) Why I can't change the CPU cpu multiplier from "AUTO" to manual "15X".
If I change anything but "AUTO" the system hangs.. Is it normal?
Yes, it is normal because your CPU is locked and you can't change the multiplier without doing some bridge unlocking.
2) I wold like to understand how to overclock an unlocked XP2400+(133x15) to (12x166) if the multiplier desn't work...
If it does not work, then it's possible that your cpu is not unlocked properly. TBred's are not unlocked the same way as Palomino chips (XP 2000+ and lower speeds).

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 temp XP cooler and performance

hola, please intruct me
ive just build my kt4 ultra with an atlhon XP 2,2
and my temps are cpu 58 C when midle loaded and system temp 52 C, i dont know i its normal, im using the cooler that comes with the cpu
my question is that temp normal?
when i use the XP cooler of pc alert, the performance of the sistem change? how much?
thank you
excuse my english

The system temp sensor may be between the first PCI slot and AGP slot, or somewhere near there if not mistaken. If you use a hot graphics card, that part will get hot too. Even it it's not, bad air flow around that area will accumulate heat too. Try with your casing fully opened and compare. If the temp dropped, then it's OK. If not, then you might have an issue.
Again, as long as it's stable, any temperature is OK.

KT4 Ultra: conflict w/ expansion cards

This is my first post, so please be gentle. I recently built new PC for photo editing and want to keep this old KT4 Ultra computer for general usage right beside. Both are running Windows XP Home SP3.
My KT4 computer had HDD crash and after replacement and fresh istallation of XP I initially had following expansion cards inside:
USB Expansion card (w/ 4 USB ports) on Slot 2 (INT B#)
Realtek RTL8139 Family PCI Fast Ethernet NIC on Slot 3 (INT D#)
Terratec EWX 24/96 Sound Card on Slot 6 (INT C#)
Everything was OK until I wanted a LAN connection for sharing of files (mostly) and Internet (via cable modem) between these two. Instead of a broadband wired router I opted for a Gigabit Ethernet card installing it on slot 5 (INT B#).
USB Expansion card (w/ 4 USB ports) on Slot 2 (INT B#)
Realtek RTL8139 Family PCI Fast Ethernet NIC on Slot 3 (INT D#)
D-Link DGE-528T Gigabit Ethernet Adapter on Slot 5 (INT B#)
Terratec EWX 24/96 Sound Card on Slot 6 (INT C#)
Somehow didn't want to have it on slot 1, so close to video card. Unfortunately after this the sound card was dropped by the system, a yellow question mark in Device Manager.
Further I failed to instal my Bluetooth Dongle which I earlier had used succesfully for communication to my mobile phone. Now my Broadcom USB Bluetooth Device is put under Unknown in Device Manager.
I did experience problems with the sound card several years ago in this very same PC. That time I knew little about system and BIOS setting and had to use another PC for audio purposes (digitalizing of tapes and vinyl).
As reference I used the PCI Interrup Request Routing table, found on page 2-32 in KT4's manual. Funny thing is that Sandra XI tells now that my two Ethernet cards having both INT pin A# while by their slots they should be B# and D#. I don't have true understanding what this means though. In BIOS the PNP/PCI Configurations has all slot IRQs on Auto.
Is this conflict easily cured by re-positioning card(s) on other slot(s) or addressing IRQ settings manually, and if so how and in which order? Or should I remove all the cards and install them in certain order...?
I'm quite exhausted as I had some component issues with my new PC and now this KT4 once again rejects my sound card. Maybe I'm better off by installing it on my new PC, but then this failure with Bluetooth dongle, (which I put on the USB port of KT4, not on the USB exp. card.) Oh my, why can't sound card and ethernet card live together!?!
I would appreciate your help very highly.

Hope you get things like you want them!
Eh, made this in 2003, but I'm not sure if it isn't more confusing than anything else:
"The use and sharing of IRQs aren't mentioned in my MSI manual, (due to the APIC function I think), so I had to go to some ASUS manuals. As standards are standards, I believe things can't be to different. If someone has any addings or suggestions please come forward, so I can adjust the table.
*Please note that this is generally speaking and mainly for ASUS boards a few years old!
**Please note that you should not have any sharing with the IDE controller or similar!
***Please note that it is a good thing to have expansion PCI sound cards in slot 3!
****Please note that surprisingly enough it looks like PCI slot 2 would be free for any device, but AGP cards get hot and bigger so it is not a great idea.
IRQ sharing table
PCI 1 shares with PCI slot 5
2 shares with AGP and PCI slot 6, or sometimes with onboard IDE
3 shares not, or sometimes with onboard audio/modem
4 shares with onboard LAN
5 shares PCI slot 1
6 shares with AGP and PCI slot 5
AGP slot shares with PCI slots 5 and 6
USB 1 shares with USB 2, 3 and USB 2.0
2 shares with USB 1, 3 and USB 2.0
3 shares with USB 1, 2 and USB 2.0
USB 2.0 shares with USB 1, 2, and 3
Onboard audio/modemshares not, or sometimes with slot 3
Onboard LAN shares with PCI slot 4
Onboard IDE shares not, or sometimes with PCI slot 2 "
Normally it is best to let Windows or whatever OS you run do the job. Setting IRQ:s yourself is a (too) big assignment.
